Ernesto wants to buy a snack from the vending the machine. The vending machine has 5 different kinds of chips, 8 different candy bars, and 2 different kinds of cookies. If he chooses one at random, what is the probability that it is a cookie? 215

213

13

152

about 13%

Step-by-step explanation:

there is a total of 15 snacks. 2 out of the 15 are cookies. Divide 2/15 and you get 0.13 repeating. That as a percent is 13

Hope it’s correct!

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
