Hi,

Solving:

\frac{2 {y}^{2} - 6y - 20}{4y + 12} \div \frac{ {y}^{2} + 5y + 6}{ 3 {y}^{2} + 18y + 27 } \\ \frac{2 {y}^{2} - 6y - 20}{4y + 12} \div \frac{3 {y}^{2} + 18y + 27 }{{y}^{2} + 5y + 6} \\ \frac{2( {y}^{2} - 3y - 10)}{4y + 12} \div \frac{3 {y}^{2} + 18y + 27}{ {y}^{2} + 5y + 6} \\ \frac{2( {y}^{2} - 3y - 10}{2(2y + 6)} \times \frac{3 {y}^{2} + 18y + 27}{ {y}^{2} + 5y + 6} \\ \frac{ \not2( {y}^{2} - 3y - 10) }{ \not2(2y + 6)} \times \frac{3( {y}^{2} + 6y + 9) }{ {y}^{2} + 5y + 6} \\ \frac{ {y}^{2} + 2y - 5y - 10 }{2(y + 3)} \times \frac{3( {y}^{2} + 6y + 9) }{ {y}^{2} + 3y + 2y + 6} \\ \frac{y \times (y + 2) - 5(y + 2)}{2(y + 3)} \times \frac{3(y + 3)^{2} }{y \times (y + 3) + 2(y + 3)} \\ \frac{ (y + 2) \times (y - 5)}{2(y + 3)} \times \frac{3(y + 3)^{2} }{(y + 3) \times (y + 2)} \\ \frac{y - 5}{2(y + 3)} \times 3(y + 3) \\ \frac{y - 5}{2} \times 3 = \frac{3y - 15}{2} \: \: \: \: \: \: \: \: \: \: \: \: result

Zielflug [23.3K]

For the probability of rain on julty 4h of 0.5 his expected profit is  8885.5 dollars.

<h3>What is probability?</h3>

The probability is occurrence of a certain event out of the total number f events that can happen.

Given in the question the probability of rain is 0.5 therefore the probability of not raining is also 0.5.

If it does not rain he makes a profit of 30427 dollars and if it rains he suffers a loss of 12656 dollars.

We know, the expected profit is,

= 0.5(30427) - 0.5(12656).

= 15213.5 - 6328.

= 8885.5 dollars.

To solve problem 1 what you need to do is figure out how many miles the girls have walked so far and then subtract that from the total distance they must complete.

3/4-(3/10+1/4)

Step 1:Change the denominators so that way they are all the same

3/4=15/20
3/10=6/20              15/20-(6/20+5/20)
1/4=5/20

Step 2: Begin solving the problem

6/20+5/20=11/20
15/20-11/20=4/20

Step 3: Simplify your answer

4/20=1/5

Step 4 (is optional): Write your answer in a complete statement

The three girls walk 1/5mile together to school

Answer: A

I hope this is correct and if not I apologize for giving false information.
