Using the average rate of change, it is found that the average rate is of:
(1) 2.1 °F per minute
<h3>What is the average rate of change of a function?</h3>
It is given by the <u>change in the output divided by the change in the input</u>.
In this problem:
- At 15 minutes, the temperature was of 90ºF.
- At 45 minutes, the temperature was fo 153ºF.
Hence, in 30 minutes, the temperature increased 63ºF, hence the rate is given by:
r = 63/30 = 2.1 °F per minute.

Answer:
<h2>20%</h2>
Step-by-step explanation:
Step one:
total number of people surveyed= 1500
we are told that 300 people would buy that car again,
this implies that they like the car and are satisfied with it
Step two:
the percent of people satisfied can be computed as
=300/1500*100
=3/15*100
=1/5*100
=0.2*100
=20%
<u>The people surveyed were satisfied with the car are 20%</u>
Answer:
12 bats
Step-by-step explanation:
Let us number the bat caves from 1 to 45 and divide them into 5 parts:
a) 1
b) 2 to 29 (
bats)
c) 30
d) 31 to 44 (
bats)
e) 45
It is given that any 7 caves in a row has 77 bats. Hence, the total number of bats in part b and d = 
bats.
There remains 
bats in cave number 1, 30 and 45.
Now, our question demands the maximum possible number of bats in cave 30.
Minimum number of bats in a cave is 2. So we shall put 2 bats in the last cave, which gives us bats in the first cave.
Therefore, the number of bats in cave number 30 = 
bats.
