We have three pairs of rectangles:
16ft × 6ft = 96ft²
2ft × 6ft = 12ft²
2ft × 16ft = 32ft²
S.A. = 2 × (96 + 12 + 32) = 2 × 140 = 280ft².
<h3>Answer: C.) 280ft²</h3>

Answer:
So the answer for this case would be n=16 rounded up to the nearest integer
Step-by-step explanation:
For this case we have the following info given:
represent the population deviation
represent the margin of error desired
The margin of error for the true mean is given by this formula:
(a)
And on this case we have that ME =0.03 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The confidence level is 80%, the significance would be and the critical value for this case is , replacing into formula (b) we got:
So the answer for this case would be n=16 rounded up to the nearest integer
Step-by-step explanation:
just put the ratios into a fraction if x:y then x/y
A.)6/1=6
B.)12/2=6
C.)4/24=1/6
D.)48/8=6
E.)18/3=6
F.)1/6
24/4=6 so A, B, D, and E are equivilant to the ratio 24/4
