Answer:
Let say 75% of cars older than age = Y years
than 25 % cars of age less than Y Years
Z score corresponding to 25 % = -0.674
Z score = (Value - Mean) /SD
Value = Y
Mean = 8
SD = 3.2
Z score = -0.674
-0.674 = (Y - 8)/3.2
=> Y =5.84 Years
=> Y ≈ 5.9 Years
Approximately 75% of cars driven by company employees are older than about 5.9 years

Answer:
The value of y = 11/2
Step-by-step explanation:
As the work is completed up to the point
![\frac{11}{5}=\frac{2}{5}y](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B5%7D%3D%5Cfrac%7B2%7D%7B5%7Dy)
Now completing the remaining work
![\frac{11}{5}=\frac{2}{5}y](https://tex.z-dn.net/?f=%5Cfrac%7B11%7D%7B5%7D%3D%5Cfrac%7B2%7D%7B5%7Dy)
Dividing both sides by 2/5

Therefore, the value of y = 11/2
Answer:
YES
Step-by-step explanation:
2(2) + 3(1) = 4+3= 7 then, 8(2) - 3(1) = 16 - 3 = 13
x=2
y=1
