Answer:

It is -6.

Step-by-step explanation:

7 + 12 is 19

b + (7 + 12) = 13

b + (19) = 13

-6 + 19 = 13

The answer you are looking for is b = -6.

There are 2 ways to find this. You could use...

Add together 7 and 12 to get 19, then subtract 19 from both sides to get b = -6. OR...
Subtract 12 from both sides to get b + 7 = 1, then subtract 7 from both sides to get b = -6.

Either way, you will get the same answer of b = -6. One method is just longer than the other. I hope this helps!

4. What is the measure of angle ABD in the figure below?*<br> D<br> 2x<br> A<br> B<br> с

Answer:

Measure of exterior angle ABD = 136°

Step-by-step explanation:

Given:

measure of ∠A = (2x + 2)°

measure of ∠C = (x + 4)°

measure of ∠B = x°

Find:

Measure of exterior angle ABD

Computation:

Using angles sum property

∠A + ∠B + ∠C = 180°

So,

(2x + 2) + (x + 4) + x = 180

4x + 6 = 180

4x = 176

x = 44

So,

measure of ∠B = x°

measure of ∠B = 44°

Measure of exterior angle ABD = 180 - measure of ∠B

Measure of exterior angle ABD = 180 - 44

Measure of exterior angle ABD = 136°

An airline is planning its staffing needs for the next year. If a new route is approved, it will hire 837 new employees. If a n

dusya [7]

Considering a discrete distribution, it is found that the expected number of new employees to be hired by the airline is of 446.16.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

In this problem, considering the situation described in the text, the distribution is given by:

P(X = 837) = 0.37.

P(X = 199) = 0.63.

Hence, the expected value is given by:

E(X) = 0.37(867) + 0.63(199) = 446.16.
