How can you use models to evaluate and compare expressions

Relative frequencies are calculated as totals.

Here, we have,

In statistics, relative frequency refers to the proportion or percentage of times a particular value or category appears in a dataset relative to the total number of observations or data points.

It is a way to express the frequency of a value or category in relation to the whole dataset.

To calculate the relative frequency, you divide the frequency (number of times a value or category occurs) by the total number of observations or data points.

This gives you the proportion or percentage of occurrences relative to the total.

For example, if you have a dataset of 100 observations and a specific value appears 20 times, the relative frequency of that value would be 20/100 or 0.20, which is 20%.

So, relative frequencies are calculated as totals by comparing the specific frequency of a value or category to the total number of observations in the dataset.

Answer:

We have to find the value of without division.

We have to convert   into simplest form

To convert into simplest form, Find the hcf of 1.016 and 4.064 and than divide the numerator and denominator by hcf

The hcf of  1.016 and 4.064 is 1016

=  

{We can remove the decimals directly if numerator and denominators are like decimals}

Divide Numerator and denominator by 1016

=0.25

The answer is 0.25

Hence we get 0.25 without by actual division.

Answer:

4.45833333

Step-by-step explanation:

Answer:

87,120 ft²

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Surface area of the Empire State building replica = 45 square feet

Scale factor = 44

2. What is the surface area of the actual Empire State Building in square feet?

For answering the question, we will make the following calculations:

45 square feet = 9 feet * 5 feet or,

45 square feet = 10 feet * 4.5 feet, or,

45 square feet = 20 feet * 2.25 feet.

Now, let's apply the scale factor to all of these probable lengths of the sides of the surface area of the replica, as follows:

(9 *44) * (5 * 44) = 396 * 220 = 87,120 ft²

(10 * 44) * (4.5 * 44) = 440 * 198 = 87,120 ft²

(20 * 44) * (2.25 * 44) =  880 * 99 = 87,120 ft²

As we proved, no matter what are the lengths of the sides of the surface area of the replica. after applying the scale factor, the result is the same: 87,120 ft²
