Three letters are chosen at random from the letters P, A, N, S, O, L. What is the size of the sample space of this experiment? Assume that the order of the letters matters. That is, PAN is different from APN.A.24
B.60
C.120
D.210
E.336

Answers

Answer 1
Answer: 6 ways you can arrange 3 letters, and there's 20 different sets of 3 you can chose from 6 so 6 * 20 = 120
Answer 2
Answer: i dont get this question can you please give more information

Alissa is analyzing an exponential growth function that has been reflected across the y-axis. She states that the domain of the reflected function will change because the input values will be the opposite sign from the reflected function. Simon disagrees with Alissa. He states that if an exponential function is reflected across the y-axis, the domain will still be all real numbers.

Answers

Answer:

Consider the exponential function

y=Ae^x

                     -----------(1)

and when it is reflected across y axis , it's equation becomes

y=Ae^(-x)

                --------------------------(2)

As, domain of a function is defined as the set of all values of x , for which y is defined.

So, for function 1,  domain is set of all real numbers.That is , x∈[-∞ ,∞]

And for function 2, which is reflection of function 1, it's domain will also be set of all real numbers.That is , x ∈ [-∞, ∞]

So, Simon is correct between Alissa and himself, as he is saying if an exponential function is reflected across the y-axis, the domain will still be all real numbers is true statement.
Simon is correct because even though the input values are opposite in the reflected function, any real number can be an input.

A box contains five red marbles, seven white marbles, and four green marbles. A student is computing probabilities by drawing marbles out of the box. Drawing one marble, what is the probability that it is red?

Answers

Answer:

Step-by-step explanation:

you have a total of 5+7+4=16 marbles in the box.

5 are red

7 are white

4 are green

If you randomly select 1 marble out of the box, the probabilities are:

5/16 chance of being red

7/16 chance of being white

4/16 chance of being green

Evaluate. f(x) = 2x - 1, f(2)

Answers

Answer:

f(2) = 3

Step-by-step explanation:

Substitute 2 for x, and evaluate the expression.

f(x) = 2x - 1

f(2) = 2(2) - 1

f(2) = 4 - 1

f(2) = 3
answer: so, f(x)=2(2)-1
which will be =3 so answer is 3
