The student made the mistake in Step 2.
It should be m∠o + m∠p = 180 (Supplementary angles)
If this is corrected, then, since m∠m + m∠n + m∠o = 180 from Step 1,
we have,
m∠m + m∠n + m∠o = m∠o + m∠p which is Step 3.
Cancelling m∠o both sides, we get,
m∠m + m∠n = m∠p which is Step 4.
I believe the correct answer would be A. The best correlation to use to measure the relationship between gender and grade point average for a group of college students would be the point-biserial correlation. It is coefficient that is used when a variable is dichotomous or that the variable is part of a whole set. It is used in measuring the direction of the correlation that is present between a dichotomous variable and a continuous variable. From the question, the dichotomous variable would be the grade point average for a group of college students while the other variable is the continuous one.

The system of equations provides a unique solution(one solution) at (-0.6, 1.6).
<h2>Given to us,</h2>
<h3>Equation 2</h3>
As we already have the value of y from equation 1, substitute its value in equation 2,
<h3>Equation 1,</h3>
substitute the value of x in equation 1,
As we can see the system of equations provides a unique solution(one solution) at (-0.6, 1.6).

Answer:
Step-by-step explanation:
<h3>Given inequality</h3>
The LHS is absolute value so we look at two options:
<h3>Option 1</h3>
5x + 3 is positive, then the inequality becomes:
- 5x + 3 < 2
- 5x < 2 - 3
- 5x < - 1
- x < - 1/5 or x < - 0.2
<h3>Option 2</h3>
5x + 3 is negative, then the inequality becomes:
- - (5x + 3) < 2
- 5x + 3 > - 2
- 5x > - 2 - 3
- 5x > - 5
- x > - 1
The solution is the combination of the two intervals:
- x > - 1 and x < - 0.2 ⇒ - 1 < x < - 0.2
Correct choice is B
