Y=11 is a function, because a function is a set of numbers where for you only have one input for every output. In this case it is a one kt one function because there is only one output for every input. Every input results in 11, therefore this is a function.

If the solutions to a polynomial equation are -5, 0, and 1, which of the following could be the expanded form of the polynomial
AVprozaik [17]

Answer:

The polynomial would be f(x) = x^3 + 4x^2 - 5x

Step-by-step explanation:

In order to find this, start with the equations that x is equal to each of the solutions. Then solve each of those expressions for 0.

-5 = x

0 = x + 5

1 = x

0 = x - 1

0 = x

Now put each of the terms that you have in parenthesis and multiply them all together.

f(x) = (x)(x + 5)(x - 1)

f(x) = (x)(x^2 + 4x - 5)

f(x) = x^3 + 4x^2 - 5x

3. What are the identification numbers for ten students chosen at random from a population of 78 students based on the following
Naya [18.7K]

Answer:

27 67 16 01 27 35 21 37 74 10

Step-by-step explanation:

Starting from the left, you pick two numbers together and skip two numbers if it is greater than 78.

Meaning:

27816 78416 01822 73521 37741 016312 68000 53645 56644 97892 63408 77919 44575

You pick [27] and leave 81 since it is greater than 78, the population number.

Then you pick [67] and leave 84 as it is also greater than 78.

Then you pick [16] and [01] but leave 82, as it is greater than 78.

Then pick [27], [35], [21], [37], [74] and [10] since they are all less than 78.

At this juncture, you have identified 10 numbers: 27 67 16 01 27 35 21 37 74 10

Effectus [21]

Answer:

4/20 x 3/19 = 3/95

Step-by-step explanation:

The chance for the first marble is 4/20 (1/5), multiplied by the second event, which probability is 3/19 (with removal), becomes 3/95  (fundamental counting principle).
