magnitude = sqrt(6^2+4^2)

= sqrt ( 36+16)

=sqrt (52) = 7.2

angle = tan^-1(6/4) = 56 degrees

A beautician sees clients each day to paint full sets of nails. The function g(x) represents the number of finger nails painted,

Yes, the input and output are both possible.

Reason~

Given that the possible solution is (20,20),

Input = x = 20

Output = x = 20

Thus, g(20) = 20, which is clearly possible.

Hope this helps :)

Irrational numbers are numbers with infinite decimals values that are not repeating (ex. Pi 3.14159265....). Whole numbers don’t have decimal values in the first place, so all whole numbers are therefore rational.

Keep in mind that just because a number has decimal values doesn’t mean it’s irrational (ex. 4.5 is a rational number). It needs to have infinite non-repeating decimal values to be irrational.

A pet store sells aquariums that are rectangular prism the volume v of the aquarium is given by the formula V equals l w h where

brilliants [131]

For this case we have:

The volume of the aquarium, given by a rectangular prism, is:

$V = l * w * h$

Where:

l: It is the length of the aquarium

w: It is the width of the aquarium

h: It's the height of the aquarium

If we want to clear the height of the aquarium, we must divide both sides of the volume equation between l * w, so we have:

$\frac{V}{(l*w)}=\frac{l*w*h}{(l*w)}$

$\frac{V}{(l*w)}=h$

Thus, the height of the aquarium is given by: $h=\frac{V}{(l*w)}$

Answer:

$h=\frac{V}{(l*w)}$

What will happen (other things being equal) if you increase the sample size used to construct a given confidence interval?

Bumek [7]

Answer:

So if you increase the sample size used to construct a given confidence interval, the confidence interval will be narrower, that is, more precise.

Step-by-step explanation:

The sample size is important to find the margin of errror of a confidence interval.

The margin of error is given by a formula in the following format:

$M = \frac{c*s}{\sqrt{n}}$

In which c is the critical value(depends on the distribution used, can be T or Z), s is the standard deviation(of the sample or the population) and n is the size of the sample.

As n increases, M decreases, which leads to a lower margin of error.

The lower the margin of error, the more precise the interval is.

So if you increase the sample size used to construct a given confidence interval, the confidence interval will be narrower, that is, more precise.
