Which of the following phrases can be written as the algebraic expression 9(86−x)?

Possible Answers:
Nine mutiplied by the difference of eighty-six and a number

The product of nine and a number subtracted from eighty-six

Eighty-six subtracted from the product of nine and a number

The correct answer is not given among the other responses.

Nine mutiplied by the difference of a number and eighty-six

First option: Nine mutiplied by the difference of eighty-six and a number.

Step-by-step explanation:

We have the expression:

9(86−x)

We have a difference of number in parenthesis, meaning that this operation will happen first, and then its result will be multiplied by 9

So, we know that this expression means that 9 will be multiplied by something, and this something is a difference of 86 and a number (86 first, and the other number second).

Then, the correct answer would be:

Nine mutiplied by the difference of eighty-six and a number.

First option is the correct one.

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

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
