There are 105 lettered tiles in a board game. you choose thetiles shown (r, a, i, l, m, b, e). how many of the 105 tileswould you expect to be vowels?

45

Step-by-step explanation:

Given: The total number of lettered tiles in a board game =105

The number of tiles chosen (R, A, I, L, M, B, E) = 7

the number of vowels chosen (A,I,E)=3

Now, the fraction or probability of choosing of vowels out of 7 given letters is given by :-

Now, the number of vowels we can expect to be vowels out of 105 letters is given by :-

Hence, the number of vowels we can expect to be vowels out of 105 letters is 45.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
