A.What is the slope of the graph?<br><br> B.Write an equation for the line.

jolli1 [7]

Answer:

Part A) The slope is $m=-\frac{1}{2}$

Part B) The equation of the line is $y=-\frac{1}{2}x-1$

Step-by-step explanation:

Part A) What is the slope of the graph?

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

Looking at the graph it takes any two points

(-2,0) and (0,-1)

substitute the values in the formula

$m=\frac{-1-0}{0+2}$

$m=\frac{-1}{2}$

$m=-\frac{1}{2}$

Part B) Write an equation for the line

we know that

The equation of the line in slope intercept form is

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

we have

$m=-\frac{1}{2}$

$b=-1$ ----> the y-intercept is the point (0,-1)

substitute

$y=-\frac{1}{2}x-1$

A batch consists of 12 defective coils and 88 good ones. Find the probability of getting two good coils when two coils are rando

Nastasia [14]

Answer:

The probability of getting two good coils is 77.33%.

Step-by-step explanation:

Since a batch consists of 12 defective coils and 88 good ones, to determine the probability of getting two good coils when two coils are randomly selected (without replacement), the following calculation must be performed:

88/100 x 87/99 = X

0.88 x 0.878787 = X

0.77333 = X

Therefore, the probability of getting two good coils is 77.33%.
