Answer:

x=6

Step-by-step explanation:

-2(x + 4)= -20

<u>Divide both sides by -2:</u>

<u />x+4=\cfrac{-20}{-2}<u />

<u>Divide -20 by -2 = 10</u>

<u />x+4=10<u />

<u>Subtract 4 from both sides:</u>

<u />x=10-4<u />

<u />x=6<u />

Use the functions f (x)= –x^2 + 8x – 11, g(x) = 14 - 2/3x,and h(x) = -x – 7 to find each function value.
Ksju [112]

Answer:

15

Step-by-step explanation:

input each of the values (g=9 and h= -14) and solve then add them together

g(9) = 14 - 2/3 (9)

14 - 18/3 (or 6) = 8

h(-14) = -(-14) - 7

14 - 7 = 7

8 + 7 = 15

The average number of accidents is 3 per month, what is the probability of 1 accident?
tatuchka [14]
<h2>Hello!</h2>

The answer is: 33.33%

<h2>Why?</h2>

Since we have the average number of accidents that occurs in 1 month, and it's equal to 3, we can calculate the probability of 1 accident occurs by dividing it into the average number of accidents, using the following formula:

Probability=\frac{FavorableOutcomes}{Outcomes}*100

Where,

Favorable outcomes are the occurrence of the event, for this case, it's equal to 1.

Outcomes are the possible occurrence of the event, for this case, it's equal to 3.

So, by substituting we have:

Probability=\frac{1}{3}*100

Probability=0.3333*100=33.33

So, the probability will be equal to 33.33%

Have a nice day!
