DedPeter [7]

Answer:

use own words

Step-by-step explanation:

An expression is just a mathematical phrase. In this tutorial, you'll learn about two popular types of expressions: numerical and algebraic expressions. A numerical expression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables.

in mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number)

In order to compare the real estate markets in Pittsburgh and Philadelphia, a realtor selected
melisa1 [442]

Answer:

The price of the homes in the Pittsburgh sample typically vary by about $267,210 from the mean home price of $500,000.

Step-by-step explanation:

The dotplots reveal that the variability of home prices in the Pittsburgh sample is greater than the variability of home prices in the Philadelphia sample. Therefore, the standard deviation of the home prices for the Pittsburgh sample is $267,210 rather than $100,740. The correct interpretation of this statistic is that the price of homes in Pittsburgh typically vary by about $267,210 from the mean home price of $500,000.

Answer:

21,800 milliliters

Step-by-step explanation:

Here's a trick.

King Henry Died By Drinking Chocolate Milk.

King = Kilo, Henry = Hecto, Died = Deka, By = Base (liters, grams, meters), Drinking = Deci, Chocolate = Centi, Milk = Milli.

This helps to remember the order so you can move the decimal over the proper amount of times.

If you are starting at the base, and need to move to milli, you will move the decimal place 3 places to the right.

So for 21.8 liters = 21,800 milliliters
