Answer:

x = 120

Step-by-step explanation:

Since they are supplementary, they add up to 180 degrees.

So, you can say x + x/2 = 180

Then, you would solve it like an algebra problem.

Multiply both sides by 2

2x + x = 360

Simplify

3x = 360

Divide both sides by 3

x = 120

True or false: a mosaic plot is useful for visualizing the relationship between a numerical and a categorical variable.

Ivahew [28]

It is false that for visualizing the relationship between a numerical and a categorical variable, a mosaic plot is useful. This is because the best plot to use for this kind of relationship is the side by side box plot.

Comparing the distribution of a numerical variable across the levels of a categorical variable is something we usually consider in this type of relationship.

The levels of one categorical variable by means of a quantitative variable is best compared by using the visual display called the side by side boxplot. By placing single boxplots adjacent to one another on a single scale, the side by side box plot is constructed.

7 + 2 (a -3) = -9 What is the answer do this?

Snezhnost [94]

Answer:

7+2(a-3)=-9

a= -5

Step-by-step explanation:

7+2(a-3)=-9

Distribute 2 through the parentheses

Example: 7+2a-6=-9

Next: 7+2a-6=-9

Subtract the numbers

1+2a=-9

Move constant to the right hand side and change its sighn 2a=-9-1

2a=-9-1

Calculate the difference 

2a=-10

Divide both sides of the equation by 2

Answer: a=- -5

On Saturday Lukas drove 4x - 5z On Sunday he drove 3x - 10. What is the difference in miles driven??

Makovka662 [10]

Answer:

The right answer is: Option C: x+5

Step-by-step explanation:

Let m1 be the miles Lukas drove on Saturday and Let m2 be the miles he drove on Sunday

$m_1 = 4x-5\\m_2 = 3x-10$

The difference can be found out by subtracting m2 from m1

minus sign will be distributed into the bracket and alike terms will be added or subtracted according to sign.

$m_1 - m_2 = 4x-5 - (3x-10)\\= 4x-5-3x+10\\= x+5$

The difference of miles driven is: x+5

Hence,

The right answer is: Option C: x+5
