Dimas [21]3 years ago

8 0

Answer:

A. The mean will increase.

Step-by-step explanation:

The mean is the average of the numbers. You just add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

84 + 75 + 76 + 80 + 48 + 75 = 438

438 / 6 = 73

mean = 73

The outlier is 48, so when you remove it, there will now be only five numbers in the set, and the mean will increase in size.

84 + 75 + 76 + 80 + 75 = 390

390 / 5 = 78

NEW mean (without the outlier) : 78

How do I complete this chart?

Mrac [35]

Answer:

Step-by-step explanation:

You would first have to plug in for x, (which is already given). After plugging in for x, you would need to solve the equation to get y.

Once you have both x and y, you will have your (x,y)

For example: (given x value = -5)

$f(x) = -|x - 5| -4\\f(-5) = -|(-5) - 5| - 4\\f(-5) = -|-10| - 4\\f(-5) = -10 - 4\\f(-5) = -14\\f(-5) = y = -14\\\\$

so:

x = -5

y = -14

( -5, -14)
