Answer:
Step-by-step explanation:
In a World Atlas study, 10% of people have blue eye color. Lane decided to observe 29 people and she concluded 5 people had blue eyes. Calculate the z-score
Given that :
Sample size (n) = 29
Number of people with blue eyes (x) = 5
Proportion (p) = 10% = 0.1
Using the relation :
Z = (p" - p) / sqrt(pq/n)
Recall : q = 1 - p = 1 - 0.1 = 0.9
p" = x / n = 5 / 29 = 0.1724137
pq = 0.1 * 0.9 = 0.09
Hence,
Z = (0.1724137 - 0.1) / sqrt(0.09/29)
Z = 0.0724137 / 0.0557086
Z = 1.2998657
It’s B the slope is 1/3 that’s why
6, 16, 26, 36, 46, 56, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 76, 86, 96 so 20 6's
The answer is 95ft
1. Set up an equation 52-x=-43
2. Subtract 52 from both sides -x=43-52
3. Simplify -x=-95
4. x=95
All the best (if you don't understand the equation let me know if you want help)
