If you subtract 11.1 from 8.3 you get 2.8

2.8 is your answer :)

Since Peru spends 8.3 and Israel spends 11.1

Subtract that and that's how many more Israel spends on the internet

Suppose that the value of r is 0.91 for the data set without the outlier. Which best predicts the value of r for the data with t

krok68 [10]

Answer: The correct answer would be 0.58.

The value of r of a set of data tells us how close the values are to the line of regression of the data. If you add in an outlier, it would make the overall r value of the points further from the line. In other words, it would go further from 1.

In this case, our initial r value was positive, so it makes sense to keep it positive. 0.58 would be the best choice.

Identify the properties used in step 1 and step 2 to solve the equation shown 2x+6=22 then discuss why those properties were use

Jet001 [13]

Answer:

In step 1 subtraction property is used and in step 2 division property is used.

Explanation:

We have the equation 2x + 6 = 22

Step 1

The subtraction property of equality tells us that subtracting the same number to each side of an equation gives us an equivalent equation

So subtracting 6 from both sides

2x + 6 - 6 = 22 - 6

2x = 16

Step 2

The division property of equality tells us that you can divide each side of an equation with the same nonzero number to produce an equivalent equation

So dividing each side by 2.

$\frac{2x}{2} =\frac{16}{2} \\ \\ x=8$
