2n-15=53
You need to get n by itself. To do that we need to simplify the left hand side of the equation. To do so, we move everything away from n. First add 15 to both sides to eliminate it on the left side.
2n-15+15=53+15
2n=68
next divide by 2 to solve for n
2n/2=68/2
n=34

First add 15 to both sides:

2n = 68

Then divide each side by two.

n = 34

Arrange in descending order 1/2, 3/4, 2/3

Anastaziya [24]

Answer:

The question is asking which numbers are larger with respect to one another. An easy way to do this is to convert to decimals, or just memorize it. 1/2=0.5, 3/4=0.75, 2/3=0.666666. So descending order (largest to smallest) 3/4, 2/3, 1/2.

Answer:

P(N = n) = $(1-P)^{n-1} \times P$

Step-by-step explanation:

to find out

Find the PMF PN (n)

solution

PN (n)

here N is random variable

and n is the number of times

so here N random variable is denote by the same package that is N (P)

so here

probability of N is

P(N ) = Ф ( N = n) .................. 1

here n is = 1, 2,3, 4,...................... and so on

so that here P(N = n) will be

P(N = n) = $(1-P)^{n-1} \times P$
