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:
I don't understand what you mean by 300 and 70, unless you meant 300/70 (in that case it would be 30/7).
5/10 would be 1/5
8/100 would be 2/25.
Okay, let's do this~
we want v isolated on one side so let's bring w over through subtraction
now we have 5/9v=z-w
now, to get rid of that fraction attached to v, we will multiply it's reciprocal on both sides.
*the reciprocal of 5/9 is 9/5
(5/9) x (9/5) cancel each other leaving v isolated to the left
the other side should look like this 9/5(z-w)
now we put both parts together to end up with:
v= 9/5(z-w)
there you go! :D
Answer:
$225 = $15 a + $ 10 c
Step-by-step explanation:
Given,
Total price = $225
Cost of concert ticket for adults= $15
Cost of concert ticket for children = $10
System of equation to represent scenario
a is variable for adult
c is variable for children
Now,
Total price = $15 a + $ 10 c
$225 = $15 a + $ 10 c
