Write a single algebraic expression for the following sequence of operations. Begin with a number represented by n. Multiply by -2 add 5 to the previous expression divide the previous expression by 3 subtract 6 from the previous expression multiply the previous expression by 4 add 7 to the previous expression

-2n-15 1/3

Step-by-step explanation:

-2n+5/3-6(4)+7

-2n+5/3-24+7

-2n+1 2/3-17

-2n-15 1/3

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
