Answer:
30=2*3*5, so it's 30
Step-by-step explanation:
15=3*5, so it's not 15
20=2*2*5, so it's not 20
30=2*3*5, so it's 30
57=19*3, so it's not 57
Answer:
Check Explanation.
Step-by-step explanation:
The sample will be a representative of the entire build us in the city.
For a sample size 35, 3 have fire code violations, hence, the proportion of houses with fire code violations = (3/35) = 0.0857 = 8.57 %
The uncertainty in the estimate is given in the form of standard error.
Standard error = √[(p(1-p)/n]
n = sample size = 35, p = 0.0857, 1 - p = 0.9143
Standard error of the sample = √(0.0857×0.9143/35) = 0.1616
In terms of the population, (0.1616/35) = 0.00462
Proportion of buildings with fire code violations = (8.57 ± 0.462) %
Answer: 3 1/3
Step-by-step explanation:
Turned into mixed numbers: -7/3 + 17/3
Multiply all the numbers by 3: -7 * 3 = -21
17 * 3 = 51
3 * 3 = 9
-21 + 51 = 30
30/9
30/9 = 3 1/3
