pickupchik [31]

Answer:

<u>y = 6 x=8</u>

Step-by-step explanation:

(3х + 5y = 54)-2 times by -2

-6х + -10y = -108 now combine the equations

6х + 4y = 72

-6y = -36 now divide

y = 6

Plug 6 in 6х +4 * 6 = 72

x=8

Given  sample size 'n'=76

Given the dean who randomly selects 76 students and finds that 58 out of 76 are receiving financial aid.

Sample proportion

                         p = \frac{x}{n} = \frac{58}{76} = 0.7631

The standard error is determined by

                     S.E = \sqrt{\frac{p(1-p)}{n} }

                     S.E = \sqrt{\frac{0.763(0.2369}{76} }

  Standard error is 0.048  ≅ 0.05
