Answer and explanation:

1. It is commonly referred to as the arithmetic average: the mean measure of central tendency is also referred to as the arithmetic mean or arithmetic average or just average.

It is algebraically defined (that is, there is an equation you can use to calculate its value): the mean can be represented by the algebraic equation

a1+a2+a3...ai/n

2. There can be more than one median where there are an even number of data points and not odd number, in which the two middle number are divided by 2

It can be found when there are undetermined scores: median can be found with undetermined scores

3. It corresponds to an actual score in the data: the mode is an actual value in the data that appears more frequently than other values

There can be more than one: there can be more than one mode(bimodal,trimodal,multimodal) where 2 or more values appear the same number of times

The square length of hypotenus (the side lenght that sees 90 degrees) is equal to sum of square length of side lengths

2^2 + 4^2 = x^2

4 + 16 = x^2

20 = x^2 and x = 2√(5)

Math- Look at the picture below i will mark you as brainliest if you answer correctly.
densk [106]

Answer:

A

Step-by-step explanation:

Substitue 15 into the x value and complete the equation.

This is because 2,280 is the original distance. 15 would be the hours and 60 would be how many miles per hour. So we multiply 15 and 60 and get 900, this is how many total miles they have driven. But when we subtract that number from 2,280, and we get 1,380, this is how many miles they have left.
