Answer:

Hello, this would be a vertical angle graph. Since this graph is a supplementary graph since it stretches about 180 degrees, you would take both 7x and x+20 and set it equal to 180 like this:

7x+x+20=180

Then, you combine the xs and you would get this:

8x+20=180

Then, subtract 20 from both sides like this:

8x=160

Lastly, you would divide 8 by both sides and get x which is:

x=20

I hope this helped you!

Gracie’s insurance premiums are $150 per month. This year she also paid a $500 deductible and 20% of $3,000 for a minor accident

storchak [24]

Her insurance premiums are 150 per month.....there is 12 months in a year....so in 1 year, her premiums totaled : (150 * 12) = 1800

she paid a $ 500 deductible

she paid 20% of $ 3000 for the accident..
0.20 * 3000 = $ 600

therefore, her total healthcare expenses for 1 yr totaled :
1800 + 500 + 600 = $ 2900 <==

A sample of 4 different calculators is randomly selected from a group containing 14 that are defective and 34 that have no defec

marysya [2.9K]

Answer:

The answer is "0.7616".

Step-by-step explanation:

Using formula:

$\text{P( at least one de-fective) = 1 - P( all calculators work )}$

$= 1-(\frac{34}{48}\times \frac{33}{47}\times \frac{32}{46}\times \frac{31}{45})\\\\= 1-(\frac{34}{1}\times \frac{11}{47}\times \frac{1}{23}\times \frac{31}{45})\\\\=1-(\frac{11594}{48647})\\\\=\frac{48647-11594}{48647}\\\\=\frac{37051}{48647}\approx 0.7616$
