What is the range of a function f(x)=-x+15 when the domain is {-3,-1,11}?
hodyreva [135]

Answer:

The range is the output value or the y value.

You would work backwards to find the domain.

f(x) = 4x - 1                              f(x) = 4x - 1

3 = 4x - 1                                    7 = 4x - 1

add 1 to both sides                    add 1 to both sides

4 = 4x                                            8 = 4x

divide both sides by 4              divide both sides by 4

x = 1                                              x = 2

f(x) = 4x - 1                                  f(x) = 4x - 1

11 = 4x - 1                                      15 = 4x - 1

add 1 to both sides                      add 1 to both sides

12 = 4x                                              16 = 4x

divide both sides by 4                  divide both sides by 4

x = 3                                                    x = 4

Domain { 1, 2, 3, 4}

50 question true-false final exam (two-points each question) and you never paid attention in the class (or knew anything about t
DanielleElmas [232]

Title:

<h2>Check the explanation.</h2>

Step-by-step explanation:

As all the questions of the exam carry 2 points, at least \frac{56}{2} = 28 questions need to be correct to get 56 marks.

In order to get a maximum of 56 marks, at most 28 answers needs to be correct.

Every question has two option. Hence, the probability of getting a particular question right is \frac{1}{2}.

The probability that exactly n questions will be right is ^{50}C_n (\frac{1}{2} )^n (\frac{1}{2} )^{50 - n} = ^{50}C_n (\frac{1}{2} )^{50}.

The probability that at most 28 questions will be right is ∑^{50}C_n (\frac{1}{2} )^{50}, 0\leq n\leq 28.

Similarly, the probability that at least 30 questions will be right is ∑^{50}C_n (\frac{1}{2} )^{50}, 30\leq n \leq 50.
