120= 2(w+20) + 2w
120= 2w+40+2w
120= 40+4w
80=4w
w=20
Length:
w+20
20+20
40
Width: 20
So the dimensions are:
Length is 40
Width is 20

L+l+L+l=120
L+l=60

L=l+20 so l+20+l=60, 2l=40, l=20, L=40

The dimensions are 20 wide, 40 long.

The u.s. dairy industry wants to estimate the mean yearly milk consumption. a sample of 16 people reveals the mean yearly consum
lidiya [134]
1-2. The best estimate for the population mean would be sample mean of 60 gallons. Since we know that the sample mean is the best point of estimate. Since sample size n=16 is less than 25, we use the t distribution. Assume population from normal distribution.

3. Given a=0.1, the t (0.05, df = n – 1 = 15)=1.75

4. xbar ± t*s/vn = 60 ± 1.75*20/4 = ( 51.25, 68.75)

5. Since the interval include 63, it is reasonable.
