Answer:
Area of a trapezoid:
A=h(a+b)/2
A=2xy(4x^2y+7x^2y)/2
A=2xy(11x^2y)/2
A=22x^3y^2/2
A=11x^3y^2
So, the correct answer is the third option: A=11x^3y^2

The campus bookstore at a local university is interested in finding out whether the textbook preference and the class level (freshman, sophomore, junior, senior) of the student are associated. A random sample of 100 students is obtained, and each student in the sample is asked which textbook he or she prefers: new books, used books, or digital books. The students are also asked whether their class level is freshman, sophomore, junior, or senior.Which of the following is the appropriate test for the investigation?A. A one-sample tt-test for a population meanB. A two-sample tt-test for a difference between meansC. A chi-square goodness-of-fit testD. A chi-square test of homogeneityE. A chi-square test of independence
Answer:
The appropriate test for the investigation is;
E. A chi-square test of independence
Step-by-step explanation:
The chi-square test for independence is for the analysis of two categories from within a population to evaluate the existence of association among the different categories within the two variables
The chi-square test for independence is used for the analysis of contingency (frequency) table
Therefore, the appropriate test for the investigation in finding out (1) the textbook preference and (2) the class level of the associated student is the chi-square test of independence

Step-by-step explanation:
Twice the difference of a number and 2 is 7.
Answer:
9
Step-by-step explanation:
-Twice means muliply by 2
-The difference of a number and 7 means subtract a number/variable and 7.
-Is equal to 9 means =9
2(X - 7) = 9
An equation to model the number is: n - 7 x 2 = 2
To find the equation, break apart the question.
twice the difference of a number and 7 equals 2. - "Twice" means we are multiplying by 2, or x 2
twice the difference of a number and 7 equals 2. "The difference of a number and 7" means we are subtracting n - 7, and this is being multiplied by 2 so we have n - 7 x 2 so far.
twice the difference of a number and 7 equals 2. "Equals two" means the equation is equal to 2, or = 2, so our equation is n - 7 x 2 = 2.
How many ways can you write one whole as a fraction
Answer:
infinite
Step-by-step explanation:

Emily’s lawn grows at a constant rate. The height of her lawn, during a 10-day period, is represented by the graph below.
Based on the graph, after how many days will the lawn be 12 centimeters in height?
A) 8 days
B) 10 days
C) 16 days
D) 24 days
Answer:
I think the answer would be C 16 days.
I cant really see the bottom of the graph
Step-by-step explanation:
In 16 days Emily's lawn will achieve a height of 12 centimeters. option C is correct.
Given that,
Emily’s lawn grows at a constant rate. The height of her lawn, during a 10-day period. Based on the graph, after how many days will the lawn be 12 centimeters in height is to be determined.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The slope of the graph = Δy/Δx = 1 / 2
Now,
Equation of the height of the lawn,
y - 4 = 1/2(x)
y = 1/2x + 4
Now, for y = 12
12 = 1/2x + 4
x/2 = 8
x = 8 * 2
x = 16
Thus, In 16 days Emily's lawn will achieve a height of 12 centimeters. Option C is correct.

Answer:
I believe the answer is - 2/5 (negative two-fifths).
Step-by-step explanation:
First, you see if the answer is positive or negative:
Since the line is going up from right to left (the bottom arrow is on the right, top arrow is on the left), this means the slope will be negative. A line that looks like this is always negative.
Now we calculate the slope:
The formula to find slope is rise/run (rise over run). Since this is the formula, you need to find the rise first. Start at the point on the 4th Quadrant. Notice the dark blue line is going straight through the point. Then notice the part where the line goes through in the top part of the arrow (the 2nd Quadrant). Count the units up (rise) on the line in the 4th Quadrant until they vertically are congruent, or count 4 units up. Then count to the left (run) until you meet the other dark blue line in the 2nd Quartile, or count 10 units to the left. Now you make the fraction 4/10, but since this is a negative slope, the answer is - 4/10.
But don't forget! You always need to remember (if necessary) to simplify!!
- 4/10 = - 2/5
I hope this wasn't too confusing and helped you out :)

A ramp 23ft long rises to a platform. The bottom of the platform is 11ft from the foot of the ramp. Find x, the angle of elevation of the ramp. Round your answer to the nearest tenth of a degree.
Answer:
61.4°
Step-by-step explanation
Given
Length of the ramp = 23ft = hypotenuse
Base of the ramp = 11ft = Adjacent
Required
Angle of elevation x
Using the SOH CAH TOA identity
Cos theta =adj/hyp
Cos x = 11/23
Cos x = 0.4782
x = arccos0.4782
x = 61.42°
Hence the angle of elevation is 61.4°

Mandy spent $287 on 7 pairs of shoes. She purchased some pairs of boots that cost $65 per pair and some pairs of workout shoes that cost
S23 per pair
Use a system of equations to help you identify how many pairs of boots (b) and workout shoes (w) Mandy bought
Enter the number of pairs of boots and workout shoes Mandy bought
Answer: Boots = 3
workout shoes = 4
Step-by-step explanation:
boots cost $65 so 65 x 3 = 195
and workout shoes cost $23 so 23 + 4 = 92 then 195 + 92 = 287

Jesse sells advertising pages for a magazine. He is paid a 13.5% commission for each page he sells. A page sells for $1,350. He sold an average of 24 pages a month. What was his commission for the year?
Answer:
$52,488
Step-by-step explanation:
The computation of the commission for the year is as follows:
It is given that a 13.5% commission is to be paid for each page that he sold
Here the page sold for $1,350
And, he sold average of 24 pages a month
So his commission for the year is
= $1,350 × 24 × 12 × 13.5%
= $52,488

A rectangle is a parallelogram. What is true of the diagonals of a rectangle
that is not true of the diagonals of a parallelogram, in general?
Answer:diagonals of rectangle are equal in length while diagonals of a parallelogram can be different lengths
Step-by-step explanation:
What is true of a rectangle that is not true of a parallelogram is that; the diagonals of a rectangle are equal but the diagonals of a parallelogram are not equal.
We are dealing with rectangles and parallelogram here.
Now, both rectangle and parallelogram have 4 sides respectively with 2 of the sides being equal.
Now, for a rectangle, the diagonals are always equal because all the internal angles are equal.
However, for a parallelogram, all the internal angles are not equal and as such the diagonals are also not equal.
In conclusion, what is true of a rectangle that is not true of a parallelogram is that the diagonals of a rectangle are equal but the diagonals of a parallelogram are not equal.

Answer:
Step-by-step explanation:
c(f) = [tex]\frac{5}{9}(f-32)[/tex]
[tex]-21 = \frac{5}{9}(f-32)[/tex]
Multiply both sides by 9
-21*9 = 5(f - 32)
-189 = 5*f - 5*32
-189 = 5f - 160
Add 160 to both sides
-189 + 160 = 5f
-29 = 5f
Divide both sides by 5
-29/5 = f
f = -5.8
f = -6 °C
