Answer:

x = -2      <u><em>OR</em></u>     x = -3

Step-by-step explanation:

=> x^2+5x+6 = 0

Using mid-term break formula

=> x^2+2x+3x+6 = 0

=> x(x+2)+3(x+2) = 0

Taking x+2 common

=> (x+2)(x+3) = 0

So Either,

x+2 = 0   <u><em>OR</em></u>    x+3 = 0

x = -2      <u><em>OR</em></u>     x = -3

Artist 52 [7]
Answer: The percent higher is 41.68%. If 49 planes were selected, 20 of them should be above 15 years.

To find the percent, we first need the z-score.

(15 - 13.5) / 7.3 = 0.21

Now, use a normal distribution table to find the percent above a score of 0.21. It will be 41.68%.

To find the number of 49 planes above this value, multiply 49 by 0.4168. You will have about 20.4 planes.
