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
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.

Answer:
The amount of money they will spend at the restaurant is $35.16
Step-by-step explanation:
From the information given in the question, we have;
The amount Jessica, Genesis, and Violet received as bill at the restaurant, X = $29.30
The amount they wished to leave as tip, T = 20% (of the bill)
Therefore, the amount of money they will spend at the restaurant, 'A', is given as follows;
A = X + T
T = 20% of X = 20/100 × X = 0.2·X
∴ A = X + 0.2·X = 1.2·X
X = $29.30
A = 1.2·X = 1.2 × $29.30 = $35.16
The amount of money they will spend at the restaurant, A = $35.16

The Value of y in the equation 2y-2=16 is?
Answer:
9
Step-by-step explanation:
To answer this question, you must isolate the variable y.
Step 1.
add 2 to each side to isolate 2y
2y-2+2=16+2
the twos on the left cancel out and you are left with: 2y=18
Step 2.
divide each side by 2 to isolate y completely
2y/2=18/2
y=9
help? i don’t understand this
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

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°

For your last event of the day, you are going to purchase tickets to watch Patrick perform. They are charging people by the minute. They charge $1 per minute to watch the show and in addition, there is also a processing fee that you must pay if $10. Why would the total cost be if you attended the concert for 20 minutes
Answer:
$30
Step-by-step explanation:
Given that they charge $1 per minute to watch the show and in addition, there is also a processing fee that you must pay if $10, to attend the show for 20 minutes, it means that the total fee to be paid will be the sum of the product of 20 and $1 and the processing fee of $10
= (20 * $1) + $10
= $20 + $10
= $30

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.

??????????????helpppp
answer is 25
Step-by-step explanation:
for something like this you need to use the law of sins. First identify all the angles. There is a 90 degree angle and a 59 degree angle and those are clear. the missing angle is = 59 + 90 = 149
since a triangle has 180 degrees in total you say 180 - 149 = 31. the missing angle is 31 degrees. so we give the angles names. angle with 59 degrees will be angle A, 90 will be B and 31 will be C. So now we just give the sides names. let's replace that x with an a since it's across angle A. the side along angle B will be named b and the side along angle C will be named c. so you say:
Sin A/ a (sin A over a) = Sin B/b = Sin C/c
Sin A is what we are looking for so we say
59 degrees over/ x = sin 31 degrees/ 13 (we leave out the 90 degrees since we don't know the side and also we are not interested in it)
now we do cross multiplying.
say x ×sin 31 degrees = 13× sin 59
now divide these by sin 31
x = 13 × sin 59 ÷ 31 = 25

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
