<h2>
Answer:</h2>
When working with scientific data the average of a data set is called:
Mean of the data.
<h2>
Step-by-step explanation:</h2>
We know that in a given set of data the mean is calculated by finding the ratio of the sum of all the data points of the set to the total number of data points which is also known as the average of the data points.
Hence, the average of a data set is called :
Mean of data set
Answer:
The parallel lines are lines that are always at the same distance apart from each other and never touch. Also they must be drawn in the same plane.
Step-by-step explanation:
Consider the provided information.
The parallel lines are lines that are always at the same distance apart from each other and never touch. Also they must be drawn in the same plane.
The sketch that shows parallel lines is shown in figure.

Answer:
a) Distributive Property of Multiplication, b) Prioritizing the multiplication, c) Solving the Parentheses first and Reordering the expression d) Grouping the numbers that cancel each other
Step-by-step explanation:
On these expressions below, we have some ways to proceed with this resolution.
a) Distributive Property on Multiplication made possible the distribution of factor -2 (line 1)

b) Prioritizing the multiplication on line 1. By following the PEMDA acronym.
Parentheses, Exponents, Multiplication, Division, Adition.

c) Solve the Parentheses first and Reorder the expression

d) Grouping the numbers that cancel each other

A quarter = 0.25......200 quarters = 200(0.25) = $ 50
a dime = 0.10...150 dimes = 150(0.10) = $ 15
a penny = 0.01....300 pennies = 300(0.01) = $ 3
for a total of : 50 + 15 + 3 = $ 68
