Answer:
96
Step-by-step explanation:
From the given information:
At 95% Confidence interval level,Level of significance
0.05, the value of Z from the standard normal tables = 1.96
Margin of Error = 0.10
Let assume that the estimated proportion = 0.5
therefore; the sample size n can be determined by using the formula: 


n = 96.04
n
96
Answer:
For an equation such as y = 2.6x, the slope is the unit rate, which is the coefficient of x. For a table, <u>the change in y divided by the change in x</u> is the unit rate, or slope.
Answer:
in 45-45-90 triangle side opposite to 90 is a√2
Step-by-step explanation:
so the answer is C.3√2
put a=3
I don't know if you need the average but i did 21 divided by 9 and got 2.333
L=w+9
p=2w+2l
p=2w+2*(w+9)
p=2w+2w+2*9
p=4w+18
4w+18=38
4w=38-18
4w=20
w=20:4
w=5 in
l=5+9=14 in
