Answer:

The correct statement is (B).

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

If there is any alteration in the value of one variable, the value of the other variable is altered in a fixed proportion. The correlation amid them is known as perfect correlation.

In statistics, a perfect positive correlation is represented by +1 and -1 indicates a perfect negative correlation.

Positive correlation is an association amid two variables in which both variables change in the same direction.

A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.

Negative correlation is a relationship amid two variables in which one variable rises as the other falls, and vice versa.

A correlation coefficient of 0 implies that there is no relationship between the two variables.

Thus, the correct statement is (B).

Answer:

(44.25/75)*100 or (44.25/3)*4

Step-by-step explanation:

Divide by the price of $44.25 by 75 (100% - 25%) and mulitily by 100

or $44.25 by 3 and multyply by 4. (25% is a quarter 1/4, so you need 4/4)

Solve and graph

oksano4ka [1.4K]

2r - 9 > -6
2r - 9 = -6
2r = 3
r = 3/2 = 1.5
r > 1.5

9x-5 < -41
9x-5 = -41
9x = -36
x = -36/9 = -4
x < -4

3x + 13 > 7
3x + 13 = 7
3x = -6
x = -6/3 = -2
x > -2

4x + 3 > -17
4x + 3 = -17
4x = -20
x = -20/4 = -5
x > -5

7x - 4 < 10
7x - 4 = 10
7x = 14
x = 14/7 = 2
x < 2

Answer:

x = 47

Step-by-step explanation:

So It most likely adds up to 180 degrees so.

x + 10 + x -10 + x - 10 + x + 6 = 180 (collect like terms)

4x -4 = 184 ( add 4 on both sides)

4x = 188 (divide 188 by 4)

x = 47

47 + 10 = 57 ----> x + 10

47 - 10 = 37 -----> x - 10

47 + 6 = 53 ------> x + 6
