HELPPPP ASPAPPPP PLEASEEEE !!!!!
Gnesinka [82]

Answer:

x^(1/3)

Step-by-step explanation:

let's start with x^2 / x^(2/3), then we'll move on the the 4th root

when dividing exponents with the same base, we subtract the exponents:

x^2 / x^(2/3) = x^(2 - 2/3) = x^(4/3)

the fourth root of x^4/3 can become x^(4/3 * 1/4)

(i used the formula x^(m/n) = nth root of x^m)

x^(4/3 * 1/4) = x^1/3

hope this helps! <3

Question 4 of 10, Step 1 of 1 1/out of 10 Correct Certify Completion Icon Tries remaining:0 The Magazine Mass Marketing Company
erastovalidia [21]

Answer:

0.0105 = 1.05% probability that no more than 3 of the entry forms will include an order.

Step-by-step explanation:

For each entry form, there are only two possible outcomes. Either it includes an order, or it does not. The probability of an entry including an order is independent of any other entry, which means that the binomial probability distribution is used 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.

The Magazine Mass Marketing Company has received 16 entries in its latest sweepstakes.

This means that n = 16

They know that the probability of receiving a magazine subscription order with an entry form is 0.5.

This means that p = 0.5

What is the probability that no more than 3 of the entry forms will include an order?

At most 3 including an order, which is:

P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

In which

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

P(X = 0) = C_{16,0}.(0.5)^{0}.(0.5)^{16} \approx 0

P(X = 1) = C_{16,1}.(0.5)^{1}.(0.5)^{15} = 0.0002

P(X = 2) = C_{16,2}.(0.5)^{2}.(0.5)^{14} = 0.0018

P(X = 3) = C_{16,3}.(0.5)^{3}.(0.5)^{13} = 0.0085

Then

P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0 + 0.0002 + 0.0018 + 0.0085 = 0.0105

0.0105 = 1.05% probability that no more than 3 of the entry forms will include an order.

-2.3 + 10.8 + (-8.4)
spayn [35]

Answer:

.1

Step-by-step explanation:

Try and take it step by step.

-2.3 + 10.8 + (-8.4)

First let's rearrange and combine the negatives.

-2.3 + (-8.4) + 10.8

-2.3 + (-8.4) = - 10.7

Let's rewrite

10.8 - 10.7  and solve!

10.8 - 10.7 = .1
