Answer: 16
Step-by-step explanation:
Standard deviation is 2
Margin error for the problem is 1
Probability 95%, that means thet 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
1 = 1.96 * 2/ √n
1 = 3.92 / √n
√n = 3.92
n = 3.92^2
n = 15.36 = 16
i hope this work for you

Answer: 9
explanation:
4+(-7)= -3
next, you multiply -3 and -3 which is 9 as the two negatives cancel out
One bag of soil is 5/8 pounds.
you have 16 of them.
just multiply 16 by 5/8.
you could just type it into your calculator, or you could do it the long way:
![16 * \frac{5}{8} \\ \frac{16*5}{8} \\ \frac{8*2*5}{8} \\ 2*5\\10](https://tex.z-dn.net/?f=16%20%2A%20%20%5Cfrac%7B5%7D%7B8%7D%20%5C%5C%20%5Cfrac%7B16%2A5%7D%7B8%7D%20%5C%5C%20%20%5Cfrac%7B8%2A2%2A5%7D%7B8%7D%20%5C%5C%202%2A5%5C%5C10)
