Answer:

\frac{10}{7}  \: or \: 1 \frac{3}{7}

Step-by-step explanation:

-  \frac{5}{7}  \div  -  \frac{1}{2}  =  -  \frac{5}{7}  \times  -  \frac{2}{1}

First you reciprocate the fractions and change the division sign to multiplication.

- 5 \times  - 2 = 10 \: and \: 7 \times 1 = 7

Therefore the answer is:

\frac{10}{7}

A construction company plans to invest in a building project. There is a 30% chance that the company will lose $30,000, a 40% ch
Gnom [1K]

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

30% chance that the company will lose $30000.

40% chance of a break even that there is no loss and no profit.

30% chance that the company will profit $ 60000.

As we know the formula for "Expectation":

So, Expected value will be

\frac{30}{100}\times (-30000)+\frac{40}{100}\times 0+\frac{30}{100}\times 60000\\\\=03\times (-30000)+0.4\times 0+0.3\times 60000\\\\=-9000+18000\\\\=\$9000

Expected value is $9000. So, the company should proceed with the project.

Hence, Option 'A' is correct.

Citrus2011 [14]
<h2>y + 1 = -3(x - 10)</h2>

Here's the formula:

y - y1 = m(x - x1)

Substitute numbers accordingly:

y1: so 1 goes in the y1 spot (you switch the signs because it was already negative)

x1:  and 10 goes to the x1 spot

m:  -3 belongs in m
