3b - c +5 if c= - 4, b=2.

Mathematics
1 answer:
AnnZ [28]2 years ago
3 0

Answer:

15

Step-by-step explanation:

To find the answer, plug the values of each variable into the equation and simplify. It may be easiest to plug one variable in at a time, simplify, then plug the next variable in. Remember, if the equation is asking you to subtract a negative number, the negatives cancel and you want to add the numbers.

b = 2          c = -4

3b - c + 5                                      <----- Original expression

3(2) - c + 5                                    <----- Plug 2 in for "b"

6 - c + 5                                        <----- Multiply 3 and 2

11 - c                                              <----- Add 6 and 5

11 - (-4)                                           <----- Plug -4 in for "c"

15                                                  <----- Add 11 and 4

Sati [7]

Answer: the percent of the students at this university are foreign = 30%

Step-by-step explanation:

Given: Probability that college students are foreign students who also smoke: P(S|F)=0.12

Probability that foreign college students smoke P(S∩F)=0.4

The probability that the students at this university are foreign :

P(F)=\dfrac{P(S\cap F)}{P(S|F)}  [By conditional probability formula]

=\dfrac{0.12}{0.4}\\\\=0.3

Hence, the percent of the students at this university are foreign = 30%
