What is the equation of the line parallel to the given line.

dedylja [7]

The equation of the line is y=1/5x-3 so the parallel line is going to have the same slope but a different b.

Plug in (-2,2) in the equation
2=1/5(-2)+b
2=-2/5
12/5=b

Equation: y=1/5x+12/5

A student prepares for an exam by studying a list of 10 problems. She can solve 8 of them. For the exam, the instructor selects

lianna [129]

Answer:

Probability to solve 7 problem will be equal to $\frac{1}{15}$

Step-by-step explanation:

It is given total number of question = 10

She can solve 8 of them from 10 questions

We have to find the probability that she can solve 7 question

Probability will be equal to ratio of favorable outcome to total sample space

Favorable outcome will be equal to $^8c_7$

Total sample space $=^{10}c_7$

So probability will be equal to $P=\frac{^8C_7}{^{10}C_7}=\frac{6}{90}=\frac{1}{15}$

So probability to solve 7 problem will be equal to $\frac{1}{15}$
