Answer:
Value of n is 52
Step-by-step explanation:
So you have equation: 6.2n – 3.7n = 85 + 45
First, you need to collect the like terms and add the numbers on the other side: 2.5n=130
Now, you need to divide both sides of equation by 2.5. And you will get the answer. n=52
Answer:
Total cost of CD player = $58.52
Step-by-step explanation:
Given data:
Price of CD player on sale= $54.95
Local sales tax = 6.5%
Total cost of CD player = ?
Solution:
Local sales tax= (6.5 * 54.95)/100 = $3.57
Total cost of CD player = Price of CD player on sale + Local sales tax
= $54.95 + $3.57
Total cost of CD player = $58.52
Isosceles and a right triangle
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!
