Which line contains the points (1,-2) and (-3,2)?
A. Y= -x+1
B. Y= -x-1
C. Y= 1/2x-1
D. Y= -1/2x+1
Answer: y = -x1 - 1
Step-by-step explanation:
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.
Given that the points are (1,-2) and (-3,2). The equation of the line will be the line which satisfies the given points.
Y= -x-1
At points (1,-2),
Y= -x-1
-2=-1-2
-2=-2
At point(-3,2).
Y =-x-1
2=3-1
2 = 2
The line Y= -x-1 is passing through the points (1,-2) and (-3,2). The correct option is B.

Tia received $7.55 in change in quarters and dimes. There
were 38 coins in all. How many of each kind did she
receive?
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

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).

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.
Which of the following statements is correct? Check all that apply.
The results were statistically significant.
The results were not statistically significant.
The null hypothesis should be rejected.
The null hypothesis should be accepted.
The null hypothesis cannot be rejected.
Answer: The null hypothesis should be accepted and The results were not statistically significant

Answer:
See below.
Step-by-step explanation:
Since there is an equal sign, this is not an expression. It is an equation. If you evaluate the right side, you'll see that it is a false equation since both sides are not equal to each other. Also, there is a bracket missing.
90 is not equal to 4.55.
Maybe it is meant to be the following expression:
90 + [(82 - 77).91] = 90 + 5(0.91) = 90 + 4.55 = 4.55
Or maybe this one:
90 - [(82 - 77).91] = 90 - 5(0.91) = 90 - 4.55 = 85.45

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.
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:

the slope between two points can be defined as the change in y over the change in x. Consider (0, 11) as your first point and (1,4) as your second point.
To find the slope, do:
(y2 - y1) / (x2 - x1) = slope
