Answer:
1767 hours
Step-by-step explanation:
Given equation:
Where M is monthly number of sales and P is the number of employee hours.
Now, finding number of hours employee worksto have 300 monthly sales.
Using given equation to find the number of employee hours (P).
Subtituting the value of M, which is 300.
⇒
Subtracting both side by 48
⇒
⇒
Dividing both side by 6
⇒
⇒
Taking square of the number on both side.
remember, √a²= a
⇒
⇒
Adding 3 on both side
⇒
∴ P= 1767
Hence, 1767 hours must the employees work to have 300 monthly sales.
Answer:
The most appropriate way to state the conclusion is:
d. There is not enough evidence to say that men have a longer mean nose length than women.
Step-by-step explanation:
We have the result of a hypothesis test.
The claim was that men have a longer mean nose length than women.
That means that the alternative hypothesis states that men's mean nose length is higher than the women's mean nose length.
The P-value of the test is 0.225, which for any usual significance level is large enough to fail to reject the null hypothesis. Then, there is no enough evidence to support the claim that men have a longer mean nose length than women.
a. Men have a longer mean nose length than women.
FALSE. There is no enough evidence to support the claim.
b. The probability is 0.225 that men and women have the same mean nose length.
FALSE. That is not the meaning of the P-value.
c. The mean nose lengths of the populations of men and women are identical.
FALSE. We can not claim that the null hypothesis is true, even when we havo no enough evidence to reject it.
d. There is not enough evidence to say that men have a longer mean nose length than women.
TRUE. This is the the most appropriate way to state the conclusion.
Answer:
The area of the triangle is increasing at a rate 1.2 m²/s.
Step-by-step explanation:
Given sides of a triangle are 8 m and 10 m in length.
The angle between the sides of the triangle is increasing at a rate 0.06 rad/s.
It means
If the sides of a triangle are a and b and θ is the angle of the sides.
The area of the triangle is A =
Here, a = 8 m and b = 10 m
Differentiating with respect to t
putting the value of
=1.2 m²/s
The area of the triangle is increasing at a rate 1.2 m²/s.
