A data set is normally distributed with a mean of 27 and a standard deviation of 3.5. About what percent of the data is greater than 34?
Answer:
Approximately 2.5% of the data is greater than 34.
Step-by-step explanation:
To solve this problem, we need to use the empirical rule (also known as the 68-95-99.7 rule) for a normal distribution. This rule states that about 68% of values lie within 1 standard deviation of the mean, about 95% of the values lie within 2 standard deviations of the mean, and about 99.7% of the values lie within 3 standard deviations of the mean.
The mean of the dataset is 27, and the standard deviation is 3.5.
34 is exactly 2 standard deviations away from the mean (since 27 + 2*3.5 = 34). According to the empirical rule, about 95% of the data falls within this range. This means that about 5% of the data is outside of this range.
Since the normal distribution is symmetrical, the data outside of 2 standard deviations is equally split between values that are too large and too small. Hence, about half of this 5%, or 2.5%, is greater than 34.
Therefore, approximately 2.5% of the data is greater than 34.

A gazebo in the shape of a regular hexagon (six sides) has side length s and apothem a. If the cost per square unit of flooring is c, express the total cost T of the floor algebraically.
The total cost T of the floor algebraically is T = c x (3√3/2) x s²
We have,
To express the total cost T of the floor of the hexagonal gazebo algebraically, we need to consider the area of the hexagonal floor and the cost per square unit of flooring.
The area of a regular hexagon can be calculated using the formula:
Area = (3√3/2) x s²
Where s is the side length of the hexagon.
To find the total cost, we multiply the area by the cost per square unit of flooring (c):
T = c x Area
Substituting the area formula into the equation:
T = c x (3√3/2) x s²
Now, we have expressed the total cost T algebraically in terms of the side length s and the cost per square unit of flooring c.
Thus,
The total cost T of the floor algebraically is T = c x (3√3/2) x s²

Find the perimeter of the figure. All angles in the figure are right angles.
A. 82 cm
B. 59 cm
C. 77 cm
D. 356.25 cm
Answer:
A. 82 cm
Step-by-step explanation:
You want the perimeter of the L-shaped figure that is 12.5 cm high and 28.5 cm wide.
Side lengthsThe top two horizontal line segments have the same total length as the bottom horizontal line segment. We don't need to figure what the missing length is, because we only need their total for the perimeter.
The right side two vertical line segments have the same total length as the left vertical line segment. As with the horizontal segments, we don't need to figure out the missing length, because we only need their total for the perimeter.
PerimeterThe perimeter is the sum of horizontal line segments plus the sum of vertical line segments:
2(28.5 cm) + 2(12.5 cm) = 57 cm + 25 cm = 82 cm
The perimeter of the figure is 82 cm.

1) Graph the parametric path using Slope-Direction diagram.
The curve is x = t^2,y = (t - 1)(t^2 - 4), for t, in [-3,3]
2) Find the length of the pay over the given interval.
(2cost - cost2t, 2sint - sin2t), 0 ≤ t ≤ π/2
Please give step-by-step.
To graph the parametric path x = t^2, y = (t - 1)(t^2 - 4) on a Slope-Direction diagram, we need to plot points by evaluating the expressions for different values of t within the given interval [-3, 3].
First, let's calculate the coordinates for several values of t:
For [tex]t = -3: x = 9, y = 0[/tex]
For[tex]t = -2: x = 4, y = 6[/tex]
For [tex]t = -1: x = 1, y = 0[/tex]
For [tex]t = 0: x = 0, y = -4[/tex]
For[tex]t = 1: x = 1, y = 0[/tex]
For[tex]t = 2: x = 4, y = 6[/tex]
For [tex]t = 3: x = 9, y = 0[/tex]
Plotting these points on the Slope-Direction diagram, we can observe the shape of the curve. The path starts at (9, 0), moves downward to (4, 6), reaches the lowest point at (0, -4), and then goes back up to (4, 6) and (9, 0).
To find the length of the curve given by (2cost - cost2t, 2sint - sin2t) over the interval 0 ≤ t ≤ π/2, we can use the arc length formula:
L = ∫√(dx/dt)² + (dy/dt)² dt
First, calculate the derivatives of x and y with respect to t:
dx/dt = -2cost - 2costsin2t
dy/dt = 2cost - 2sintcos2t
Next, square and add these derivatives:
(dx/dt)² + (dy/dt)² = 4cost² + 4costsin2t + 4cost² + 4sint²cos²2t
Simplify the expression:
(dx/dt)² + (dy/dt)² = 8cost² + 4costsin2t + 4sint²cos²2t
Now, integrate the square root of this expression over the given interval 0 ≤ t ≤ π/2 to find the length of the curve:
L = ∫√(8cost² + 4costsin2t + 4sint²cos²2t) dt, from 0 to π/2
Evaluating this integral will provide the final answer for the length of the curve.

One of your customers is delinquent on his accounts payable balance. You’ve mutually agreed to a repayment schedule of $570 per month. You will charge .97 percent per month interest on the overdue balance. If the current balance is $14,790, how long will it take for the account to be paid off?
Note: Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.
Answer:
To calculate the time it will take to pay off the account, we can use the formula for the future value of an annuity:
PV = PMT * ((1 - (1 + r)^(-n)) / r)
Where:
PV = Present value (current balance)
PMT = Payment amount per period
r = Interest rate per period
n = Number of periods
In this case:
PV = $14,790
PMT = $570
r = 0.0097 (0.97% expressed as a decimal)
n = ?
Plugging in the values, we can solve for n:
14,790 = 570 * ((1 - (1 + 0.0097)^(-n)) / 0.0097)
Let's solve this equation to find the value of n:
((1 + 0.0097)^(-n)) = 1 - (14,790 * 0.0097) / 570
((1 + 0.0097)^(-n)) = 0.9742105
Taking the logarithm of both sides:
-n * log(1.0097) = log(0.9742105)
n = log(0.9742105) / log(1.0097)
Using a calculator, we find that n is approximately 28.56.
Therefore, it will take approximately 28.56 months (or 28 months and 17 days) to pay off the account.
Step-by-step explanation:
A man undertakes to pay off a debt of Rs. 622500 by monthly installments, he pays Rs. 10000 in the first month and continually increases the installments in every subsequent month by Rs. 100. In what time will the debt be cleared up?
The debt will be cleared in approximately 158 months.
In how many months will the debt be cleared?The monthly installment starts at Rs. 10,000 and increases by Rs. 100 each month. We can set up an arithmetic progression to represent the installment amounts:
10,000, 10,100, 10,200, ...
The nth term of this arithmetic progression can be calculated using the formula:
an = a1 + (n-1)d
where:
an = nth term of the sequence
a1 = first term of the sequence
d = common difference between the terms
In this case, a1 = 10,000 and d = 100.
Now we need to find the value of n such that the sum of the first n terms of the sequence exceeds or equals Rs. 622,500.
The sum of the first n terms of an arithmetic sequence can be calculated using the formula:
Sn = (n/2)(2a1 + (n-1)d)
We need to solve the equation:
Sn >= 622,500
Substituting the values, we have:
(n/2)(2*10,000 + (n-1)*100) >= 622,500
Simplifying the equation, we can solve for n:
n^2 + 199n - 614000 = 0
Using the quadratic formula, we find that:
n ≈ 157.37 or n ≈ -356.37
Since we cannot have a negative number of months, we take n ≈ 157.37. Therefore, it will take approximately 158 months (rounded up) to clear the debt.
Hence, the debt will be cleared in approximately 158 months.

if the AREA of a rectangular garden is x^2-36 and the length is x^2-2x-24, find an expression to represent the width of the garden.
To find an expression representing the width of the rectangular garden, we need to use the given information about the area and length of the garden.
The formula for the area of a rectangle is:
Area = Length × Width
We are given that the area of the garden is x^2 - 36, and the length is x^2 - 2x - 24.
Let's substitute these values into the formula:
x^2 - 36 = (x^2 - 2x - 24) × Width
To isolate the width, we divide both sides of the equation by (x^2 - 2x - 24):
Width = (x^2 - 36) / (x^2 - 2x - 24)
Therefore, an expression representing the width of the garden is:
Width = (x^2 - 36) / (x^2 - 2x - 24)

Step-by-step explanation:
Let's start by finding the total cost of the sodas. We know that there were 5 sodas and each cost $0.75, so the total cost of the sodas is:
5 * $0.75 = $3.75
Next, we need to subtract the cost of the sodas from the total cost before tax to find the cost of the pizzas:
$33.70 - $3.75 = $29.95
Finally, we can divide the cost of the pizzas by the number of pizzas to find the cost of each pizza:
$29.95 ÷ 5 = $5.99
Therefore, the cost of each pizza pie was $5.99. Answer choice B is correct.

The zero 3 gives us the factor (x - 3).
The zero -i gives us the factor (x + i) since complex zeros always come in conjugate pairs.
The zero 9+i gives us the factor (x - (9+i)).
Now, we can multiply these factors together to obtain the polynomial:
f(x) = (x - 3)(x + i)(x - (9+i))
Next, we simplify the expression:
f(x) = (x - 3)(x + i)(x - 9 - i)
Expanding the product, we have:
f(x) = (x^2 + xi - 3x - 3i)(x - 9 - i)
Multiplying further:
f(x) = (x^3 - 9x^2 - ix^2 + xi - 3x^2 + 27x + 3ix - 3xi - 27i - 3x + 27 + 3i)
Combining like terms:
f(x) = x^3 - (9 + i)x^2 - 3x^2 + (x - 3 - 3i)x + 27x + (27 + 3i)
Simplifying:
f(x) = x^3 - (12 + i)x^2 + (x - 3 - 2i)x + 27x + (27 + 3i)
The polynomial f(x) with real coefficients and the given zeros is:
f(x) = x^3 - (12 + i)x^2 + (x - 3 - 2i)x + 27x + (27 + 3i)

You are the new owner of a music shop in Greenwood. The previous owner
fled the city to join the circus as a magician. Your first duty as new owner
and store manager is to create an advertising plan based on the budget
available. You must figure out how many magazines and TV ads to
purchase.
TV ads cost $600 per airing.
Magazine ads cost $1200 per issue.
Your total advertising budget is $9,000.
1. If we let x = TV ads and y = magazine ads, write an inequality for our
advertising budget.
500 x + 1200y <= 9000
2. Due to space limitations, the magazine publishers tell us that we are only
allowed to purchase up to 6 magazine ads. Write an inequality for this
constraint. y<= 6
3. The television station called to say that we are only allowed to purchase
up to 7 TV ads. Write an inequality for this constraint.
X<=7

Use the points (1, 100) and (8, 800) to estimate the line of best fit.
1. Find the slope of the line.
2. Write the equation of the line.
3. What does the slope tell you about how each magazine ad affer
sales?
CD sales increased by about...?
1)
When the points (1, 150) and (6, 900) are used:
a)
Slope of line is 150.
Given points,
(1, 150) and (6, 900)
Slope of a line passing from two points:
Slope = y2 - y1 / x2 - x1
Slope = 900 - 150 / 6 - 1
Slope = 150
b)
Equation of line :
Y = mx + c
m = slope of line
c = y intercept
Here,
Slope =150
Hence the equation of line is:
y = 150x
c)
For every TV ad, CD sales increased by about 150 as the slope of line is + 150 which indicates the increase in sales of CD .
2)
When the points (1, 100) and (8, 800) ae used:
a)
Slope of line is 100.
Given points,
(1, 100) and (8, 800)
Slope of a line passing from two points:
Slope = y2 - y1 / x2 - x1
Slope = 800 - 100 / 8 - 1
Slope = 100
b)
Equation of line :
Y = mx + c
m = slope of line
c = y intercept
Here,
Slope =100
Hence the equation of line is:
y = 100x
c)
For every magazine ad, CD sales increased by about 100, as the slope of line is + 100 which indicates the increase in sales of CD .

How many inches are in 5 1/4 feet enter only a number
Answer:
64 inches.
Step-by-step explanation:
To find the amount of inches in 5 1/4 feet, you must first multiply 12 by 5 because there are 12 inches in one foot.
12x5=60.
The next step in order to complete the equation would be to find how many inches are in 1/4 of a foot.
To find how many inches are in 1/4 of a foot you must divide 12 by 4.
12 divided by 4= 4.
Now, you must as the two numbers together to get the total number of inches.
60+4=64.
This, 64 is your final answer.
Hope this helps! :)
