The density of a fish tank is 0.2 fish over feet cubed. there are 8 fish in the tank. what is the volume of the tank? a. 4ft cubed b. 16ft cubed c. 32 ft cubed or d. 40 ft cubed

Option d

Step-by-step explanation:

We are given that the density of fish tank =0.2 fish over feet cubed

We have to find the volume of fish  tank

To find the volume of fish tank we are using density formula

Total number of fish =8

Substitute the value the we get

0.2=

By cross multilply we get

0.2 V=8

Using division property of equality then we get

V=  feet cubed

Hence, option d is true.

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
