Answer:
I believe it's the third and fourth answers.
Step-by-step explanation:
Mean = 133.9
then calculate the z value
with z value you will find out the p value on a table.
if the p value is below .05 reject the null hypotheses
3x + 5x = 320
8x = 320
x = 40
3(40) : 5(40) = 120 : 200
The best answer would be Option C.
Answer:
D.(2,0) and (0,-4)
Step-by-step explanation:
A P E X approved.
1.) 8 to the second power which is 64 - 7
64-7=56
2.) 8(5-2) Parentheses first so 5-2=3
8x3=24
3.) 14 divided by 2= 7
4.) 5-8 divided by 4
-3 divided by 4= -0.75
Hope this helps!
