The colony of penguins travel 3/5 of a kilometer a day. how many kilometers will they travel in a week.

4 1/5

Step-by-step explanation:

(2*3 is the same as 2x3 in multiplication)

Since in a week there are 7 days, you multiply the number of days to the distance walked per day. Which is 7*(3/5), or (3/5)*7

So (3/5)*7=4 1/5 or 4.2

(3/5)*7 equals

(3/5)+(3/5)+(3/5)+(3/5)+(3/5)+(3/5)+(3/5)=(21/5)

There are four 5's in 21, so it is 4 wholes.

4 an the remaining 1 over 5

=4 1/5

step-by-step explanation:

85.560%

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
