Answer:
Step-by-step explanation:
The function is incorrect as its roots are imaginary .
So, the correct function is
Differentiating with respect to we get
Equating with zero
Double derivative of the function
So, the function is maximum at
Maximum profit is
The maximum profit made by the company is
The number of clients required to make the maximum profit is .
3/12 because if you reduse 3/12 then you will get 1/4 and that is greater than 1/7
Answer:
48 , 132
Step-by-step explanation:
Let smaller angle = x
Larger angle = 3x - 12
x & (3x - 12) are supplementary
So, x + 3x - 12 = 180°
4x - 12 = 180
4x = 180 +12
4x = 192
x = 192/4
x = 48°
Larger angle = 3*48 - 12 = 144 - 12 = 132
Answer:
21.6 hours
Step-by-step explanation:
Hypothesis testing allows to identify a event test. The correct order of the steps of a hypothesis test is given following
1. Determine the null and alternative hypothesis.
2. Select a sample and compute the z - score for the sample mean.
3. Determine the probability at which you will conclude that the sample outcome is very unlikely.
4. Make a decision about the unknown population.
These steps are performed in the given sequence to test a hypothesis.
The principal tests the hypothesis with a mean of 21.6 hours for the determination of average amount of time spent watching television.
