Subtract 3n and then divide by 4 and you get n= 4

we have

3n+16=7n

Solve for n

Subtract 3n both sides

3n+16-3n=7n-3n

4n=16

Divide by 4 both sides

4n/4=16/4

n=4

therefore

<u>the answer is</u>

n=4

A Game of Thrones fan predicts there is a 70% chance that her favorite character will survive the next season and a 75% chance t
zepelin [54]

Answer:

  • <em>The probability that the second favorite character will die given that the first favorite character dies is</em><u> 0.53</u>

  • <u>This kind of probability is called conditional probability</u>

Explanation:

Name the events and their probabiities:

  • Event  A: her favorite character will survive, so P (A) = 0.70

  • Event B: her her second favorite character will die, so P(B) = 0.75

  • Both characters will die ⇒ P (B and not A) = 0.16

You want to find P (B | not A).

That is the probability of the succes B (the second favorite character will die) given other event (not A or the first favorite character dies) is certain (it happens) and that is called conditional probability.

  • P (not A) is the complement probability of A, so P (not A) = 1 - P(A) = 1 - 0.7 = 0.3

So, you have P(B), P(not A) and want to find P (B | not A)

The definition of conditional probability is:

  • P (X | Y) = P (X and Y) / P (Y)

So, replacing with our terms, we get:

  • P ( B | not A) = P (B and not A) / P (not A) = 0.16 / 0.3 ≈ 0.53

What causes global convection current to form
hoa [83]

Answer:

Hope this helped :)

Step-by-step explanation:

Convection flows structure in light of the fact that a warmed liquid grows, getting less thick. The less-thick warmed liquid ascents from the warmth source. ... For example, a hot radiator warms the air promptly around it. The air ascends toward the roof, pulling cooler air down from the roof into the radiator to be warmed.

I don’t know how to simplify this equation
yanalaym [24]

Answer:

7^5

Step-by-step explanation:

According to the Product Rule for Exponents, \frac{a^m}{a^n} = a^{m-n}

a = 7

m = 9

n = 4

So,

\frac{7^9}{7^4} = 7^{9-4} = 7^5

So, the answer is 7^5.

Hope this helps!!!

Please mark me as brainliest!!!
