Answer:
49
Step-by-step explanation:
Given:
Width = 0.4
Let's take the z value of 95% which is = 1.96
Let's assume population proportion p1 and p2 = 0.5
For margin of error E, the relation between the width and margin of error is 2E.
i.e 2E = 0.4
E = 0.2
To find the sample size, n, let's use the formula :
![n= \frac{z^2*(p_1(1-p_1) + p_2(1-p_2))}{E^2}](https://tex.z-dn.net/?f=n%3D%20%5Cfrac%7Bz%5E2%2A%28p_1%281-p_1%29%20%2B%20p_2%281-p_2%29%29%7D%7BE%5E2%7D)
![= \frac{1.96^2(0.5(1-0.5)+0.5(1-0.5))}{0.2^2}](https://tex.z-dn.net/?f=%20%3D%20%5Cfrac%7B1.96%5E2%280.5%281-0.5%29%2B0.5%281-0.5%29%29%7D%7B0.2%5E2%7D)
= 48.02
≈ 49
Well I think that it’s A,B,D,E :)
5,200 x .07 = 364$ so then you’ll have 364 in commission
Its B I'm sure :), welcome..
Well, you can do it these two methods⬇

2 and 1/3 (which is also written as 2 1/3)

Theres only one way, but if you're putting it as a decimal then you just divide 7 from 3 to get your answer

•So, 7 ÷ 3 = 2.3
•And 2(3) + 1 = 7 / 3 (if that makes sense)
