find the area of the given figure.
A)792in^2
B)464in^2
C)242in^2
D)358in^2
E)94in^2
Answers
Answer: C. 242
Step-by-step explanation:
So first you need to know the formulas for the shapes (trapezoid and rectangle) to solve it.
Trapezoid- A= 1/2(b1+b2)h
Rectangle- L x W.
So to plug in numbers for trapezoid should look like: 1/2(13+24) (4)
1/2 (37) (4)
(18.5) (4)
=74.
For rectangle: 7 x 24= 168.
So add them together and you should have your answer. 168+74=242 in.

The conditional relative frequency table below was generated by column using frequency table data comparing the number of calories in a meal to whether the meal was prepared at home or at a restaurant.
A 4-column table with 3 rows titled number of calories and location of meal preparation. The first column has no label with entries greater than or equal to 500 calories, less than 500 calories, total. The second column is labeled home with entries 0.15, 0.85,1.0. The third column is labeled restaurant with entries 0.55, 0.45, 1.0. The fourth column is labeled total with entries 0.28, 0.72, 1.0.
A nutritionist attempts to determine an association between where food is prepared and the number of calories the food contains. Which is most likely true?
An association cannot be determined because the value 0.55 is similar to the value 0.45.
There is an association because the value 0.15 is not similar to the value 0.55.
There is an association because the sum of each column is 1.0.
An association cannot be determined because the sum of the rows going across is not 1.0.
Answers
There is an association because the value 0.15 is not similar to the value 0.55
For the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.
The conditions that satisfy whether there exists an association between conditional relative frequencies are:
1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.
2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.
For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45
We can conclude that there is an association because the value 0.15 is not similar to the value 0.55

Michael purchased a chocolate swirl yogurt in a waffle cone. The yogurt cost $1.25 and the waffle cone was 50¢. He gave the clerk 8 quarters. How much did she give back to Michael?
Answers
Answer:
Michael should get $0.25 from the clerk.
Step-by-step explanation:
Add $1.25+$0.50 together which equals $1.75 and multiply $0.25x8 which equals $2.00 and subtract $1.75 from $2.00 and that equals $0.25.
Answer:
.25 = 1 quarter
Step-by-step explanation:
8 x .25 = $2.00
1.25 + .50 = $1.75
2.00 - 1.75 = .25

Hope it helped! (:
Answer:
The perimeter of the rug is 22.
Step-by-step explanation:
The formula for perimeter of a rectangle is side + side + side + side .
The width of the rug is 4 and the length of the rug is 7.
And 4 + 4 + 7 + 7 = 22.

170 students
Answers
Answer: 163 students
Step-by-step explanation:
First find the percentage of students who were in favor of having school start one hour later based on the sample of 20 students.
= 13/20 * 100%
= 65%
The apply this percentage to the total number of students in school to find your answer:
= 65% * 250 students
= 162.5
= 163 students
The number of students in the school who are in favor of having school start one hour later is; C: 163 students
What is the random sample?We are told that 13 out of the 20 surveyed students were in favour of having school start one hour later. Thus;
Probability = 13/20 * 100% = 65%
Now, the school has 250 students and as such, the number of students in the school who are in favor of having school start one hour later is;
65% * 250 students = 162.5 ≈ 163 students

Jordan is a sixth-grade student. He created one data set by recording the ages of all the students in his classes. He created a second data set by recording the ages of all his teachers. Which data set would you expect to have the greater mean absolute deviation? Why?
Answers
Answer:
Second Data Set
Step-by-step explanation:
The mean absolute deviation describes the average distance between each data point. Let's consider both data sets. In data set one, classmate ages are recorded. Because most of Jordan's classmates are close together in age, the amount of deviation is small. In data set two, teach ages are recorded. Because teacher's ages can range from 23-99, the deviation in this set is expected to be larger than set one.

4²+b² = 5²
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem to find the length of the missing side.
The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse. Algebraically, this is represented as
a²+b² = c²
We have the measure of one leg, 4 in. We also have the measure of the hypotenuse, 5 in. This gives us
4²+b² = 5²

Answer:
16π (units squared)
Step-by-step explanation:
Picture a full circle with radius 8. The area of this full circle is A = πr².

Now multiply this result by 1/4 to obtain the area of the figure shown:
A = (1/4)64π = 16π (units squared)
When p(x)=2x^4+kx+1 is divided by x+1, the remainder is the same as when q(x)=3x^4+kx^2+2 iis divided by x-1. Find k
Answers
Answer:
k = -1
Step-by-step explanation:
Here, we want to get the value of k
Now, to get the remainders, we set the linear factors to zero, solve for x and insert the value of x into the polynomial
for x + 1 = 0
x= -1
insert -1 into p(x)
we have this as;
2(-1)^4 + k(-1) + 1
= 2 - k + 1 = 3-k
for the second
set x-1 to zero
x = 1
insert into q(x)
q(1) = 3(1)^4 + k(1)^2 + 2
= 5 + k
so we can now equate the two remainders;
5 + k = 3-k
k + k = 3-5
2k = -2
k = -2/2
k = -1
