Answer: x = 63
Step-by-step explanation:
15/3 = 5
3 * 21 = 63
63/15 = 21/5
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! :)
Ok so if it has roots of -3 and 5 it should be divisible by (x+3) and (x-5) and it is also divisible by 2
Therefore it is divisible by 2(x+3)(x-5)
If you multiply that out you get 2x^2 -2x -15
