Answer:
the number of chips in the bag is 40
Step-by-step explanation:
On a game show, a contestant randomly chooses a chip from a bag that contains numbers and strikes. The theoretical probability of choosing a strike is 1/5.
Let x be the number of chips in the bag
the bag contains 8 strikes
the probability of choosing a strike from 8 strikes is 8/x
given probability of choosing a strike is 1/5
cross multiply it
x= 40
So, the number of chips in the bag is 40

use midpoint equation
radius = distance between midpoint and one of the endpoints.
midpoint: (3+5)/2, (2+6)/2, (5+7)/2 = (4,4,6)
equation of sphere: (x-4)^2 + (y-4)^2 + (z-6)^2 = r^2
square distance between midpoint and one of the endpoints.
r^2 = 6
Equation: (x-4)^2 + (y-4)^2 + (z-6)^2 = 6
