What constant do you need to add to each quadratic to complete the square?
babunello [35]

Answer:

1. 4

2. 16

3. 9

Step-by-step explanation:

Completing the square requires a quadratic in ax^2+bx=c form. Once in this form, calculate (\frac{b}{2})^2.

1. (\frac{b}{2})^2=(\frac{-4}{2})^2=4

2. (\frac{b}{2})^2=(\frac{-8}{2})^2=16

3. Requires you divide everything by 3 first.

\frac{3x^2+18x}{3} =\frac{249}{3} \\x^2+6x=81

(\frac{b}{2})^2=(\frac{6}{2})^2=9

svp [43]

Answer:

0.2839 = 28.93%

Step-by-step explanation:

In order to find find the probability that one car chosen at random will have less than 68.5 tons of coal, we have to find z

Le x be tons of coal in a car

Z = (x – mean)/standard deviation

Z = (x – μ)/ σ

P (x<68.5) = P(z < (68.5-69)/0.9)

P (x<68.5) = P(z < -0.5555)

Then we use the z table to find the area under the curve.

P (x<68.5) = 0.2893
