Answer:
.
Step-by-step explanation:
It is given that the sum of 10 and one-third of a number is 25.
Let as consider n be the unknown number.
One-third of a number 
Sum of 10 and one-third of a number 
The sum of 10 and one-third of a number is 25. It can be written as
Therefore, the required equation is .
F^-1= positive or negative x square root
y=1/3x-1
We know straight away that the y intercept is -1 from the equation.
y-intercept: (0,-1)
To find the x intercept plug in 0 for y in the equation.
y=1/3x-1
0=1/3x-1
1/3x=1
x=3
x-intercept: (3,0)
answers: y-intercept: (0,-1) and x-intercept: (3,0)
Answer:
B. Variance = r2 = 0.7225
Step-by-step explanation:
Given the correlation coefficient, variance is obtained by squaring the correlation coefficient to obtain what is also know as coefficient of determination. Gives information on the predictive power of the model
Im confused could you explain what the questions are better.
