Marty is explaining to susan how to solve the following problem, -4 – (-5)
he told susan that to subtract an integer, add its opposite. which of following would be correct?
a. to subtract an integer, add its opposite; 4 + (-5) = -1.
b. to subtract an integer, add its opposite; 4 + 5 = 9.
c. to subtract an integer, add its opposite; -4 + (-5) = -9
d. to subtract an integer, add its opposite; -4 + 5 = 1

The correct answer is:

To subtract an integer, add its opposite; -4 + 5 = 1

Step-by-step explanation:

Marty is explaining to Susan how to solve the following problem, -4 – (-5)  

He told Susan that to subtract an integer, add its opposite.

We know that whenever we solve the two terms, first we multiply the signs.

It means that the negative sign outside the round bracket will be multiplied with the negative sign of -5

That is,

-4 - (-5)

By multiplying the signs we get the terms:

-4 + 5

=1

Thus the correct option is D

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

yes   because as the functions are graphed they eventually will intersect unless otherwise
