Find the slope of the line through each pair of points.

1 answer:

8 0

You can use this formula: (y1 - y2) / (x1-x2)

For example, using question 5,

(-11-16)/ [-6-(-20)]
= -17/14

Given that it is a negative number, it would mean that the line is downward-sloping.

All the best!

Answer:

2.35%

Step-by-step explanation:

Mean number of months (M) = 39 months

Standard deviation (S) = 10 months

According to the 68-95-99.7 rule, 95% of the data is comprised within two standard deviations of the mean (39-20 to 39+20 months), while 99.7% of the data is comprised within two standard deviations of the mean (39-30 to 39+30 months).

Therefore, the percentage of cars still in service from 59 to 69 months is:

$P_{59\ to\ 69}=\frac{P_{9\ to\ 69}-P_{19\ to\ 59}}{2} \\P_{59\ to\ 69}=\frac{99.7-95}{2}\\P_{59\ to\ 69}=2.35\%$
