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:
The approximate percentage of cars that remain in service between 59 and 69 months is 2.35%.

Answer:
y=-3x+10
Step-by-step explanation:
slope = y2-x2/y1-x1
4-(-5)/2-5
9/-3
-3
y=-3x+b
Plug in 2,4:
4=-3(2)+b
4=-6+b
10=b
y=-3x+10
Hope this helps plz hit the crown :D
