Answer:

See attached image

Step-by-step explanation:

If you have two marbles in a bag and you are choosing the marbles randomly twice, then we can look at fractions.

Each time, you have a 0.5 chance of picking the silver marble. After you pick that, you have another 0.5 chance of picking the silver marble again.

This applies with any combination.

This means that the probability of you getting two silvers in a row is 0.25.

Since the marbles are the same size and nothing is stopping you from choosing one, this probability applies to all combinations possible.

Hope this helped!

evablogger [386]

i would say you need to divide 45 and 3. then subtract 45 and 15. then with those two numbers you need to put the amount from 45 / 3 on the top and the 15-45 on the bottom. you will get the probability.

A basketball player made 17 out of 20 freee throws at practice what percent of the free throws did the player misss

Igoryamba

Answer: 15%

Step-by-step explanation: To find what percent of free throws the player misses we will have to write a percent equation.

For this situation the equation 17/20 = x/100 will work.

This means that if the player made 17 free throws out of 20, what percent did he make.

Solve for x.

17/20 = x/100

17/20 x 100 = x/100 x 100

1700/20 = x

85 = x

The basketball player made 85% of his free throws.

You want to find the percent of free throws he misses.

So you can simply subtract 100% from 85% to get 15%

The basketball player misses 15% of his free throws.

5 Select the correct expressions. Which expressions are equivalent to 3x + 2(x - 1) - 4? 3x + 2x - 2 - 4 5x - 6 3(x-4) 3(x + 2)

beks73 [17]

Your question is a bit unclear, but I will try to answer it anyway.

The expression 3x + 2(x - 1) - 4 simplified is:

3x + 2(x - 1) - 4

= 3x + 2x - 2 - 4

= 5x - 6

I cannot tell what the answers are but I am guessing they are these?:

A) 3x + 2x - 2 - 4

B) 5x - 6

C) 3(x - 4)

D) 3(x + 2) - 6

E) 6(x - 1)

Answer A is one, and so is answer B. If I read your question accurately.

I hope I helped!
