Chanelle selects a marble from a container and then returns it to the container. When she does this 3 times, the probability of

astraxan [27]

Answer:

1 ÷ 6

Step-by-step explanation:

Let us assume the probability of the red marble for selecting it first time be x

And, it is to be done 3 times

that means

= 1 ÷ x × 1 ÷ x × 1 ÷ x

This equivalent to = 1 ÷ 216

And the 216 could be calculated by multiplied 6 3 times i.e.

= 6 × 6 × 6

= 216

So, the probability for selecting it for a first time is

= 1 ÷ 6

Find the slope of every line that is parallel to the line in the graph

RUDIKE [14]

When two lines are parallel they have the same slope
so the slope of the parallel line = the slope of the line in the graph= (Y2-Y1)/(X2-X1) = (5-(-7))/(1-(-2)) = 4
Do you understand?

REVIEW: Find the slope for the following situations. a. Given the equation y = 5x + 1 b. Given the equation 2x + y = 6 c. Given

DanielleElmas [232]

Answer:

Part 1) The slope is $m=5$

Part 2) The slope is $m=-2$

Part 3) The slope is $m=2$

Step-by-step explanation:

Part 1) we know that

The equation of the line into slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

$y=5x+1$

the slope is $m=5$

Part 2) we know that

The equation of the line in standard form is equal to

$Ax+By=C$

where

the slope is equal to $m=-\frac{A}{B}$

in this problem we have

$2x+y=6$

$A=2,B=1,C=6$

substitute

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

$m=-2$

Part 3) we know that

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

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

we have

$A(2,3)\ B(5,9)$

Substitute the values

$m=\frac{9-3}{5-2}$

$m=\frac{6}{3}$

$m=2$

Snowboarding was $118= pass + rental

rental was $25, therefore pass will be $118-$25= $93

To get the percentage
