Answer:

C. All real numbers.

Step-by-step explanation:

We have been given a function f(x)=3^x. We are asked to find the domain of our given function.

We know that domain of a function is all values of x for which a function is real and defined.

We know that the domain of an exponential function is all real values of x that is (-\infty,\infty).

Since our given function is an exponential function, therefore, domain of our given function is all real numbers.

WARRIOR [948]
$72 - $30 = $42

It increased $42.



Now take this number and divide by the original number (first):

42 ÷ 30

This is 1.4, let's convert this to a percentage.
We now times it by 100



1.4 × 100

Here is the histogram of a data distribution. What is the shape of this distribution.
tankabanditka [31]

Answer:

Hey there!

I think your answer would be unimodal skewed. This graph only has one maxima, thus it can't be bimodal. However, it's not symmetric, meaning that it is skewed.

Hope this helps :)

Use the Central Limit Theorem to find a mean given a probability Question A video game company sells an average of 132 games a m
aev [14]

Answer:

The number of games must a store sell in order to be eligible for a reward is 135.

Step-by-step explanation:

Let the random variable <em>X</em> represent the number of video games sold in a month by the sores.

The random variable <em>X</em> has a mean of, <em>μ</em> = 132 and a standard deviation of, <em>σ</em> = 9.

It is provided that the company is looking to reward stores that are selling in the top 7%.

That is, P (\bar X > \bar x) = 0.07.

The <em>z</em>-score related to this probability is, <em>z</em> = 1.48.

Compute the number of games must a store sell in order to be eligible for a reward as follows:

z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}

\bar x=\mu+z\cdot \sigma/\sqrt{n}

   =132+1.48\times (9/\sqrt{36})\\\\=132+2.22\\\\=134.22\\\\\approx 135

Thus, the number of games must a store sell in order to be eligible for a reward is 135.
