Answer:
the probability is 0.0202
Step-by-step explanation:
The computation is shown below:
Given that
The Average life span = 17 hours
Standard deviation = 0.8 hours
Sample = 30 batteries
Sample mean = 16.7 hours
Now based on the above information
The probability is

Hence, the probability is 0.0202
The answer is (f . g)(x) = - (34k + 17k⁷ + 17k⁵ + 40k³ + 20k² + 60).
Remember that :
<u>(f . g)(x) = f(x) × g(x)</u>
<u />
Hence :
- (f . g)(x) = (2k³ + k² + 3)(-17k⁵ - 20)
- (f . g)(x) = -34k⁸ - 17k⁷ - 17k⁵ - 40k³ - 20k² - 60
- (f . g)(x) = - (34k + 17k⁷ + 17k⁵ + 40k³ + 20k² + 60)
Answer:
The value of h is 42.956 approximately.
Step-by-step explanation:
Consider the provided formula 
Here d is the distance of the driver from the letters and e is the height of the driver's eye above the pavement. All of the distances are in meters.
We need to find the value of h where the value of d = 92.4 m, e = 1.7 m.
Substitute d = 92.4 m, e = 1.7 m in above formula and solve for h.




Hence, the value of h is 42.956 approximately.
48.6153846 is the answer
