Conceptual Set 1. The same researcher wants to then compare the final (time 2) levels of anger in this experimental group to a c

ontrol group that just had the water balloons thrown at them. He compares the group from the previous questions to a group who did not do pushups. Which t-test should he use?
QUESTION 55-Conceptual Set 1. Why should the researcher from question 54 use that test?


A.Because single sample t-tests compare a sample mean to a population mean, which is what the researcher is attempting to do
B. Because single sample t-tests compare scores before and after an event, which is what the researcher isattempting to do
C. Because single sample t-tests compare two completely different groups in a sample, which is what the researcher is attempting to do
D. Because paired samples t-tests compare a sample mean to a population mean, which is what the researcher is attempting to do
E. Because paired samples t-tests compare scores before and after an event, which is what the researcher is attempting to do
F. Because paired samples t-tests compare two completely different groups in a sample, which is what the researcher is attempting to do
G. Because independent sample t-tests compare a sample mean to a population mean, which is what the researcher is attempting to do
H. Because independent sample t-tests compare scores before and after an event, which is what the researcher is attempting to do
I. Because independent sample t-tests compare two completely different groups in a sample, which is what the researcher is attempting to doA

What is the value of tan x°?
dmitriy555 [2]
Hi there!

\tan(x)  =  \frac{opposite \: side}{adjecent \: side}
\tan(x)  =  \frac{8}{6}
\tan(x)  = 1 \frac{1}{3}

x = 53.1
Therefore tan x° = 1 1/3 and x = 53.1°

For ΔABC, ∠A = 8x - 10, ∠B = 10x - 40, and ∠C = 3x + 20. If ΔABC undergoes a dilation by a scale factor of 1 2 to create ΔA'B'C'
STALIN [3.7K]
If the triangles ABC and A'B'C' are similar, then 
angle A = angle A'
8x-10 = 6x+10
8x-6x = 10+10
2x = 20
x = 20/2
x = 10

So angle A is
angle A = 8x-10
angle A = 8*10-10
angle A = 80-10
angle A = 70
making that the measure of angle A' as well

This is why the answer is choice A
