P = 2l + 2w
p - 2w = 2l
l = p-2w/2
It would be the third response
Answer:
256x * 16
Step-by-step explanation:
(4x * 4x * 4) * (4x * 4x * 4 )
(16x * 4 ) * ( 16x *4)
16x * 16x = 256x
4 * 4 = 16
256x * 16
hope this helped a little
* = multiply
Answer:
The interval from the sample of size 400 will be approximately <u>One -half as wide</u> as the interval from the sample of size 100
Step-by-step explanation:
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally from the normal distribution table the critical value of
is
Generally the 95% confidence interval is dependent on the value of the margin of error at a constant sample mean or sample proportion
Generally the margin of error is mathematically represented as
Here assume that
is constant so

=> 
=> 
So let
and 
=> 
=> 
=> 
So From this we see that the confidence interval for a sample size of 400 will be half that with a sample size of 100
