7-9 you need to plug numbers into the formula y= mx+b where you plug the plots in M and B.

Step-by-step explanation:

I don't have a graph to plot 1-3 on but all you need to do is plot them and answer if they are parallel, perpendicular, or neither. (The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.) (In math, parallel means two lines that never intersect — think of an equal sign.) And if they don't fit either then its NEITHER

Tank 1: v = 1540 - 6m

Tank 2: v = 236 + 6m

109 minutes, less than two hours, since two hours is 120 minutes (60 minutes in one hour, times 2)

Set them equal to each other to find out when they will have the same number of gallons: 1540 - 6m = 236 + 6m

1304 = 12m
108.667 rounded to the nearest minute is 109 minutes, which is the answer.

What distribution of clothing should Nancy have for German males and females? Should she produce more small or large sizes, or should she have an even distribution of all sizes?

Answers

Answer: I sacrificed my answer for yours here u go love

Step-by-step explanation:

Nancy should produce more large sizes of the male clothing for German men since the data is skewed left, meaning there are more data values that lie on the right side, representing taller males. For women, she can have a roughly even distribution of sizes since the data set is symmetric.

Nancy should produce more large sizes of the male clothing for German men and for women, she can have a roughly even distribution of sizes since the data set is symmetric.

What is skewness in histogram?Skewness is the tendency for the values to be more frequent around the high or low ends of the x-axis.Skewness is the measure of the asymmetry of a histogram (frequency distribution). A histogram with normal distribution is symmetrical.

Given is to find what distribution of clothing should Nancy have for German males and females.

The shape of the data for German male adult heights is skewed left, but the shape of the data for female adult heights is close to symmetric. So, the distribution of the data is not the same. Each data set has the same minimum height of 145 centimeters. However, the maximum male adult height is 220 centimeters and the maximum female height is 185 centimeters. So, the range of values is not the same. The data for male adult heights has an outlier, but the data for female adult heights doesn't have any outliers.

Nancy should produce more large sizes of the male clothing for German men since the data is skewed left, meaning there are more data values that lie on the right side, representing taller males. For women, she can have a roughly even distribution of sizes since the data set is symmetric.

Therefore, Nancy should produce more large sizes of the male clothing for German men and for women, she can have a roughly even distribution of sizes since the data set is symmetric.

Answers

Answer:

185mm

Step-by-step explanation:

37 times 5 is 185

Answer:

185 mm

Step-by-step explanation:

There are 5 sides in a pentagon. Each side is 37 mm. Add 37 5 times or multiply 37 by 5.

37mm + 37mm + 37mm + 37mm + 37mm

The additive inverse of -7

Answers

Answer:

Step-by-step explanation:

An "additive inverse" refers to a number that when added to a specific number equals to "zero."

In the question above, the additive inverse of -7 is 7 because: -7 + 7 = 0

Other examples:

1. The additive inverse of 2 is -2 because: 2 + (-2) = 0

2. The additive inverse of -100 is 100 because: -100 + 100 = 0

3. The additive inverse of [tex]\frac{1}{2}[/tex] is -[tex]\frac{1}{2}[/tex] because: [tex]\frac{1}{2}[/tex] + -[tex]\frac{1}{2}[/tex] = 0

The additive inverse of -7 is equal to 7.

The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.

To determine the additive inverse of -7, we need to find the number that, when added to -7, results in zero.

To do this, we can multiply -7 by -1, which is the multiplicative inverse of 1. Multiplying a number by its multiplicative inverse always gives the additive inverse of that number.

So, -7 multiplied by -1 is:

-7 x -1 = 7

Therefore, the additive inverse of -7 is 7.

C. 7x - 3

D. 13x - 27/9

Answers

Answer:

The answer is B.

Step-by-step explanation:

The simplified expression is 7x - 27/9

What is expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

Constant: A constant is a fixed numerical value.Variable: A variable is a symbol that doesn't have a fixed value.Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

Given:

5(2x - 3) - 3(x + 4) / 9

=10x-15-3x-12/9

=10x-3x-15-12/9
