Answer:
The standard deviation of car age is 2.17 years.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 7.5
(a) If 99.7% of the ages are between 1 year and 14 years, what is the standard deviation of car age?
This means that 1 is 3 standard deviations below the mean and 14 is 3 standard deviations above the mean.
So
I want to find
The standard deviation of car age is 2.17 years.
Answer:
Yes he have enough white paint.
Step-by-step explanation:
We are given
6 gallons of light green paint use → gallons of white paint
using the unitary method
1 gallons of white paint → 6*8/3 gallons of light green paint
→ 16 gallons of light green paint
but Liam have 9/16 gallons of white paint
9/16 gallons of white paint → 16* 9/16 gallons of light green paint
→ 9 gallons of light green paint
Yes Liam have enough white paint to make 8 gallons of light green paint.
