Answer:
The value is
Step-by-step explanation:
From the question we are told that
The null hypothesis is 
The level of significance is 
From the z table the critical value of
considering the two tails of the normal curve( This is because this a two tailed test ) is

Hence the critical value is
Answer:
5.36
Step-by-step explanation:
Given that:
<BAD = <CAE, therefore, BD = EC
Let's take x to be the length of BD = EC
BD + DE + EC = BC
BC = 20,
BD = EC = x
DE ≈ 9.28
Thus,
x + 9.28 + x = 20
x + x + 9.28 = 20
2x + 9.28 = 20
Subtract 9.28 from both sides
2x + 9.28 - 9.28 = 20 - 9.28
2x = 10.72
Divided both sides by 2 to solve for x



BD ≈ 5.36
Answer:
Hey
Step-by-step explanation:
Hey did you find the answers to this? i really need it. im desperate!
I'm pretty sure it is 5:55
To answer this question, simply input the values for g and h:
9/ (3) + 2 (6) + 5 = 9/ 3 + 12 + 5
= 9/ 20
Hope this helps!
