And irrational number is a number than cannot be written as a simple fraction.

Two good examples of irrational numbers are PI and the square root of 2. These numbers have never-ending decimals, and their decimals never repeat.

Answer:

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

Which ordered pairs represent points on the graph of f(x)= Negative RootIndex 3 StartRoot x EndRoot? Check all that apply.

DedPeter [7]

Answer:

(0, 0)
(1, –1)
(8, –2)

Step-by-step explanation:

We normally think of the ordered pairs as ...

(x, y) = (x, -∛x)

Another way to think about them is ...

(x, y) = (-y³, y)

I find it a little easier to think about the cube of a number, rather than its cube root.

For the y-values given, -2, -1, 0, 2, the points that will be on the graph are ...

(8, -2), (1, -1), (0, 0), (-8, 2)

The first three of these points are listed in your answer choices.

Find the volume of the sphere. <br> Either enter an exact answer in terms π or use 3.14 for π

Lunna [17]

The equation for volume of a sphere is (4/3)(pi)(r)^3. So you would plug in he radius 9 into the equation. It would simplify to equal (4/3)(pi)(729). It simplifies further to equal (972)(pi)

Can someone explain to me?

san4es73 [151]

The answer is (it can be curved) because it's doesn't have to cross the origin and it's a U shape so it can't look like a straight line and it doesn't have a constant rate of change. :)

A binomial distribution has p = 0.05 and n = 50. what is the mean of this distribution?

Kruka [31]

2.5 is the mean of this distribution.

What is the distribution's mean?

The expected value, commonly known as the mean of a statistical distribution with a continuous random variable, is calculated by integrating the product of the variable's probability as described by the distribution.
The lowercase Greek letter mu () stands for the expected value. A probability of 50% equals zero standard deviations, and the mean is in the middle of the normal distribution.

Given: p = 0.05 and n= 50

Mean of the binomial distribution = n×p = 50 × 0.05 = 2.5

Therefore, option a is the correct answer. Other options are incorrect because these are irrelevant.
