Step-by-step explanation:
Answer:
d. 20
Step-by-step explanation:
Standard deviation is 4.5
Margin error for the problem is 2 hours
Probability 95%, that means that the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
2 = 1.96 * 4.5/ √n
2 = 8.82/√n
√n = 8.82/2
√n = 4.41
n = 4.41^2
n = 19.44 ≈ 20
Answer:
she would have 6 egg cartons to sell and 3 eggs left over (:
Step-by-step explanation:
75 divided by 12 equals 6.25
12 times 6 equals 72
75 minus 72 equals 3
egg cartons- 6
left over eggs-3
Hope this helps (:
25 goes into 200 exactly 8 times.
