In joint variation, the equation of variation holds the form 

e=k*fg, where k is the constant of variation. you can see how if either f or g increases, e increases as well, making e vary jointly with f and g. we are given the numbers e=4, f=2, and g=8, so when we input those into the general equations, 

4=k*2*8,
k=1/4

Answer:

The\ constant\ of\ variation\ is\ \frac{1}{4}.

Step-by-step explanation:

As given in the question

If e varies jointly with f and g.

i.e

e \propto fg

e = kfg

Where k is the constant of variation.

As

When e = 4, f = 2, and g = 8

Put in the above

4 = k × 2 × 8

4 = 16k

k = \frac{4}{16}

k = \frac{1}{4}

Therefore\ the\ constant\ of\ variation\ is\ \frac{1}{4}.

The probability that a lab specimen contains high levels of contamination is 0.12. A group of 4 independent samples are checked.
sergiy2304 [10]

Answer:

0.5996 is the probability that none contain high levels of contamination.

Step-by-step explanation:

We are given the following information:

We treat  lab specimen containing high levels of contamination as a success.

P( lab specimen containing high levels of contamination) = 0.12

Then the number of lab specimens follows a binomial distribution, where

P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 4

We have to find the probability that none of the lab specimen consist of high level of contamination.

We have to evaluate:

P(x = 0)\\= \binom{4}{0}(0.12)^0(1-0.12)^{(4-0)}\\= 0.5996

0.5996 is the probability that none contain high levels of contamination.

Solve for x: |x − 2| + 10 = 12 (1 point)
True [87]

Answer:

I think that would be 1

Step-by-step explanation:

Do everything in the lines before anything else. -2 becomes a 2 and then you add that with the 12 and divide 12 on both sides to get one.
