Answer:

18 students

Step-by-step explanation:

45 - 15 = 30 students only read physics

52 - 15 = 37 students only read chemistry

15 students read both

add all of them:

30 + 37 + 15 = 82

subtract the sum from 100

100 - 82 = 18

18 students doesn't study neither

Anestetic [448]

Answer:

From least likely to most likely:

Colorado Bronze wins

I Am Pat wins

Good Legs Lance wins

Step-by-step explanation:

Converting all probabilities to the same type may be easier to visualize and see the chances. Let's convert each chance to percentage:

P(I Am Pat wins) = 3/10 = <u>30%</u>

P(Good Legs Lance wins) = 0.6 = <u>60%</u>

P(Colorado Bronze wins) = 10%= <u>10%</u>

Thus, the desired order is:

Colorado Bronze wins

I Am Pat wins

Good Legs Lance wins

Answer:

The solution to the system of equations be:

x=3,\:y=-1

Hece, option B is correct.

Step-by-step explanation:

Given the system of equations

\begin{bmatrix}x-3y=6\\ 2x+2y=4\end{bmatrix}

Multiply x − 3y = 6 by 2:      2x-6y=12

\begin{bmatrix}2x-6y=12\\ 2x+2y=4\end{bmatrix}

so

2x+2y=4

-

\underline{2x-6y=12}

8y=-8

so the system of equations becomes

\begin{bmatrix}2x-6y=12\\ 8y=-8\end{bmatrix}

Solve 8y = -8 for y

8y=-8

Divide both sides by 8

\frac{8y}{8}=\frac{-8}{8}

y=-1

\mathrm{For\:}2x-6y=12\mathrm{\:plug\:in\:}y=-1

2x-6\left(-1\right)=12

2x+6=12

subtract 6 from both sides

2x+6-6=12-6

2x=6

Divide both sides by 2

\frac{2x}{2}=\frac{6}{2}

x=3

Therefore, the solution to the system of equations be:

x=3,\:y=-1

Hence, option B is correct.
