Answer:
The answer is 90 4/10
Step-by-step explanation:
if u divide 4 from 10 u will get 0.4
Y= (-10+√92)/4 = (-10+2√23)/2 = -5+ √23
or
y= (-10-√92)/4=-5-√23
Answer:
24
Step-by-step explanation:
Add 7 to both sides
c/3=8
Multiply both sides by 3
c=24
hope this helped

Answer:
the easiest to solve for is x in the first equation
Answer:
Correct option:
Is a measure of the amount of variability in one variable that is shared by the other.
Step-by-step explanation:
<em>R</em>-squared is a statistical quantity that measures, just how near the values are to the fitted regression line. It is also known as the coefficient of determination.
The coefficient of determination <em>R</em>² specifies the percentage of the variance in the dependent-variable (<em>Y</em>) that is forecasted or explained by linear regression and the forecaster variable (<em>X</em>, also recognized as the independent variable).
The coefficient of determination <em>R</em>² can be computed by the formula,
Or,
Here,
MSS = model/regression sum of squares
TSS = total sum of squares
Thus, the correct option is:
" Is a measure of the amount of variability in one variable that is shared by the other."
