Answer:

<h2>$42000</h2>

Step-by-step explanation:

step one:

Given that the initial salary is  $40,000

each year and the expected pay rise is $2000 each year

step two:

We can calculate her expected earnings at the end of the year to be

= salary +expected pay rise

=$40000+$2000

= $42000

<h2>Hence at the end of the year, she will earn a total of  $42000</h2>

I ONLY NEED HELP WITH PART B
kozerog [31]

Hi there

5x+3(x-5)=6x+2x-15

Simplify both sides of the equation

5x+3(x-5)=6x+2x-15

Distribute

5x+3x-15=6x+2x-15

Combine like terms

(5x+3x)-15= (6x+2x)-15

8x-15=8x-15

Subtract 8x from both sides

8x-15-8x=8x-15-8x

-15=-15

Add 15 to both sides

-15+15=-15+15

0=0

All real numbers are solutions

To solve this equation I used " The distributive property"


I hope that's help !

Good night !

A triangle has a square on its three sides as shown below. What is the value of x
anygoal [31]

using the pythagorean theorem

a^2+b^2 = c^2   where c is the hypotenuse

9^2 +12^2 = x^2

81 + 144 = x^2

225 = x^2

taking the square root of each side

sqrt(225) = x

15 =x

x = 15 inches

skelet666 [1.2K]

Answer:

The probability of exactly 2 breakdowns next month = 0.08422

Step-by-step explanation:

To calculate the probability of exactly 2 breakdowns next month, we use Poisson distribution formula.

P(X = x) = (e^-λ)(λˣ)/x!

Mean = λ = 5 breakdowns per month

x = 2 breakdowns per month

P(X = 2) = (e⁻⁵)(5²)/2!

P(X = 2) = 0.08422
