Yes, we claim that the two ratios are proportional.

<h3>Proportion</h3>

Proportion is an equality between two ratios. These ratios are made up of two real integers. In a proportion, when there is an equality, both ratios have to be equivalent to the other. Equivalent ratio is when both division results are equal.

— To find out if the equality between these two given ratios is true, let's just: divide the numerator by the denominator.

3/8 = 3 ÷ 8 = <u>0,375</u>

24/64 = 24 ÷ 64 = <u>0,375</u>

Therefore, we see that the results of these ratios are the same. So these two ratios are proportional. 3/8 = 24/64

A bottle of medicine contains 40 doses. How many doses are in 3 1/3 bottles?

sdas [7]

Hi there! So, there are 40 doses in 1 bottle. To find out the number of doses in 3 1/3 bottles, we have to multiply both numbers together. 3 1/3 as an improper faction is 10/3. 40/1 * 10/3 is 400/3 or 133 1/3 in simplest form. There are 133 1/3 doses of medicine in 3 1/3 bottles.

Standard deviation of a normal data distribution is a _______. Group of answer choices

FrozenT [24]

Answer:

Standard deviation of a normal data distribution is a measure of data dispersion.

Step-by-step explanation:

Standard deviation is used to measure dispersion which is present around the mean data.

The value of standard deviation will never be negative.

The greater the spread, the greater the standard deviation.

Steps-

1. At first, the mean value should be discovered.

2.Then find out the square of it's distance to mean value.

3.Then total the values

4.Then divide the number of data point.

5.the square root have to be taken.

Formula-

SD= $\sqrt{\frac{(\sum{x-x)^2} }{n-1}$

Advantage-

It is used to measure dispersion when mean is used as measure of central tendency.
