Answer:
C. Determine how many feet −55 feet is below zero feet.
D. Determine how far −55 is from zero on the number line
Step-by-step explanation:
Determine how many feet −55 feet is below zero feet.
This will give us the answer of 55feet , and the absolute value of -55 is 55.
0--55= 0+55 = 55
Determine how far −55 is from zero on the number line
This will also give me us 55 feet because the distance from 0 to -55 is 55
I.e. 0--55= 0+55 = 55

<em>Key Differences Between Covariance and Correlation
</em>
<em>The following points are noteworthy so far as the difference between covariance and correlation is concerned:
</em>
<em>
</em>
<em>1. A measure used to indicate the extent to which two random variables change in tandem is known as covariance. A measure used to represent how strongly two random variables are related known as correlation.
</em>
<em>2. Covariance is nothing but a measure of correlation. On the contrary, correlation refers to the scaled form of covariance.
</em>
<em>3. The value of correlation takes place between -1 and +1. Conversely, the value of covariance lies between -∞ and +∞.
</em>
<em>4. Covariance is affected by the change in scale, i.e. if all the value of one variable is multiplied by a constant and all the value of another variable are multiplied, by a similar or different constant, then the covariance is changed. As against this, correlation is not influenced by the change in scale.
</em>
<em>5. Correlation is dimensionless, i.e. it is a unit-free measure of the relationship between variables. Unlike covariance, where the value is obtained by the product of the units of the two variables.

Answer:
13sqrt(2) units
Step-by-step explanation:
LM² = 7² + 17²
LM² = 338
LM = sqrt(338)
LM = 13sqrt(2)
sqrt: square root
Answer:
c. ( 5, 3)
Step-by-step explanation:
6x-27=4x-17
6x-27-4x=4x-17-4x
2x-27=-17
2x-27+27=-17+27
2x=10
x=10/2
x=5
y=6(5)-27
y=30-27
y=3
