Answer:

X° + 44° = 2x° + 11° [ Sum of two adjacent interior angles of a triangle = opposite exterior angle]

=> - x° = 11°-44°

=> -x° = -33°

=> x° = 33°

Therefore the value of x° = 33°

Hope it helps

An insurance company has written 52 policies of $50,000, 477 of $25,000, and 918 of $10,000

Ede4ka [16]

The amount of money that the company can expect to pay during the year the policies were written is; $25005

<h3>How to find the expected Value?</h3>

The probability that a person will die at age 20 = 0.001

Revenue from 52 policies = 52 * $75,000 = $3,900,000

Revenue from 477 policies = 477 * $25,000 = $11,925,000

Revenue from 918 policies = 918 * $10,000 = $9,180,000

Total revenue from all policies = $3,900,000 + $11,925,000 + $9,180,000

Total Revenue from all Policies = $25,005,000

Expected amount to pay out during the year the policies were written = $25,005,000* 0.001 = $25,005

Thus, the company can expect to pay out $45,000 over the year after the policies were written.

Write an equation of the form y = mx for the line shown below.

djyliett [7]

Answer:

y = -3x

Step-by-step explanation:

To get slope intercept, you divide both y values by both x values like this

$\frac{y_2 - y_1}{x_2 - x_1}$

In this case this will be $\frac{(-3 - 6)}{(1 - (-2))}$

This will become $\frac{-9}{3}$

Divide those two to get -3, and now you get your slope intercept.
