Answer: d) $369.31 to $380.69
Step-by-step explanation:
Given;
Mean price x= $375
Standard deviation r= $20
Number of retail stores n = 50
Confidence interval of 95%
Z*(95%) = 1.96
Confidence interval = x+/-Z*(r/√n)
= $375+/- 1.96(20/√50)
= $375+/- 5.69
Confidence interval = ($369.31 to $380.79)
The difference (I'm assuming you meant difference) between 279 and 63 is
279 - 63 = 216
so divide 432 by 216
432 / 216 = 2
so the answer is 2

Answer:
x = 33.6
Step-by-step explanation:
Formula to be used for the scale factor,
Scale factor = 
From the figure attached,
Side length of the big triangle = x
Corresponding side length of small triangle = 28
Scale factor = 
x = 
x = 33.6
