Answer:

Step-by-step explanation:

The answer is C (0.02).

Correlation coefficient is between 1 and -1.

1 is strong positive correlation, while -1 is strong negative correlation. In grading the options, 0.02 is closer to zero which is no correlation.

<h3>Answer: C) 0.02</h3>

====================================================

Explanation:

Any r values close to -1 or +1 represent strong correlation. Specifically, anything close to r = -1 is strong negative correlation, while anything close to r = 1 is strong positive correlation.

As you move closer to r = 0, the correlation weakens. The value r = 0.02 in choice C is the closest to r = 0, so this correlation is the weakest among the group of other r values.

If 10% of a number is 7, what is 80% of the number?

Zanzabum

Answer:

Step-by-step explanation:

Note that 80% is 8 times 10%.

Thus, we could start with "If 10% of a number is 7" and multiply both quantities by 8: "80% of a number is 56."

Think:

10% of a number is 7,

20% is 14,

50% is 35,

70% is 49, and

80% is 56.

HELP PLS ITS ALGEBRA 1

Georgia [21]

Answer:

$- \frac{2}{6}$

Step-by-step explanation:

Use distributive property to simplify both sides.

$\frac{1}{6} (1 - 6x) = - \frac{1}{3} ( 6x + \frac{1}{2} )$

Use the Golden Rule of Algebra: (What we do to one side, we must do to the other).

$\frac{1}{6 } - x = - 2x - \frac{1}{6}$

$\frac{1}{6} = - x - \frac{1}{6}$

$\frac{2}{6 } = - x$

$x = - \frac{2}{6}$

Jessica, Chau, and Kareem sent a total of 84 text messages during the weekend. Kareem sent 4 times as many messages as Chau. Jes

swat32

Answer:

Number of messages sent by Chau = 15

Number of messages sent by Kareem = 4 * 15 = 60

Number of messages sent by Jessica = 15 - 6 = 9

Step-by-step explanation:

Let number of messages sent by Chau = c

Number of messages sent by Kareem = 4 times as Chau

= 4 * c = 4c

Number of messages sent by Jessica = 6 fewer messages than Chau

= c - 6

Total messages = 84

c + 4c + c - 6 = 84 {Combine like terms}

6c - 6 = 84 {Add 6 to both sides}

6c = 84 + 6

6c = 90 {Divide both sides by 6}

c = 90/6

c = 15

Number of messages sent by Chau = 15

Number of messages sent by Kareem = 4 * 15 = 60

Number of messages sent by Jessica = 15 - 6 = 9
