How does the scatter plot of a nonlinear association differ from that of a linear association?

Answers

Scatter Plots of a non-linear association represent points scattered all over the graphs as there is no association with them. On the other hand, a linear association represents dots placed in a more straight line that covers most of the dots on a graph. To sum it up, a nonlinear association is a bunch of random dots all over the place and a linear association is straight with no mess-ups (nothing).

A sign in a bakery gives these options:

15 cupcakes for $26
24 cupcakes for $42
40 cupcakes for $66
Find each unit price to the nearest cent, and show your reasoning.
Which option gives the lowest unit price?

Answers

Answer:

The lowest unit price would be last option

Step-by-step explanation:

We must divide the price by the amount of cupcakes we will be getting. Once we do that we'll get:

A. 1.77 cents

B. 1.75 cents

C. 1.65 cents

Hope this helped

Answer:

40 cupcakes for $66

Step-by-step explanation:

To find the unit price of something, dived the total amount by how may there are.

$26 divided by 15 cupcakes would be $1.7333333333, but if you round it up, it would be  $1.74

$42 divided by 24 cupcakes would be $1.75

$66 divided by 40 cupcakes would be $1.65
