If you randomly select a letter from the phrase "Mario kart on the Wii's fun", what is the probability that it was like a vowel? (Your answer must be in the form of a reduced fraction.)

The probability that it is a vowel is 3/7

Step-by-step explanation:

For this we have to count the number of letters the phrase contains

"Mario kart on the Wii's fun" = 21

the phrase has a length of 21 letters

now we count how many vowels the phrase has

"Mario kart on the Wii's fun"

"aio a o e ii u" = 9

the phrase has 9 vowels

To know the probability we have to do the number of vowels over the number of letters

9/21

as it asks us that the fraction is reduced we have to simplify by 3

9 = 3*3     21 = 3*7

9/21 = 3*3 / 3*7

9/21 = 3/7

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
