Answer:
Option 1) is correct
Step-by-step explanation:
Given: The graph shows the distance in miles, m, hiked from a camp in h hours.
To find: hourly interval that had the greatest rate of change
Solution:
Rate of change between two points refers to the vertical change divided by the horizontal change.
For hour 0 to hour 1:
rate of change = 
For hour 2 to hour 3:
rate of change = 
For hour 1 to hour 2:
rate of change = 
For hour 3 to hour 4:
rate of change = 
So, rate of change is greatest in interval: hour 0 to hour 1
Step-by-step explanation:
100 = ( 8 + 2x) ( 10 + 2x )
100 = 80 + 36x + 4x ^2 ( binomial product )
80 + 36x + 4x^2 = 100
80 + 36x + 4×^2 - 100 = 100 - 100
4x^2 + 36x - 20 = 0

Using the binomial distribution, it is found that there is a 0.056 = 5.6% probability that more than 7 will make a purchase.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- There are 12 customers, hence n = 12.
- The probability of any of them making a purchase is of p = 0.4.
The probability that more than 7 will make a purchase is given by:
P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12).
Hence:
Then:
P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) = 0.042 + 0.012 + 0.02 + 0 + 0 = 0.056.
0.056 = 5.6% probability that more than 7 will make a purchase.
