30 POINTS FOR SIMPLE QUESTION

-4 = y + 3

y = -4x - 3

Solve for Y in the first equation:

-4 = y +3

Subtract 3 from both sides:

y = -7

Now using the addition method:

rewrite the second equation as 4x+y = -3

Multiply y = -7 by - 1 to get -y = 7

Now add the two together:

4x +y = -3

-y =7

4x = 4

Divide each side by 4:

x = 4/4 = 1

Then replace x in one of the equations to solve for y which is -7

X = 1, Y = -7

r-ruslan [8.4K]

Answer:

The Point estimate of the Population proportion E = 0.039≅0.04

Step-by-step explanation:

Step(i):-

Given that the sample size 'n' = 992

and x = 570

The Population proportion

$p = \frac{x}{n} = \frac{570}{992} = 0.5745$

Step(ii):-

The point estimate of the Population proportion is determined by

$E = 2.576 \frac{\sqrt{0.574(1-0.574)} }{\sqrt{992} }$

E = 0.039≅0.04

Final answer:-

The point estimate of the Population proportion E = 0.039≅0.04
