Answer:

$b = \frac{7}{12}$

Step-by-step explanation:

$b + \frac{2}{3} = 1\frac{1}{4}\\\\b = 1\frac{1}{4} - \frac{2}{3}\\\\b = \frac{5}{4} - \frac{2}{3}\\\\b = \frac{5(3)}{4(3)} - \frac{2(4)}{3(4)}\\\\b = \frac{15}{12} - \frac{8}{12}\\\\b = \frac{7}{12}$

Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on

FinnZ [79.3K]

The question is incomplete! Complete question along with answers and step by step explanation is provided below.

Question:

(a) Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on each trial. Under what conditions is it appropriate to use a normal approximation to the binomial? (Select all that apply.)

nq > 10

np > 5

p > 0.5

np > 10

p < 0.5

nq > 5

(b) What is the probability of "12" or fewer successes for a binomial experiment with 20 trials. The probability of success on a single trial is 0.50. Use the normal approximation of the binomial distribution to answer this question. (Round your answer to four decimal places.)

Answer:

(a) The correct options are np > 5 and nq > 5

(b) P(x ≤ 12) = 0.8133

Step-by-step explanation:

1. A-Tunes requires a membership fee of $12 a month and $1 for each download.

matrenka [14]

<h3>Answer:</h3>

After 16 downloads the charges will equal each other.

<h3>Step-by-step explanation:</h3>

First set up an equation

x = Downloads

12 + 1x = 5 + 1.5x

Solve

12 + 1x = 5 + 1.5x <- Rewrite your equation

-5 -5 <- Subtract 5 from both sides

8 + 1x = 1.5x <- Simplify

-1x -1x <- Subtract 1 from both sides

8 = 0.5x <- Simplify

8 = 1/2x <- Convert 0.5 to a fraction to make the next step easier

16 = x <- Multiply both sides by 2 to divide by

a fraction

Select all of the following that are ordered pairs of the given function.

Tatiana [17]

F(x) is the same as y.......so basically ur subbing in ur points into the equation to see if it comes out equal.

f(x) = 3 - 2x.....(-2,-1)....x = -2 and f(x) = -1
-1 = 3 - 2(-1)
-1 = 3 + 2
-1 = 5.....this is not true, so it is not a solution

and that is how to do this problem.....

(-1,5)......this IS a solution
(0,3)......this IS a solution
(1,0)...this IS NOT a solution
(2,-1)...this IS a solution
