Answer:
Solution-
We know that,
Residual value = Given value - Predicted value
The table for residual values is shown below,
Plotting a graph, by taking the residual values on ordinate and values of given x on abscissa, a random pattern is obtained where the points are evenly distributed about x-axis.
We know that,
If the points in a residual plot are randomly dispersed around the horizontal or x-axis, a linear regression model is appropriate for the data. Otherwise, a non-linear model is more appropriate.
As, in this case the points are distributed randomly around x-axis, so the residual plot show that the line of regression is best fit for the data set.
Hope this helps!

Step-by-step explanation:
we know that
To find what fraction of the remaining pieces are apple, divide the remaining pieces of apple by the total remaining pieces
we have that
the remaining pieces of apple is equal to 6
the total remaining pieces is 11
so
Answer:
3^x=9^{x+5}
Step-by-step explanation:
3^x=9^{x+5}
x^2-x-6=0
x^4-5x^2+4=0
\sqrt{x-1}-x=-7
\left|3x+1\right|=4
\log _2\left(x+1\right)=\log _3\left(27\right)
3^x=9^{x+5}
If request to solve;
\mathrm{Convert\:}9^{x+5}\mathrm{\:to\:base\:}3
9^{x+5}=\left(3^2\right)^{x+5}
\mathrm{Solve\:}\:x=2\left(x+5\right):\quad x=-10
Answer:
Yes exactly...
Step-by-step explanation:
Yes you can. If a vertical line passes trough a line more than once in a graph, then it is inverse but if it passes trough only once it is a function
