Answer:
Step-by-step explanation:
Given coordinates are (6,-3) and (-5,-4).
![\sf Slope = \frac{y2-y1}{x2-x1}\\\\Slope = \frac{-4+3}{-5-6} \\\\Slope = \frac{-1}{-11} \\\\Slope = \frac{1}{11} \\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Csf%20Slope%20%3D%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B-4%2B3%7D%7B-5-6%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B-1%7D%7B-11%7D%20%5C%5C%5C%5CSlope%20%3D%20%5Cfrac%7B1%7D%7B11%7D%20%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)

PEMDAS
doing the stuff in the parenthesis first
71.1 - 2.27 x (2)4
then multiply left to right
71.1 - 4.54*4
71.1 - 18.16
52.94
therefore 52.94 should be your answer
Answer: 400
Step-by-step explanation:
From the question, we see that population proportion (p) = 0.15
Margin of error (m) = 5%
Confidence level = 99%
Level of significance = 100- confidence level = 1%.
The population standard deviation (s) for this data set is
√p(1-p) = √ 0.15 × (1 - 0.15)
√ 0.15 × 0.85 = 0. 1275
Margin of error = critical value × population standard deviation / √n
The critical value (c) for Constructing a 99 % confidence interval for population mean is = 2.58
m = c× √p'(1-p') /√n
We want to make n subject of the formulae, we have that
m = c√p'(1-p') /√n
m×√n = c × √p'(1-p')
√n = c × √p'(1-p') / m
n = c² × {√p'(1-p')}² / m
n = 2.58² × 0.1275/ 0.05²
n = 6.6564 × 0.01625625 / 0.0025
n = 339.47 ~ 400
