A fitness center runs a contest for customers who enroll in its annual membership plan. The customers are allowed to draw a coup

Alchen [17]

There are 35 coupons in the jar.
The probability to choose coupon for 1 month of extended membership is $p(A)= \frac{20}{35} = \frac{4}{7}$ .
The probability to choose coupon for 1.5 months of extended membership is $p(B)= \frac{10}{35} = \frac{2}{7}$ .

Answer: With probability $\frac{4}{7}$ a customer will get 30 days extended membership, 
with probability $\frac{2}{7}$ a customer will get 450 days extended membership,
with probability $\frac{1}{7}$ a customer will get 60 days extended membership.
The probability to choose coupon for 1 month of extended membership is $p(C)= \frac{5}{35} = \frac{1}{7}$ .
Together P(A)+P(B)+p(C)=1.

A square piece of plywood has sides that are 10 feet long. What is the piece of plywood's area

Anuta_ua [19.1K]

I don’t really understand the question, but if you’re looking for the area, it would be 100 feet since you have to do “Side x Side”. Hope this helps!

The sum of 2 numbers is 30 and the difference is 10. What are the two numbers.

maw [93]

Answer:

20 + 10 = 30

Step-by-step explanation:

The sum of x and y is 30. In other words, x plus y equals 30 and can be written as equation A:

x + y = 30

The difference between x and y is 10. In other words, x minus y equals 10 and can be written as equation B:

x - y = 10

Now solve equation B for x to get the revised equation B:

x - y = 10

x = 10 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 30

10 + y + y = 30

10 + 2y = 30

2y = 20

y = 10

Now we know y is 10. Which means that we can substitute y for 10 in equation A and solve for x:

x + y = 30

x + 10 = 30

X = 20

Summary: The sum of two numbers is 30 and their difference is 10. What are the two numbers? Answer: 20 and 10 as proven here:

Sum: 20 + 10 = 30

Difference: 20 - 10 = 10
