(Literal equations) The formula for the volume of a cylinder is V = πr^2h. Solve V = πr^2h for h, the height of the cylinder. A.
Kobotan [32]

Answer:

C

Step-by-step explanation:

Given

V = πr²h

Isolate h by dividing both sides by πr²

\frac{V}{\pi r^2} = h → C

6. Assume that a component passes a test is 0.85 and that components perform independently. What is the probability that the thi
Tanzania [10]

Answer:

3.90% probability that the third failure will occur on the tenth component tested

Step-by-step explanation:

For each component, there are only two possible outcomes. Either it fails, or it does not fail. Components perform independently. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

Assume that a component passes a test is 0.85

So they fail with probability of p = 1 - 0.85 = 0.15

What is the probability that the third failure will occur on the tenth component tested

First 9 components: Two failures, that is, P(X = 2) when n = 9.

10th component: Failure with probability 0.15.

So

P = 0.15P(X = 2)

In which

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 2) = C_{9,2}.(0.15)^{2}.(0.85)^{7} = 0.2597

So

P = 0.15P(X = 2) = 0.15*0.2597 = 0.0390

3.90% probability that the third failure will occur on the tenth component tested

PLEASE HELP I NEED THIS DONE ASAP! ILL MAKE BRAINLIST
Brrunno [24]

Answer:

i) 7x + 8 = -90

<=> 7x = -98

<=> x = -98/7

<=> x = -14

ii) 5y - 4 = 2y - 25

<=>3y = -21

<=> y = -21/3

<=> y = -7

iii) 4(p + 3) = 36

<=> p + 3 = 36/4

<=> p + 3 = 9

<=> p = 9 - 3

<=> p = 6

iv) 2 (4f + 3) = 3 (2f + 6)

<=> 8f + 6 = 6f + 18

<=> 2f = 12

<=> f = 12/2

<=> f =6

Hope this helps!

:)
