-22.75
-144
Answer:
d) -144
Step-by-step explanation:
A-True
B-False
The statement the line best fit has been an estimate and cannot be calculated. Therefore, the given statement is true.
The best fit line can be defined as the line created by connecting the majority of the points in a scatter plot. Depending on the scatter plot's points, the best fit line may take the form of a straight line or a curve.
The scatter plot's relationships between the variables are better understood when the best fit is used. The maximum scattered point serves as the line's best fit's pivot point.
The predicted line that best matches the plot depends on whether the straight-line equation fits it. As a result, it has not been able to measure the line of optimum fit.
Therefore, the given statement is true.

Answer:
a
Step-by-step explanation:
solve x^2-6x= -25
Answer: x = 3 ± 4i
Step-by-step explanation:
x² - 6x + 25 = 0
a=1 b= -6 c=25
Use Quadratic Formula:
= 3 ± 4i
Answer:
x= 3+4i , x= 3-4i
Step-by-step explanation:
x^2-6x= -25
To solve for x we need to make right hand side
So add 25 on both sides
Now apply quadratic formula
From the given equation a=1, b=-6 and c=25
Plug in all the values in the formula
We know
So equation becomes
Divide by 2
x= 3+-4i
So x= 3+4i , x= 3-4i
