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.

90<-30p+15 how do you solve this

Alenkinab [10]

<em>*To solve an inequality, it's the same as if you were solving an equation: Isolate the desired variable to one side to solve.</em>

Firstly, subtract 15 on both sides: $75$

Next, you are going to divide both sides by -30. Since you are dividing by a <u>negative,</u> you are going to flip the inequality symbol. <u>Your final answer will be: $-\frac{5}{2}>p$ </u>

Which expression can be used to find the value of expression below -(7/10) + 2/8 + 1/10 - (4/8)

maks197457 [2]

Answer:

(-17)/20

Step-by-step explanation:

Simplify the following:

-7/10 + 2/8 + 1/10 - 4/8

The gcd of 2 and 8 is 2, so 2/8 = (2×1)/(2×4) = 2/2×1/4 = 1/4:

-7/10 + 1/4 + 1/10 - 4/8

The gcd of -4 and 8 is 4, so (-4)/8 = (4 (-1))/(4×2) = 4/4×(-1)/2 = (-1)/2:

-7/10 + 1/4 + 1/10 + -1/2

Put -7/10 + 1/4 + 1/10 - 1/2 over the common denominator 20. -7/10 + 1/4 + 1/10 - 1/2 = (2 (-7))/20 + 5/20 + 2/20 - 10/20:

(2 (-7))/20 + 5/20 + 2/20 - 10/20

2 (-7) = -14:

(-14)/20 + 5/20 + 2/20 - 10/20

-14/20 + 5/20 + 2/20 - 10/20 = (-14 + 5 + 2 - 10)/20:

(-14 + 5 + 2 - 10)/20

-14 + 5 + 2 - 10 = (5 + 2) - (14 + 10):

((5 + 2) - (14 + 10))/20

5 + 2 = 7:

(7 - (14 + 10))/20

Need help finding slop please!

Soloha48 [4]

The slope is
1. Find ordered pairs ( 1 , -4 ) ( 3, 3)
The formula is
M= y2 - y1
_____
X2- X1
2. Replace the numbers
M = 3 - 4.
———
1-3
Subtract
3. You get -1/-2
4. Divide you get 0.5
( but if you need rise and run use -1/-2) rise top run bottom
Slope is 0.5 I think
Hope this helps here a picture of my lesson.
