For this case we have the following inequality:

From here, we define the variable x.
x: number of minutes remaining to finish the race.
From here, we clear the value of x.
We have then:

Therefore, Samuel has less than 22.5 minutes to finish the race in the estimated time.
Answer:
x < 22.5; Sam has fewer than 22.5 minutes left to finish running.
Answer:
Step-by-step explanation:
1/10 * 1/4 = 1/14
1/2 because there is a 50/50% chance its either heads or tails
The answer is number two since in y=Mx+c, C is the y intercept. This means that 52 is the y intercept. Therefore, Jordan is charged $52 for each gigabyte of data she uses.
Answer:
b. 9.2 minutes
Step-by-step explanation:
To find the expected waiting time for a random call from the sampie given by using the formula:

number of calls (x) waiting time f(x) in minutes f(x) *(x)
0 0 0
2 3 6
4 10 40
6 15 90
8 10 80
10 6 60

Therefore:


F(x) = 2x²+3x
g(x)= x-2
f(x)+ g(x) =( 2x²+3x ) +(x-2)
= 2x²+3x+x-2
= 2x²+4x-2
(f+g)(2) = 2(2)²+4(2)-2
= 2•4+8-2
= 8+8-2
= 14
hope to helped
