There are 1,375 students in one elementary school if all elementary schools have the same number of students how many students are in seven schools

9,625 students

Step-by-step explanation:

If all students have the same number of students the will all have 1,375 students according to the question. Therefore; Seven different schools will each have 1,375 students each. Mathematically we can write this as:

y = 1,375s (if s means amount of schools)

Since there are seven schools y = 1,375(7)

This simplifies to y = 9,625 meaning that there are 9,625 total students.

92358 students would be in the joe school

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
