Answer:
The time required is 4.5 hours.
Step-by-step explanation:
A furniture manufacturing company typically takes 18 hours to assemble 12 pieces of furniture. To determine the number of pieces of furniture that will be assembled in 3 hours, the following calculations were proposed; the one that allows to verify this relationship correctly is
The 12 pieces of furniture assembled in 18 hours
So, 1 piece assembled in 18 / 12 hours = 1.5 hours
And 3 pieces assembled in 3 x 1.5 = 4.5 hours

it’s 2880 because if u multiply everything to get the area of both shoes then add it together that what u get
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
