Mathematics

Answer:

75%

Step-by-step explanation:

List out known probabilities

\Pr(shirt) = 0.65 = \frac{65}{100} = \frac{13}{20}\\ \Pr(pants) = 0.40 = \frac{30}{100} = \frac{6}{20}\\\Pr(shirt \cap pants) = 0.20 = \frac{20}{100}=\frac{1}{5}

recall equation

\Pr(A \cup B)=\Pr(A)+\Pr(B)-\Pr(A \cap B)

Plug in values

\Pr(shirt \cup pants)=\frac{13}{20}+\frac{6}{20}-\frac{1}{5}\\\\therefore \Pr(shirt \cup pants) = \frac{15}{20} =\frac{3}{4} = 75\%

Answer:

1, 4/5,2/5

Step-by-step explanation:

y = 5x

Let y = 5

5 = 5x

Divide by 5

5/5 =5x/5

1=x

Let y=4

4 =5x

Divide by 5

4/5 =5x/5

4/5 =x

Let y=2

2 =5x

Divide by 5

2/5 =5x/5

2/5 =x

I will give you brainliest!!!! Use substitution method to solve the system of equations. y=6x-5 y=x+5
solong [7]

Answer:

(2,7)

Step-by-step explanation:

y=6x-5

y=x+5

Since they are both equal to y, set them equal to each other

6x-5 = x+5

Subtract x from each side

6x-x-5 = x+5-x

5x-5 = 5

Add 5 to each side

5x-5 +5 = 5+5

5x=10

Divide by 5

5x/5 = 10/5

x=2

y = x+5

y = 2+5

y =7

You gave your little sister a good push on a swing and it made an arc of 12 ft. On the third swing it made an arc of 8.67 ft. Ho
jonny [76]
10.2 ft Ans.

We solve this using geometric series.

A1 = 12 ft
A2 = ?
A3 = 8.67ft
Now, for geomteric progression,

\frac{A1}{A2} =  \frac{A2}{A3} &#10;&#10;


\frac{12}{A2} = \frac{A2}{8.67}

A2 * A2 = (A2)^{2}  =  \sqrt{12 * 8.67 } 
 
A2 = 10.2 ft
