A discrete variable is a type of variable which contains a finite number of values. It usually takes its values from the set of whole numbers.

From the random variable described, the random variable that is descrete is "You measure the maximum heart rate in beats per minute".

This is because, heart rate cannot be partitioned it only takes counting number values. You either have 1 beat per minutes, 2 or 3 and so on beats per minute. But you cannot have 2.5 or 3.8 and so on beats per minute.
So heart rate cannot take decimal or fractional values and hence, it is a discrete random variable.

What is the surface area of a sphere with a diameter of 12 centimeters ?

nasty-shy [4]

Answer:

$A=452.39\ cm^2$

Step-by-step explanation:

The formula to calculate the surface area of a sphere is the following:

$A=4\pi r^2$

Where A is the area of the sphere and r is the radius of the sphere.

In this case we know that the diameter d of the sphere is:

$d = 12\ cm$

The diameter is:

$d = 2r$ .

Thus

$r = \frac{d}{2}\\\\r = \frac{12}{2}\\\\r=6\ cm$

Then the surface area of the sphere is:

$A=4\pi (6)^2\\\\A = 144\pi\ cm^2\\\\A=452.39\ cm^2$

H(x)=x-12/4 inverse function with steps please

OleMash [197]

Answer: x = H(x) + 3

Step-by-step explanation: The inverse function is x expressed with H(x). There aren't always inverse functions but in this case you just put the fraction from the right hand side to the left hand side. After the divison you get what I wrote.

Use the parabola tool to graph the quadratic function.

Masja [62]

Answer:

f(x) = 2x² + 4x - 16

= 2(x² + 2x) - 16

= 2(x² + 2(x)(1) + 1² - 1²) - 16

= 2(x + 1)² - 2 - 16

= 2(x + 1)² - 18

Vertex: (-1, -18) minimum

Second point can be the y-intercept:
