Answer:

20cm

Step-by-step explanation:

Let s = the length of the base

Let 4s = the length of the height

V = BH Since the base is a square, B = s2

V = s2 H

500 = s2(4s)

125 = s3

s = 5 cm

4s = 20 cm - the height

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.
