The largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'
<h3>
Scale drawing</h3>
Scale drawing involves drawing a drawing in a different size and dimension that is proportional to the original dimension
<h3>Dimensions</h3>
The dimensions of the design for the farm scene painting is given as:
The dimensions of the wall is given as:
Convert feet to inches
Divide the dimensions of the wall by the painting to get the scale ratios (k)
Also, we have:
Remove decimal (do not approximate)
By comparison;
21 is less than 24
Multiply 21 by the dimensions of the painting
So, we have:
Hence, the largest possible complete design that can be painted on a 24’ x 16’ wall is 252' by 189'

Answer:
a.) 60
Step-by-step explanation:
Margin of Error formula = z × s/√n
z = z score of confidence interval
We are given z score of 99% = 2.58
s = Standard deviation = $36
Margin of Error= ± 12
n= unknown
= 12 = 2.58 × 36/√n
12 × √n = 92.88
√n = 92.88/12
√n = 7.74
Square both sides
(√n)² = 7.74²
n = 59.9076
Approximately n ≈ 60
Therefore, the required sample size = 60
