We know
In a function
x represents the input and y represents output
So
x is time
So
f(30) represents distance traveled in 30mins
Answer:
A. 0.75
B. Elsa can expect to gain 0.75 dollars
Step-by-step explanation:
We have six outcomes
Using the table in the attachment, the expected value was calculated.
Expected value = 0.166667+0.3333+0.5-0.083333-0.083333-0.083333
= 0.75
B. From the answer in part A , we can conclude that Elsa can expect to gain money. She can expect to win 0.75 dollars per roll.
A. Yes, the value of this function is 8 when x is 15.
B. False. I noted right away that the ordered pair (0,5) is not included, and some of the ordered pairs included do not represent the given function.
C. Yes, f(5) = 6. See (A) above.
D. False. The range of this function is the set of integers between 5 and 13 inclusive.
10. 5/8
Step one: turn 3/4 in to a common denominator as 1/8 which is 3/4 x2 which equals 6/8
Second step: 6/8 - 1/8 equals 5/8 and that should be your answer
Hope this helps
