<u><em>The complete question is</em></u>
The table shows how far a distance runner has traveled since the race began. What is her average speed, in miles per hour, during the interval 0.75 to 1.00 hours?
Time Elapsed (Hours) Miles Traveled (Miles)
0.50 2.00
0.75 3.50
1.00 4.75
Let
x ----> the time in hours
f(x) ----> the distance traveled in miles
so
we have
x (Hours) 0.50 0.75 1.00
f(x) (Miles) 2.00 3.50 4.75
we know that
To find the average speed, we divide the change in the output value by the change in the input value
the average speed is equal to
In this problem we have
Substitute

Answer:
52.56% probability that eight or more of the flights will arrive on time.
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it is on time, or it is not. The probability of a flight being on time is independent from other flights. So we use the binomial probability distribution to solve this question.]
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
At a certain airport, 75% of the flights arrive on time.
This means that 
A sample of 10 flights is studied.
This means that 
Find the probability that eight or more of the flights will arrive on time.
In which
52.56% probability that eight or more of the flights will arrive on time.

The question is Let h(x)=2x+5 and <span>g(x)=8-3x
what is the value of </span><span>h(g(1.5))
the answer
</span>h(g(1.5))= 2g(1.5)+5, and <span>g(1.5)=8-3(1.5)=3.5, so
</span>h(g(1.5))= 2<span>(3.5)+5= 12
</span>h(g(1.5))= 12
