Answer: 505
Step-by-step explanation:
The formula to find the sample size n , if the prior estimate of the population proportion (p) is known:
, where E= margin of error and z = Critical z-value.
Let p be the population proportion of crashes.
Prior sample size = 250
No. of people experience computer crashes = 75
Prior proportion of crashes 
E= 0.04
From z-table , the z-value corresponding to 95% confidence interval = z=1.96
Required sample size will be :
(Substitute all the values in the above formula)
(Rounded to the next integer.)
∴ Required sample size = 505
B(5 - 2, -6 + 3, -1 + 1) = B(3, -3, 0)
Answer:
option B
Step-by-step explanation:
let the height=x
base=x
Area=½bh
72=½x•x
72×2=x²
144=x²
x=√144=12
Answer:
