Answer:
B would be (-1, -2)
C would be (-1, 1)
A would be (-4, -2)
Step-by-step explanation:
The ordered pairs are affected by the y value. The X value stays the same since you didn't move the shape any to the right or left. The y values went down three on all of the points because you moved the whole shape down three spots.

Answer:
p= 0.9995 and we can conclude that students receiving aid is more than 50% according to the sample results in 2% significance level.
Step-by-step explanation:
: less than or equal 50% of students at his college receive financial aid
: more than 50% of students receive financial aid.
According to the nul hypothesis we assume a normal distribution with proportion 50%.
z-score of sample proportion can be calculated using the formula:
z=
where
- X is the sample proportion (0.65)
- M is the null hypothesis proportion (0.5)
- s is the standard deviation of the sample (
) - N is the sample size (120)
then z=
≈ 3,29
thus p= 0.9995 and since p<0.02 (2%), we reject the null hypothesis.
-8y = -2x + 16
y = 1/4x - 2
y = 1/4x + 3
5/18 because 2 (1/2) is equal to 1 then dividing the number means to turn it around so 18/5 will be 5:18
1) -512, 1024, -2048. You just multiply by -2.
2)7.8125, -3.9062, 1.9531. You divide by -2
