The line that is a linear model from the data is line c.
The 2 graphs on the left are exponential
The other 2 are linear
Set up a ratio comparing the sample portion to the whole portion.
x= # of all dogs likely to have chip
Sample: 8 out of 50
Whole: x out of 2,300
8/50= x/2300
cross multiply
(50*x)= (8*2300)
50x= 18400
divide both sides by 50
x= 368
ANSWER: 368 dogs in Clarkson are likely to have a microchip.
Hope this helps! :)
I’m pretty sure it’s true
