3 is real 4th roots of 81
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.

Answer: C = - 71/3 or -23.6 or -23 2/3 All the same
Step-by-step explanation:
- Hypotenuse= ML
- Perpendicular=KL=15
- Base= KM=8
By using Pythagoras theorem.
- h²=p²+b²
- ML²=15²+8²
- ML²=225+64
- ML=√289
Therefore ML= 17...
