How do find you equivelant expressions?

1 answer:

4 0

You'll have to start off by finding the variables. Ex:

3(x + 3) - 2(x + 3)

As you can see here, the two similar variables are x. By using the distributive property, you will get this:

3x + 9 - 2x + 6

Next, you'll want to subtract the two variables, since 2x has a - in front of it:

1x + 9 + 6

or

x + 9 + 6

Then, you want to add the two numbers without the variable:

x + 15

Your answer is x + 15.
Hopefully that helped! :)

Answer: 0.1854

Step-by-step explanation:

Given : Suppose that a particular candidate for public office is in fact favored by 48% of all registered voters in the district.

Let $\hat{p}$ be the sample proportion of voters in the district favored a particular candidate for public office .

A polling organization will take a random sample of n=500 voters .

Then, the probability that p will be greater than 0.5, causing the polling organization to incorrectly predict the result of the upcoming election :

$P(\hat{p}>0.5)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.5-0.48}{\sqrt{\dfrac{0.48(0.52)}{500}}})\\\\=P(z>0.8951)\ \ [\because\ z=(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(z\leq0.8951)\ \ [\because\ P(Z>z)=1-P(Z\leq z)]\\\\ = 1-0.8146=0.1854$
