Answer:
6w^3
Step-by-step explanation:
It can't be any answer with cubed in it because that would be volume. So, A and C magically vanish. If we know that the length of a cube is w that means that all sides are w. There are six faces on a cube. If we want to find surface area we will have to add up the area of all faces. the area of one face will be w^2. We multiply that number by six and we get 6w^3.
Answer:
Probability that the sample variance exceeds 3.10 is less than 0.05%.
Step-by-step explanation:
We are given that a process produces batches of a chemical whose impurity concentrations follow a normal distribution with a variance of 1.75.
Also, a random sample of 20 of these batches is chosen.
The probability distribution that we will used here is of Chi-square distribution, i.e.;
~
where,
= sample variance
= population variance = 1.75
n = sample of batches = 20
So, probability that the sample variance exceeds 3.10 is given by = P(
> 3.10)
P(
> 3.10) = P(
>
)
= P(
> 59.62) = P(
> 59.62) = Less than 0.05%
From chi-square table we can observe that Probability that
is greater than is less than 0.05%.
So, the probability that the sample variance exceeds 3.10 is less than 0.05%.

Answer:
101/200
Step-by-step explanation:
Take the decimal out an put the number over 1000.
= 505/1000
Find a common denominator
505/5 = 101
1000/5 = 200
Reduce
505/1000 = 101/200
