What is the MAD of the data set?<br><br> {10, 9, 16, 5, 10}
Oksanka [162]
First, you'd find the mean of all the numbers by doing 10+9+16+5+10 = 50/5 = 10. Second, you'd subtract all values from the mean by doing 
16 - 10 = 6
10 - 10 = 0
10 - 10 = 0
10 - 9 = 1
<span>10 - 5 = 5
Lastly, finding the mean of all 5 numbers would be, 2.4! Hope this helps!! :D</span>

State whether the lines are parallel, perpendicular, coinciding, or neither: 6x+3y=–15 and y–3=–2x
lianna [129]

Answer:

Parallel

<u>Step-By-Step Explanation:</u>

Put the Function in Slope Intercept Form and Find the Slope of 6x+3y = 15

6x+3y = 15

3y = -6x + 15

3y/3 = -6x/3 + 15/3

y = -2x + 5

<u>We can see that the slope of 6x+3y = 15 is -2</u>

Put the Function in Slope Intercept Form and Find the Slope of y–3=–2x

y–3=–2x

y = -2x + 3

Here are our two Functions In Slope Intercept Form

y = -2x + 5

y = -2x + 3

<u>Remember the m = slope and the b = y-intercept</u>

y = mx + b

y = -2x + 5

y = -2x + 3

------------------------------------------------------------------------------------------------------

We can see both equations have the same slope of -2 so this means they could be parallel because parallel functions have the same slope but coinciding functions have the same slope too. To tell if the two functions are coinciding, the functions need to have the same slope and the same y-intercept. Looking at the two functions, we can see they have the same slope of -2 but their y-intercept are different so this makes the two functions parallel.

The box plots represent the ages of pennies in two 50-cent rolls. By looking at the plots, Beth says that the two means are abou
Jlenok [28]

Answer:

The correct option is D

D) She may not be correct because means cannot be determined from the box plots

Step-by-step explanation:

The question is incomplete because the box plots are not attached in the question. I've attached the box plots of this question at the bottom.

The box plot, also know as box and whisker plot, displays only five type of values, which are:

  1. Minimum value
  2. First Quartile
  3. Median
  4. Third Quartile
  5. Maximum value

Mean cannot be determined by just lookin at the box plots. To find the mean, we need to know the values of data and total number of values.

As mean cannot be determined from the box plot, correct option is D
