Answer:

x = -5/3 and y = -1

Step-by-step explanation:

write it as a system and simplify

-4 for the first equation (in the photo but when putting it into a system of equations it would be 2nd)

So it's

-3x-2y=7

-3x+2y=3

then it's -6x=10

then divide oth sides by -6 to get x then plug that into whatever equation and solve for y.

i hope this is right and helps

Answer:

The margin of error = 0.037

Step-by-step explanation:

Explanation:-

Given that the mean of the Population(μ) = 2.38

Given that the standard deviation of the Population(σ) = 0.59

Given sample size 'n' = 950

Level of significance = 0.05

The critical value( Z₀.₀₅) = 1 .96

The margin of error is determined by

$M.E = \frac{Z_{\alpha } S.D}{\sqrt{n} }$

$M.E = \frac{1.96 (0.59)}{\sqrt{950} }$

M.E = 0.037

Final answer:-

The margin of error = 0.037
