The answer to your problem is........... 60..... i think :)
Using correlation coefficients, it is found that the -0.63 correlation between number of absences and final exam score means that there is a strong negative correlation between number of absences and final exam score.
<h3>What is a correlation coefficient?</h3>
It is an index that measures correlation between two variables, assuming values between -1 and 1.
If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
In this problem, the correlation is of -0.63, hence:
It means that that there is a strong negative correlation between number of absences and final exam score.

Answer:
Last one at the bottom
Step-by-step explanation:
Recall that for a function to be valid, each input (x-value) must give exactly one unique output (y-value). If we find that any x-value gives more than one y-value, then it is not a function.
Option 1: x = 3 gives y = 2 and y = -2 (not a function)
Option 2: x = 5 gives y = 2 and y = 8 (not a function)
Option 3: x = 3 gives y = 4 and y = 5 (not a function)
Option 4: each x-value gives only one possible y-value (this is a function)
Answer:
10x²+36x+18
Step-by-step explanation:
You must make a box and distribute each number in the first parantheses to each number in the second parantheses.
<u>2x | 10x</u>²<u> | 6x </u>
<u>6 | 30x | 18 </u>
5x 3
So first take triple 3 which would be 3+3+3 or 3x3.
Then take double 8 which would be 8+8 or 8x2.
So all you need to do is write it in the associative property.
So it would look like this:
(3x3)+(8x2)= 25
9 + 16
Because 3x3 is 9 and 8x2 is 16 so you just need to add them to get the product.
