Answer:

z<2

Step-by-step explanation:

-2(z + 5) + 20 > 6

Subtract 20 from each side

-2(z + 5) + 20 -20 > 6-20

-2(z + 5) > -14

Divide each side by -2 remembering  to flip the inequality

-2/ -2(z + 5) < -14/-2

z+5 < 7

Subtract 5 from each side

z+5-5 < 7-5

z<2

First you need to distribute
then you’d have -2z - 10 + 20 > 6
-2z + 10 > 6
-2z > 6 - 10
-2z > - 4
z < 2

Define linear relationship​
-Dominant- [34]

Answer:

A linear relationship (or linear association) is a statistical term used to describe a straight-line relationship between two variables. Linear relationships can be expressed either in a graphical format or as a mathematical equation of the form y = mx + b. Linear relationships are fairly common in daily life.

A negative value of r means that:
tatuchka [14]

Answer:

(d.) Those who score high on one variable tend to score low on the other.

Step-by-step explanation:

A negative value of correlation coefficient (r) shows a relationship between two variables such that as one variable increases, the other decreases. It shows the inverse relationship between two variables with the dependence determined by the value of the correlation coefficient (r).

It can be observed that for graphs with negative slope, the correlation coefficient (r) is similarly negative. This speaks about its relationship too.

The correlation coefficient being negative doesn't mean the relationship between the two variables in question is bad, it just means that the correlation relationship is inverse (still dependent). A perfectly negative correlation is -1.

Write an equation with a variable AND solve it. Mario read 72 pages of his book in class and 13 pages per night, n, until he rea
coldgirl [10]

9514 1404 393

Answer:

  72 +13n = 163

  7 nights

Step-by-step explanation:

At 13 pages per night, Mario will read 13n pages in n nights. That plus the pages already read will total 163:

  equation: 13n +72 = 163

__

To solve this, we can subtract 72, then divide by the coefficient of n.

  13n = 91 . . . . . . subtract 72 from both sides

  n = 7 . . . . . . . . divide both sides by n

Mario read 7 nights.
