According to a U.S. news poll, 38% of students in the class of 2013 had done an internship during their time as an undergraduate student. Dana is interested in finding out whether students at her university had an internship rate that was higher than the national average. She obtained a list of 25 randomly selected students from the population of all students at her university by requesting this information from the university’s institutional research office. She collected the responses and calculated that the proportion for her university was 43%. Which one of the following statements about the z-test is correct?
It is not safe to use the z-test for p, since the sample is not a random sample from the entire population (or cannot be considered as one).
It is not safe to use the z-test for p, since n * (1 ? po) is not large enough.

A national poll by the Institute for College Access and Success showed that in 69% of college graduates from public and nonprofit colleges in 2013 had student loan debt. Dr. Blackman wanted to find out if her public nonprofit university had a lower proportion of students who graduated with student loan debt in 2013.
For this survey, the null hypothesis was that the proportion of students with graduated with student loan debt equals 69% and the alternative hypothesis is that the proportion with student loan debt does not equal 69%. The significance level for this test was 0.05.
The results of the hypothesis test of the new survey showed a p-value of 0.039.

D. [tex]-\frac{\sqrt{2} }{2}[/tex]
Step-by-step explanation:
So, on a regular coordinate plane, coordinates are written (x,y)
well, in trig, coordinates are written (cosθ, sinθ).
if sinθ=[tex]\frac{\sqrt{2} }{2}[/tex] in the second quadrant, then look for the "y-value" that says
if you don't have a unit circle to look at, then it helps to know that the fraction [tex]\frac{\sqrt{2} }{2}[/tex] is ONLY found with ITSELF OR THE NEGATIVE OF ITSELF. it is never paired with another number.
this means that this number will only be seen in the coordinates
[tex](\frac{\sqrt{2} }{2} ,\frac{\sqrt{2} }{2})\\(-\frac{\sqrt{2} }{2},\frac{\sqrt{2} }{2})\\(-\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})\\(\frac{\sqrt{2} }{2},-\frac{\sqrt{2} }{2})[/tex]

39. Make Sense and Persevere A company
manufactures cell phone cases. The length
of a certain case must be within 0.25 mm of
125 mm, as shown (figure is not to scale). All
cases with lengths outside of this range are
removed from the inventory. How could you
use an absolute value inequality to represent
the lengths of all the cases that should be
removed? Explain.
Answers
An absolute value inequality is used to represent the situation given that
cases with values above and below the allowance are to be removed.
The absolute value inequality for the situation is; |x - 125| ≥ 0.25.Reason:
The given parameter are;
Length of a case x ≤ 125 + 0.25
Length of a case x ≥ 125 - 0.25
Required:
Represent the cases that are to be removed using absolute inequality.
Solution:
The given inequalities sign can be rearranged to give the cases to be
removed as follows;
x ≥ 125 + 0.25
∴ x - 125 ≥ 0.25...(1)
x ≤ 125 - 0.25
x - 125 ≤ -0.25
Multiplying both sides by (-1) gives;
-1×(x - 125) ≥ (-1) × -0.25 = 0.25
-(x - 125) ≥ 0.25...(2)
Therefore;
The given that a case with difference (x - 125) ≥ 0.25 or when (x - 125) is
negative -(x - 125) ≥ 0.25 should be removed, using absolute inequality, we
have;
|x - 125| = (x - 125) when x > 125
|x - 125| = -(x - 125) when x < 125, and (x - 125) is negative
Which gives; A case with length |x - 125| ≥ 0.25 should be removed.
The absolute value inequality that represents the lengths of all the cases
that should removed is therefore;
|x - 125| ≥ 0.25Learn more here:

what is the equation

to y=3/4x+12 that passes
through (12,3)
Answers
Answer:
y = -4/3 x + 19
Step-by-step explanation:
y = 3/4x + 12
Slope of this line = 3/4 and the slope of the perpendicular line: - 4/3
Point: (12,3)
y-intercept: 3 - (- 4/3)(12) = 3 + 16 = 19
y = - 4/3x + 19
Tia received $7.55 in change in quarters and dimes. There
were 38 coins in all. How many of each kind did she
receive?
Answers
Answer: 25 quarters and 13 dimes
Step 1: Setup Coin Value and Coin Total Equation:
Coin Value Equation → 0.1d + 0.25q = $7.55 where d = dimes and q = quarters
Coin Total Equation → d + q = 38
Step 2: Rearrange Coin Total Equation in terms of dimes (d)
d = 38 - q ← Revised Coin Total Equation
Step 3: Plug in our Revised Coin Total Equation for d into our Coin Value Equation:
0.1(38 - q) + 0.25q = $7.55
0.1(38) - 0.1(q) + 0.25q = $7.55
3.8 - 0.1q + 0.25q = $7.55
3.8 + (0.25 - 0.1)q = $7.55
3.8 + 0.15q = $7.55
Step 4: Subtract 3.8 from each side of the equation to isolate q
3.8 - 3.8 + 0.15q = $7.55 - 3.8
0.15q = 3.75
Step 5: Divide each side of the equation by 0.15 to isolate q
0.15q/0.15 = 3.75 /0.15
q = 25
Step 6: Using our value for q, Solve for d using our Coin Total Equation:
d + 25 = 38
Subtracting 25 from both sides, we get d + 25 - 25 = 38 - 25
d = 13
Summarizing our word problem, we see that 25 quarters and 13 dimes add up to $7.55

Answer: There is no graph that I can see. I created one showing each line.
Step-by-step explanation: A straight line has the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x is zero). The two lines with slope 25 will rise much more quickly than the ones with a slope of 5. You could eliminate two lines based on that alone. With the two remaining lines, look at the y-intercept seen on the graph (the value of y when x=0). The options are 5 and -5. The correct line will be the one with the expected intercept.

Do both points satisfy this equation?:
(1,-2): -2 = -1 -1 Yes
(-3,2): 2 = -(-3)-1 [or 3-1=2] Yes
The line contains the points (1,-2) and (-3,2) is Y= -x-1. The correct option is B.
What is coordinate geometry?A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
