Answer:
57
Step-by-step explanation:
Given that :
Standard deviation (σ) = 5 minutes = (5 *60) = 300 seconds
Margin of Error, E = 78
Assume a confidence interval of 95%;
Using the relation :
((Zα/2 * σ) / E)²
(1 - α)/2 = (1 - 0.95)/2 = 0.05 /2 = 0.025
Z0.025 = 1.96
Sample size = ((1.96 * 300) / 78)²
Sample size = (588 / 78)^2
Sample size = 7.5384615^2
Sample size = 56.828
= 57 samples
Answer:
The new dimensions of the field will be 44.8 feet by 19.6
Step-by-step explanation:
since the scale factor is 1.4, all the original dimensions are multiplied by 1.4
32 times 1.4 is 44.8 and 14 times 1.4 is 19.6
There are four sets of numbers with 8 as their greatest common factor:
12 and 24
16 and 24
4 and 16 and
16 and 32
