2 answers:

8 0

(fog)(x) means f(g(x)). this means we have to use the two functions f(x) and g(x). In this case, we substitute the function of g(x) to the x- variable of the function of f(x). The two functions can be both polynomials or monomials. In this case, the answer to this problem is f(g(x)).

When it is operating properly, a chemical plant has a daily production rate that is normally distributed with a mean of 885 tons

-BARSIC- [3]

Answer:

The test statistic Z = 1.844 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

Yes he is right

The manager claims that at least 95 % probability that the plant is operating properly

Step-by-step explanation:

Explanation:-

Given data Population mean

μ = 885 tons /day

Given random sample size

n = 60

mean of the sample

x⁻ = 875 tons/day

The standard deviation of the Population

σ = 42 tons/day

Null hypothesis:- H₀: The manager claims that at least 95 % probability that the plant is operating properly

Alternative Hypothesis :H₁: The manager do not claims that at least 95 % probability that the plant is operating properly

Level of significance = 0.05

The test statistic

$Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{875 -885}{\frac{42}{\sqrt{60} } }$

$Z = \frac{-10}{5.422} = -1.844$

|Z| = |-1.844| = 1.844

The tabulated value

$Z_{\frac{0.05}{2} } = Z_{0.025} = 1.96$

The calculated value Z = 1.844 < 1.96 at 0.05 level of significance

Null hypothesis is accepted

Conclusion:-

The manager claims that at least 95 % probability that the plant is operating properly

You want to use square tiles to cover the top of a stepping stone you're making. The top is 24 inches by 20 inches. What is the

Alex777 [14]

You would use a 5 by 6 tile because you would find a common factor of 24 and 20 which is 4.

24 divided by 4 is 6
20 divided by 4 is 5

So the tiles used to cover the stone would be 6 by 5 tiles

Hope this helps :)
