Estimating the total cost of producing 100 bars tools using the left-rectangle approximation with five rectangles, we conclude that the total cost is approximately $
The total cost of producing 100 bar stools using the left-rectangle approximation with five rectangles is approximately $200.
The marginal cost function for producing the x-th item of a certain brand of bar stool is given by MC(x) = 20 - 0.5x, where 0 ≤ x ≤ 100. To estimate the total cost of producing 100 bar stools using the left-rectangle approximation with five rectangles, we first need to calculate the width of each rectangle.
The width of each rectangle is (100 - 0) / 5 = 20.
Now, we will evaluate the marginal cost function at the left endpoints of each rectangle:
MC(0) = 20 - 0.5(0) = 20
MC(20) = 20 - 0.5(20) = 10
MC(40) = 20 - 0.5(40) = 0
MC(60) = 20 - 0.5(60) = -10
MC(80) = 20 - 0.5(80) = -20
Next, multiply each value by the width (20) and sum the results to approximate the variable cost:
Variable cost ≈ 20(20) + 10(20) + 0(20) + (-10)(20) + (-20)(20) = 400 + 200 - 200 - 400 = 0
Finally, add the fixed cost of $200 to the variable cost:
Total cost ≈ $200 + $0 = $200
So, the total cost of producing 100 bar stools using the left-rectangle approximation with five rectangles is approximately $200.

Service fee for the over the counter deposit of R700: R10.50
Service fee for the ATM withdrawal of R500: R11.50
To determine the service fee that Tilly will incur for the given transactions,
Over the Counter Deposit of R700:
Tilly is depositing R700, the fee will be:
Fee = R3.50 + (R1.00 per R100) x (R700 / R100)
= R3.50 + R7.00
= R10.50
Therefore, the service fee for the over the counter deposit of R700 is R10.50.
ATM Withdrawal of R500:
The fee for an ATM withdrawal at own bank is calculated as R6.50 + R1.00 per R100.
Since Tilly is withdrawing R500, the fee will be:
Fee = R6.50 + (R1.00 per R100) x (R500 / R100)

Determine the distance between the points (−3, −6) and (5, 0).
The distance between the points (-3, -6) and (5, 0) is 10 units.
What is the Pythagorean theorem?Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.
To determine the distance between two points in a coordinate plane, you can use the distance formula, which is derived from the Pythagorean theorem.
The distance formula for two points (x₁, y₁) and (x₂, y₂) in a coordinate plane is:
Distance = √{(x₂ - x₁)² + (y₂ - y₁)²}
Given the two points (-3, -6) and (5, 0), we can plug in the values into the distance formula as follows:
x₁ = -3, y₁ = -6 (coordinates of the first point)
x₂ = 5, y₂ = 0 (coordinates of the second point)
Distance = √{(x₂ - x₁)² + (y₂ - y₁)²}
= √{(8)² + (6)²}
= √{(64) + (36)
= √100
= 10
Hence, the distance between the points (-3, -6) and (5, 0) is 10 units.

Vanessa's team played 8 games of basketball. During those 8 games her team's score was: 68, 76, 63, 58, 64, 75, 78 and 78.
What is the mean absolute deviation?
Please help!! Please answer it correctly too!!!! Whoever gets it correct gets brainliest!! and then I will give them 154 points!!!! please!!
The mean absolute deviation is 6.25.
To find the mean absolute deviation (MAD), we first need to find the mean of the scores:
Mean = (68 + 76 + 63 + 58 + 64 + 75 + 78 + 78) / 8 = 69.5
Next, we need to find the absolute deviation of each score from the mean. The absolute deviation is the absolute value of the difference between the score and the mean.
For example, the absolute deviation of the first score (68) is:
|68 - 69.5| = 1.5
We can calculate the absolute deviation for each score:
|68 - 69.5| = 1.5
|76 - 69.5| = 6.5
|63 - 69.5| = 6.5
|58 - 69.5| = 11.5
|64 - 69.5| = 5.5
|75 - 69.5| = 5.5
|78 - 69.5| = 8.5
|78 - 69.5| = 8.5
To find the MAD, we take the average of the absolute deviations:
MAD = (1.5 + 6.5 + 6.5 + 11.5 + 5.5 + 5.5 + 8.5 + 8.5) / 8 = 6.25
Therefore, the mean absolute deviation is 6.25.

24. Anna, Berta, Charlie, David and Elisa baked biscuits at the weekend. Anna baked 24, Berta
25, Charlie 26, David 27 and Elisa 28 biscuits. By the end of the weekend one of the children had
twice as many, one 3 times, one 4 times, one 5 times and one 6 times as many biscuits as on
Saturday. Who baked the most biscuits on Saturday?
(A) Anna (8) Berta (C) Charlie (D) David (E) Elisa
At the end of the weekend, Elisa had the most biscuits (168). So, the answer is (E) Elisa baked the most biscuits on Saturday.
To determine who baked the most biscuits on Saturday, we need to calculate how many biscuits each child had at the end of the weekend.
Anna had 24 biscuits, Berta had 25, Charlie had 26, David had 27, and Elisa had 28.
Let's start with the child who had twice as many biscuits as on Saturday. We can divide their total number of biscuits by 2 to get the number they had on Saturday.
If we try this calculation for each child, we find that only Elisa's total number of biscuits (28) is evenly divisible by 2. Therefore, Elisa must be the child who had twice as many biscuits as on Saturday, meaning she had 14 biscuits on Saturday.
We can use a similar process to determine how many biscuits each child had on Saturday:
- The child who had three times as many biscuits as on Saturday must have had a total of 42 biscuits, which means they had 14 biscuits on Saturday.
- The child who had four times as many biscuits as on Saturday must have had a total of 56 biscuits, which means they had 14 biscuits on Saturday.
- The child who had five times as many biscuits as on Saturday must have had a total of 70 biscuits, which means they had 14 biscuits on Saturday.
- The child who had six times as many biscuits as on Saturday must have had a total of 84 biscuits, which means they had 14 biscuits on Saturday.
Now we can add up the number of biscuits each child had on Saturday:
- Anna had 24 biscuits.
- Berta had 25 biscuits.
- Charlie had 26 biscuits.
- David had 27 biscuits.
- Elisa had 14 biscuits.
Therefore, David baked the most biscuits on Saturday with 27.
To determine who baked the most biscuits on Saturday, we need to consider the information given about the multiplication factors (twice, 3 times, 4 times, 5 times, and 6 times) and the initial number of biscuits baked by each child.
1. Anna baked 24 biscuits.
2. Berta baked 25 biscuits.
3. Charlie baked 26 biscuits.
4. David baked 27 biscuits.
5. Elisa baked 28 biscuits.
Now, let's apply the multiplication factors and see which child had the most biscuits at the end of the weekend:
1. Anna: 24 x 2 = 48
2. Berta: 25 x 3 = 75
3. Charlie: 26 x 4 = 104
4. David: 27 x 5 = 135
5. Elisa: 28 x 6 = 168
At the end of the weekend, Elisa had the most biscuits (168). So, the answer is (E) Elisa baked the most biscuits on Saturday.

The perimeter of the rectangle below is 16 cm. What is the value of k? 5 cm kcm Not to scale
Answer:
3 cm.
Step-by-step explanation:
Let's use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.In this case, we have:P = 16 cm (given)
l = k cm (given)
w = 5 cm (given)Substituting these values into the formula, we get:
16 cm = 2(k cm) + 2(5 cm)
Simplifying, we get:
16 cm = 2k cm + 10 cm
Subtracting 10 cm from both sides, we get:6 cm = 2k cm
Dividing both sides by 2, we get:
3 cm = k
Therefore, the value of k is 3 cm.

i) The angle XYZ in which XY= 8.3 cm, YZ= 11.9 cm is constructed.
ii) M the midpoint of XZ where XYZ= 60 is constructed.
iii) The measure of YM is 6.3 cm
Firstly, you are asked to construct an angle XYZ where XY= 8.3 cm and YZ= 11.9 cm. To construct an angle, we need to follow a few steps.
Draw a line segment XY of length 8.3 cm.
At point Y, draw a ray YZ extending in the direction of Z.
Using a compass, draw an arc of radius 11.9 cm from point Y, intersecting the ray YZ at point Z.
The angle XYZ is the angle formed by the line segments XY and YZ.
Now, you need to construct the midpoint M of XZ. The midpoint of a line segment is the point that divides it into two equal parts. To construct the midpoint, we follow these steps:
Draw a line segment XZ joining points X and Z.
Using a compass, draw an arc of radius greater than half of XZ from point X.
Using the same radius, draw another arc from point Z intersecting the first arc at point P.
Draw a line through points X and P, and another line through points Z and P. These two lines will intersect at the midpoint M of line segment XZ.
Finally, you are asked to measure angle YM. To measure an angle, we use a protractor.

Answer:
it should be 1/10 if that helps you
Answer:
0.01 does not have the same value as the others.
Step-by-step explanation:
10/100, 10%, and 1/10 is all the same. 0.01 is NOT the same because it is equal to 1/100, or 1% while the others were all equal to 10%. To figure this out, you must multiply 0.01 by 100 (or move the decimal point one space to the right two times) and we will get 1. This means that 0.01 is 1% which is also equal to 1/100, therefore it does not obtain the same value as the others.

Answer: So, according to this prediction, a book with 19 chapters would have approximately 950 pages. However, keep in mind that this is just a prediction based on the trend line, and there may be some variability in the actual number of pages for a book with 19 chapters.
Step-by-step explanation:
Unfortunately, I cannot see the scatter plot you are referring to. However, I can explain how to use a trend line to predict the number of pages in a book with 19 chapters.
A trend line is a line that represents the general direction or tendency of the data in a scatter plot. To use a trend line to predict the number of pages in a book with 19 chapters, you would first need to determine the equation of the trend line.
This equation usually takes the form y = mx + b, where y is the dependent variable (in this case, the total number of pages), x is the independent variable (in this case, the number of chapters), m is the slope of the line, and b is the y-intercept (the value of y when x is 0).
Once you have the equation of the trend line, you can plug in the value x = 19 and solve for y to get the predicted number of pages in a book with 19 chapters.
For example, if the equation of the trend line is y = 50x + 200, then the predicted number of pages for a book with 19 chapters would be:
y = 50(19) + 200
y = 950
So, according to this prediction, a book with 19 chapters would have approximately 950 pages. However, keep in mind that this is just a prediction based on the trend line, and there may be some variability in the actual number of pages for a book with 19 chapters.

coordinates of P = (2,-8) = (x3,y3)
and distance between point M and P is half of the distance between FG
To find :- first coordinate of point M
solution :- let the coordinate of M be (x4,y4)
as we know that distance between of the opposite point of parallel line segments are equal
so, second coordinate of M = -8
now by distance formula
FG = √(x2-x1)² + (y2-y1²)
= √[2-(-4)]² + [-2-(-2)]²
= √(2+4)² + (2-2)²
= √(6)² + (0)²
=√36
F G = 6
so, distance between point M and P = 1/2 × F G
= 1/2 × 6
= 3units
again, by distance formula
MP = √(x3-x⁴)² + (y3-y4)²
3 = √(2-x⁴)² + [-8-(-8)]²
squaring on both side
(3)² = (√(2-x⁴)² + [-8-(-8)]²)²
9 = (2-x⁴)² + [-8-(-8)]²
9 = (2-x⁴)²+(0)²
9 = (2-x⁴)²
√9 = 2-x⁴
3 = 2-x⁴
x⁴ = 2-3
x⁴ = -1
Hence the first coordinate of M is -1

A machine has an initial cost of $40,000 and operating costs of $3500 each year. Its salvage value decreases by $4,000 each year. The machine is now 4 years old.
Assuming an effective annual interest rate of 12%, what is the cost of owning and operating the machine for one more year.
The cost of owning and operating the machine for one more year is approximately $11,160.71.
To calculate the cost of owning and operating the machine for one more year, we need to consider both the operating costs and the decrease in salvage value.
The operating costs for one more year will be $3,500.
To calculate the decrease in salvage value, we need to know the salvage value of the machine after 4 years of use. If the salvage value decreased by $4,000 each year, then after 4 years the salvage value will have decreased by $16,000. Therefore, the salvage value of the machine after 4 years is:
Salvage value after 4 years = Initial salvage value - Total decrease in salvage value
Salvage value after 4 years = $40,000 - $16,000
Salvage value after 4 years = $24,000
To calculate the cost of owning and operating the machine for one more year, we need to consider the difference between the salvage value at the end of the additional year and the salvage value after 4 years. Assuming a straight-line depreciation model, the salvage value of the machine after one more year will be:
Salvage value after one more year = Salvage value after 4 years - (4 x $4,000)
Salvage value after one more year = $24,000 - $16,000
Salvage value after one more year = $8,000
To calculate the cost of owning and operating the machine for one more year, we need to calculate the present value of the difference between the salvage values, plus the operating costs for one more year. Assuming an effective annual interest rate of 12%, the present value can be calculated using the formula:
PV = FV / (1 + r[tex])^n[/tex]
where PV is the present value, FV is the future value, r is the effective annual interest rate, and n is the number of years.
The future value of the salvage value difference plus the operating costs for one more year is:
FV = Salvage value after one more year - Salvage value after 4 years + Operating costs for one more year
FV = $8,000 - $24,000 + $3,500
FV = -$12,500
(Note that the negative value indicates a cost.)
Plugging in the values, we get:
PV = -$12,500 / (1 + 0.12[tex])^1[/tex]
PV = -$11,160.71
Therefore, the cost of owning and operating the machine for one more year is approximately $11,160.71.

The number of solutions that are there for the pair of equations for lines Q and S is zero solution (no solution) because the lines are parallel with no point of intersection.
What is no solution?In Mathematics and Geometry, no solution is sometimes referred to as zero solution, and an equation is said to have no solution when the left hand side and right hand side of the equation are not the same or equal.
This ultimately implies that, a system of equations would have no solution when the line representing each of the equations are parallel lines and have the same slope i.e both sides of the equal sign are the same and the variables cancel out.

When are the lower and upper quartiles calculated by finding the average of two values
The lower and upper quartiles are calculated by finding the average of two values when there is an even number of data points in the dataset. Specifically, the lower quartile (Q1) is the average of the middle two values when the dataset is sorted in ascending order, and the upper quartile (Q3) is the average of the middle two values when the dataset is sorted in descending order.
When are the lower and upper quartiles calculated by finding the average of two values The lower and upper quartiles are values that divide a dataset into four equal parts. The lower quartile (Q1) marks the point below which the lowest 25% of the data falls, and the upper quartile (Q3) marks the point below which the highest 25% of the data falls. When there is an odd number of data points in the dataset, Q1 and Q3 are the median of the lower half and upper half of the dataset, respectively. However, when there is an even number of data points, there is no exact middle value, so the lower and upper quartiles are calculated by averaging the two values that fall in the middle. This ensures that Q1 and Q3 still divide the dataset into four equal parts.

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes in the context of a problem/experiment.
The dice has eight sides, hence the theoretical probability of rolling a six is given as follows:
1/8 = 0.125 = 12.5%.
The experimental probabilities are obtained considering the trials, hence:
100 trials: 20/100 = 0.2 = 20%.400 trials: 44/400 = 0.11 = 11%.The more trials, the closer the experimental probability should be to the theoretical probability.

By using Pythagoras' theorem, triangle 3 and 4 is a right triangle, and others are not.
What is the triangle?
A triangle is a three-sided polygon with three vertices. The angle produced within the triangle is 180 degrees.
What is right-angled triangle?
A right-angled triangle is one with one of its interior angles equal to 90 degrees, or any angle is a right angle.
According to the given information:
The Pythagorean theorem states that " In a right-angled triangle, the square of the hypotenuse is equal to the sum of squares of the other two sides"
Let's check fig (3)
[tex]15^{2} =12^{2} +9^{2}[/tex]
225 = 144 + 81
225 = 225
both sides are equal, Therefore it is a right-angled triangle.
Let's check fig (4)
[tex]48.5^{2}=39^{2}+32.5^{2}[/tex]
2352.25 = 1521 + 1056.25
2352.25 ≠ 2577.25
Both sides are not equal, Therefore it is not a right-angled triangle.
Let's check fig (5)
[tex]11^{2}=9^{2}+\sqrt{115} ^{2}[/tex]
121 = 81 + 115
121 ≠ 196
Both sides are not equal, Therefore it is not a right-angled triangle.
Let's check fig (6)
[tex]16^{2} = 10^{2} + (2\sqrt{39}) ^{2}[/tex]
256 = 100 + 156
256 = 256
both sides are equal, Therefore it is a right-angled triangle.
Hence figure 3 and 6 is right angle triangle, others are not.

All juniors and seniors at a high school were surveyed about whether they had ever had a summer job. This graph shows the data from the survey. PART A Based on the graph, what is the total number of students who were surveyed?
The total number of students who were surveyed is 575
The graph likely displays a horizontal axis and a vertical axis.
In this graph, the horizontal axis may indicate two categories, such as "juniors" and "seniors," and the vertical axis shows the number of students in each category who responded "yes," "no," or "not sure."
To find the total number of students surveyed, we need to look for the bar that represents the entire group of juniors and seniors. Typically, this bar will be labeled as "total," "all," or something similar. Once we locate this bar, we can add up the number of students represented by the bar. The value will be displayed on the vertical axis, and it should correspond to the sum of the bars for juniors and seniors separately.
