Answer:

(820 ; 980)

Step-by-step explanation:

Given :

Sample size, n = 80

Number of bilingual from sample = 36

Sample proportion, phat = x / n = 36 / 80 = 0.45

Margin of Error = 4% = 0.04

Interval = sample proportion ± margin of error

0.45 ± 0.04

(0.41 ; 0.49)

(0.41 * 2000 ; 0.49 * 2000)

(820 ; 980)

Steps to solve:

5x² = 15x

~Subtract 15x to both sides

5x² - 15x = 15x - 15x

~Simplify

5x² - 15x = 0

~Factor left side

5x(x - 3) = 0

~Factors equal 0

5x = 0 and x - 3 = 0

___________

~Simplify 5x = 0

5x/5 = 0/5

x = 0

~Simplify x - 3 = 0

x - 3 + 3 = 0 + 3

x = 3

___________

Thus, the correct answer is 0, 3.

___________

Best of Luck!
