Which of the following statements concerning the linear correlation coefficient are true?
I: If the linear correlation coefficient for two variables is zero, then there is no relationship between the variables.
II: If the slope of the regression line is negative, then the linear correlation coefficient is negative.
III: The value of the linear correlation coefficient always lies between –1 and 1.
IV: A linear correlation coefficient of 0.62 suggests a stronger linear relationship than a linear correlation coefficient of –0.82.

[tex]\sqrt[3]{488+24} \\[/tex]
Answer:
8
Step-by-step explanation:
First, add the values inside the radical
488+24 = 512
[tex]\sqrt[3]{512}[/tex] = x
This means that: [tex]x^{3}[/tex] = 512
Therefore, x must be equal to 8.
[tex]\sqrt[3]{512}[/tex] = 8
[[Please Explain]] The equation y - 2/3 = -2 (x - 1/4) is written in point-slope form. What is the equation in slope-intercept form? ³
O y = -2x - 1/6
O y = -2x + 7/6
O y = -2x + 5/12
O y = -2x - 11/12

Answer:
97.5
Step-by-step explanation:
Supplementary angles always add up to 180.
180 - 82.5 = 97.5
Answer:
97.5
Step-by-step explanation:
180-82.5=97.5
Supplementary means they add up to 180 degrees.
So just subtract 82.5 from 180. You get 97.5

Solve: 14+(5x-7)=19+3x
The answer is x=6, have a good day!
Answer:
[tex]x=6[/tex]
Step-by-step explanation:
First let's put our equation
[tex]14+(5x-7)=19+3x[/tex]
Let's drop our parenthesis[tex]14+5x-7=19+3x[/tex]
Subtract 3x from both sides[tex]14+2x-7=19[/tex]
Simplify[tex]7+2x=19[/tex]
Subtract 7 from both sides[tex]2x=12[/tex]
Divide both sides by 2[tex]x=6[/tex]

A rectangular community swimming pool is 31 2/3 meters long and 7 1/5 meters wide. The area around the swimming pool is covered with tiles. The area covered with tiles is 25% of the total area covered by the swimming pool. The total cost of the tiling is $712.50. What is the cost of the tiling per square meter?
Answer:
$12.50
Step-by-step explanation:
First, we find the area: 31 2/3 * 7 1/5 = 95/3 * 36/5 = 3,420/15 = 228 square meters. Then, we find the part that the tiles cover: 228 * 0.25 = 57 square meters. Now, we find the cost of the tiling per square meter by dividing the total cost by the total amount of tiling: $712.50 / 57 = $12.50. $12.50 will be your answer.

Answer:

Step-by-step explanation:
168+2^3+3^3-20=
Exponents
168+8+27-20
Addition
203-20
Subtraction
183
183 is the answer.
Answer:
10
Step-by-step explanation:
Using the process PEMDAS I got the answer 10.
168÷2^3+3^3-20
There are no parentheses so you solve the exponents first.
168÷8+9-20
Next, we do not multiply which makes division our second step.
This gives us 21+9-20.
Now we add 21+9 which gives us the sum of 30.
30-20 is equal to 10.
This is how I got my answer and I really hope this helps you
