Answer:

The range of the function is all real numbers less than or equal to 9.

Step-by-step explanation:

Given : The function f(x) = –x2 – 4x + 5 is shown on the graph.

To find : Which statement about the function is true.

Solution : We have given that f(x) = –x² – 4x + 5 .

Domain : domain are the set of input values on which the function is defined or real.

F(x) is not undefined for any value.

Then , (-∞ , ∞)

Range : range is the set of values dependents variable on which function is defined.(-∞ ,0]

Therefore, The range of the function is all real numbers less than or equal to 9.

The newest invention of the 6.431x staff is a three-sided die. On any roll of this die, the result is 1 with probability 1/2, 2

Gwar [14]

Answer:

<h2>The answer is 0.23(approx).</h2>

Step-by-step explanation:

The given die is a three sided die, hence, there are only three possibilities of getting the outcomes.

We need to find the probability of getting exactly 3s as the result.

From the sequence of 6 independent rolls, 2 rolls can be chosen in $^6C_2 = \frac{6!}{2!\times4!} = \frac{30}{2} = 15$ ways.

The probability of getting two 3 as outcome is $\frac{1}{4} \times\frac{1}{4} = \frac{1}{16}$ .

In the rest of the 4 sequences, will not be any 3 as outcome.

Probability of not getting a outcome rather than 3 is $1 - \frac{1}{4} = \frac{3}{4}$ .

Hence, the required probability is $15\times\frac{1}{16}(\frac{3}{4})^4 = \frac{1215}{4096}$ ≅0.2966 or, 0.23.
