When you say "I want to make sure that I solved them correctly,
the tasteful, less suspicious thing to do is to list YOUR solutions,
so that the responder can either say "that one's correct" or else
show you how to do it.

1). HHH
HHT
HTH
HTT
THH
THT
TTH
TTT
a).  The probability of each one is 1/8 = 12.5% .
b). There's only one of those on the list.  12.5%
c). 12.5%
d). There are 3 ways that can happen.  3/8 = 0.375 = 37.5%

2). There are 16 possible outcomes.
a). Prob of each outcome is  1/16 = 0.0625  =  6.25% .
b). There's only 1 way that can happen, so it's 6.25% .
c). There's only 1 way that can happen, so it's 6.25% .

What is the solution to the equation 3x+2=x+8
sertanlavr [38]

Answer:

x=3

Step-by-step explanation:

3x+2=x+8

Subtract x from both sides.

3x+2−x=x+8−x

2x+2=8

Subtract 2 from both sides.

2x+2−2=8−2

2x=6

Divide both sides by 2.

2x/2=6/2

x=3

a student wrote this:"A triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism
Y_Kistochka [10]

Answer:  "A triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 cubic inches."

Step-by-step explanation:

<em>"A triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 square inches."</em>

"A triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 square inches."

There is the error, we measure volume in cubic inches.

The writing should read- "A triangular prism has a height of 15 inches and a base area of 20 square inches. The volume of the prism is 300 cubic inches."

It's the (IV) question with the spinning sector really need this answer anything will be appreciated it's got to do with probabi
galben [10]
Add up the frequencies to find the total frequency and that is your denominator.
5+10+12+10+13=50
Then their frequencies are the numerators.
5/50
10/50
12/50
10/50
13/50
Then times the fractions by two to make the denominator 100 so that you can easily turn these fractions into percentages.
10/100 = 10%
20/100 = 20%
24/100 = 24%
20/100 = 20%
26/100 = 26%
Then just double check that they add up to 100%
