Answer:
b) B and D and c) A and C
Step-by-step explanation:
The hypotheses would be:

(Right tailed test at 5% level)
Sample proportions are
Sample A B C D
Success 31 34 27 38
Proportion p 0.775 0.85 0.675 0.95
Std error
(sqrtpq/n) 0.066 0.056 0.074 0.034
p diff
p-0.75 0.025 0.10 - 0.075 0.20
Z stat
p diff/SE 0.0757 1.77 1.01 5.80
p value 0.469 0.038 0.156 0.000001
we find that p value is more smaller than alpha, the more accurate the alternate hypothesis.
b) Only B and D provide against the null. Because p <0.05
c) A and C provide no evidence for the alternative because p >0.05
Answer:
A
Step-by-step explanation:
Let's try choice A.
y = -5x-4
(10, -52)
-52 = -5(10)-4
-52 = -50-4
-52= -54
-52 is not equal to -54, so A is the answer.
The distance he travels is 6+8=14 blocks. the straight line distance is the hypotenuse of a right triangle with legs 8 and 6.
6²+8³=c²
36+64=c²
100=c²
c= √100 = 10 blocks.

Step-by-step explanation:
Answer:
x ≥ –24
Step-by-step explanation:
Multiply both sides of it by 4:
4(x/4) ≥ 4(-6)
x ≥ -24
