The answer would be -43/60 or -0.716 in decimal.
Answer:
slope = -2
y-intercept = 7
Step-by-step explanation:
<u>Slope formula:</u> y=mx+b
In every equation that follows this formula, <em>m </em>is slope and <em>b</em> is y-intercept.
Mayumi: 3 miles / 2 hours.
12 miles / 3 miles = 4
12 miles / 8 hours
Edwin: 4 miles / 3 hours.
12 miles / 4 miles = 3
12 miles / 9 hours.
Edwin takes more time to complete a 12-mile hiking trail. He takes 1 hour more than Mayumi.
The correct answer is option D which is the difference between the mean times is about 16 times the mean absolute deviation of the data sets.
<h3>What is mean?</h3>
Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.
The difference between the mean times is about 16 times the mean absolute deviation of the data set.
127.9-127.4=0.5
0.26-0.23=0.03
0.5/0.03=16.6666
We can see that the ratio of the mean times difference is 16 times the mean deviation by solving the above.
Therefore the correct answer is option D which is the difference between the mean times is about 16 times the mean absolute deviation of the data sets.
