Answer:
13/20
Step-by-step explanation:
. It takes 11 widgets to assemble one motor. Your team can assemble four motors in one day. If you need to order parts for next week (5 working days), how many widgets should you order?
Number of widgets needed to make one motor = 11
Number of motors made each day = 4
Number of widgets used per day :-
= 4 × 11
= 44 widgets
Number of widgets I need to order for the next five days of the upcoming week :-
= 44 × 5
= 220 widgets
Therefore , my team should order 220 widgets for the next week ( 5 working days ) .
Answer:
Your answer should be 220 widgets
Step-by-step explanation:
Becasue if you have 11 in one motor and you build four a day then multiply 4 and 11 to get 44. Then you see that you get 44 widgets in a day you multiply 44 by the number of working days which is 5. So after multiplying you get 220 widgets per week.

Jacob is a construction worker who earns a yearly income given by the expression 2000x + 3000, where x is the number of hours he works each week. Carlos works with Jacob and earns a yearly income given by the expression 3800x – 40000. A manager predicts that if Carlos and Jacob each work 35 hours, they will earn the same amount of money.
PART A:The number of hours that makes the equation true is
Options: 24, 27, 29,31,34
PART B:Round your answer to the nearest whole number. The manager's prediction is
Options: equal to, less than, greater than
the actual number of hours that Carlos and Jacob need to work to earn the same amount of money.
Answer:
[tex]x = 24[/tex]
24 is less than 35
Step-by-step explanation:
Given
Jacob: 2000x + 3000
Carlos: 3800x - 40000
Solving (a):
To solve (a), we need to equate both expressions;
[tex]3800x - 40000 = 2000x + 3000[/tex]
Collect Like Terms
[tex]3800x - 2000x = 40000 + 3000[/tex]
[tex]1800x = 43000[/tex]
Solve for x
[tex]x = 43000/1800[/tex]
[tex]x = 24[/tex] --- Approximated
Solving (b);
The manager's prediction is 35 hours.
And the actual hours is 24.
By comparison;
24 is less than 35

The reciprocal of - 4 3/4 is
Answer:
-4/19
Step-by-step explanation:
1. The first step to finding the reciprocal of -4 3/4 is to convert it into an improper fraction. To do that, multiply the -4 by the denominator, 4, and add the answer to the numerator, 3. The answer should come out to -19/4.
2. Now we have to find the reciprocal of -19/4 by flipping the denominator with the numerator, which is -4/19.

There are 20 circles and 12 triangles. What is the simplest ratio of triangles to total shapes
Answer:
3:8
Step-by-step explanation:
You can divide both numbers by 4, that gets you to your simplest ratio. :)
The ratio of the triangles to the total shape will be equal to 3: 8.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
For instance, if there is 1 boy and 3 girls, you may express the ratio as 1: 3 (there are 3 girls for every boy), meaning that there are 1 in 4 boys and 3 in 4 girls.
Given that there are 20 circles and 12 triangles. The ratio will be calculated as,
Ratio = triangles / total shape
Ratio = 12 / ( 20+ 12 )
Ratio = 12 / 32
Ratio = 3 / 8
Therefore, the ratio of the triangles to the total shape will be equal to 3: 8.

The coordinates of point T are (0,6). The midpoint of ST is (4.-6). Find the coordinates
point S.
Answer:
The coordinates of endpoint S are [tex]S(x,y) = (8,-18)[/tex].
Step-by-step explanation:
Let [tex]T(x, y) = (0, 6)[/tex] and [tex]M(x,y) = (4,-6)[/tex], which is the midpoint of line segment ST. From Linear Algebra we get that midpoint is the following vector sum of endpoints S and T. That is:
[tex]M(x,y) = \frac{1}{2}\cdot S(x,y) + \frac{1}{2}\cdot T(x,y)[/tex] (Eq. 1)
Now clear S in the previous expression:
[tex]S(x,y) = 2\cdot M(x,y) - T(x,y)[/tex] (Eq. 1b)
Then, the coordinates of point S are:
[tex]S(x,y) = 2\cdot (4,-6) - (0,6)[/tex]
[tex]S(x,y) = (8, -18)[/tex]
The coordinates of endpoint S are [tex]S(x,y) = (8,-18)[/tex].

In how many different ways can a ski club consisting of 15 people selected a team for national championship? There are 4 spots available on the team going to national championship.
Answer:
Step-by-step explanation:
Combination has to selection. When selecting 4 people out of a pool of 15 people, this can be done as thus according to combination formuka:
15C4 = 15!/(15-4)!4!
15C4 = 15!/11!4!
15C4 = 15*14*13*12*11!/11!*4*3*2
15C4 = 15*14*13*12/24
15C4 = 32760/24
15C4 = 1365 different ways.
Hence this can be done in 1365 different ways
Salty's Surf Shop loses $35,000 during cold, rainy summers and profits $175,000 during summers that
are hot and dry. The probability that it will be hot and dry during summers is 30%. What is the expected
profit Salty would realize over 10 years?
Answer:
$280,000
Step-by-step explanation:
Given that:
Loss during cold = $35000
P(hot and dry) = 30% = 0.3
Hence ; P(cold) = 1 - 0.3 = 0.7
Profit during hot and dry= $175,000
Expected profit over 10 years =?
________Hot & Dry __________ Cold __
X : _______ 175,000 ________ -35,000
P(X) : _______ 0.3 ____________ 0.7
Expected probability (E(X)) = Σx*p(x)
= 0.3(175,000) + 0.7(-35,000)
= 52,500 + (-24,500)

The cost for a sample of 9 cars, in hundreds of dollars, is provided below: 10,6,8,10,4,3.5,7.5,8,9 (a) What is the median cost of the total damage suffered for this sample of cars? (b) What is the first quartile for the above data? (c) What is the interquartile range of the above data? (d) What is the mean of the total damage suffered for this sample of cars? (e) Using the correct units, what is the value of the variance?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the cost data: 10,6,8,10,4,3.5,7.5,8,9
A.) Median cost :
Sorted data:
3.5, 4, 6, 7.5, 8, 8, 9, 10, 10
0.5(n + 1)th term ; n = number of samples
0.5(9 + 1)th term
= 0.5(10)th term = 5th term
Median = 5th term = 8
B.) First quartile (Q1) :
0.25(n + 1)th term ; n = number of samples
0.25(9 + 1)th term
= 0.25(10)th term = 2.5th term
Q1 = (2nd term + 3rd term) / 2 = (4+6)/2 = 10/2 = 5
Q1 = 5
C.) interquartile range = (Q3 - Q1)
Q3 = 0.75(n + 1)th term ; n = number of samples
0.75(9 + 1)th term
= 0.75(10)th term = 7.5th term
Q3 = (7th term + 8th term) / 2 = (9+10)/2 = 19/2 = 9.5
Q3 = 9.5
Q3 - Q1 = (9.5 - 5) = 4.5
D.) Mean (μ) :
μ = ΣX / n
n = sample size
μ =(10+ 6 + 8 + 10+ 4 + 3.5 + 7.5 + 8 + 9) / 9
μ = 66 / 9
μ = 7.33
3.) Population variance (s²)
Σ(x - μ)² / n - 1
=[(10 - 7.33)^2 + (6 - 7.33)^2 + (8 - 7.33)^2 + (10 - 7.33)^2 + (4 - 7.33)^2 + (3.5 - 7.33)^2 + (7.5 - 7.33)^2 + (8 - 7.33)^2 + (9 - 7.33)^2] / 9
= 45.5001 / 8
