Given equation is 2x²+x-28 = 0

⇛ 2x²+8x-7x-28 = 0

⇛ 2x(x+4)-7(x+4) = 0

⇛ (x+4)(2x-7) = 0

⇛ x+4 = 0 or 2x-7 = 0

⇛ x = -4 or 2x = 7

⇛x = -4 or x = 7/2.

Travka [436]

Answer:

solution is given below

Step-by-step explanation:

A simple random sample size n = 250 . Of the 250 employed individuals ​surveyed,42 responded that they did work at home at least once per week.

Construct 99% confidence interval for population

For proportion : 42 / 250 = 1/10 = 0.16

Mean = 2.5 * sqrt [ 0.1 * 0.9  / 250]

     = 2.5 * 0.01

    = 0.47

0.10 - 0.047 < p < 0.10 + 0.047
