Answer:
3/4
Step-by-step explanation:
it's for sure 3/4!!!!!
We are given a line with the following data:
r-value = 0.657 (r)
standard deviation of x-coordinates = 2.445 (Sx)
standard deviation of y-coordinates = 9.902 (Sy)
We are asked to find the slope of the line up to 3 decimal places.
To find the slope of the line, based on the data that we have, we can use this formula:
slope, b = r * (Sy / Sx)
substitute the values to the formula:
b = 0.657 * ( 9.902 / 2.445 )
Solve for the b.
Therefore, the slope of the line is
b = 2.66078, round off to three decimal places:
b = 2.661 is the slope of the line.
Answer:
k = 6
Step-by-step explanation:
Using synthetic division, we find the remainder from the division to be ...
remainder = 4k+2
Then we need to find k such that ...
4k +2 = 26
4k = 24 . . . . subtract 2
k = 6 . . . . . . divide by 4
The value of k is 6.
