Answer:

0.06 = 6% probability of landing open side up.

0.14 = 14% probability of landing closed side up.

0.8 = 80% probability of landing on its side.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes. For an experimental probability, these numbers are taken from previous trials.

Landing open side up:

3 out of 50, so:

p = \frac{3}{50} = 0.06

0.06 = 6% probability of landing open side up.

Landing closed side up:

7 out of 50, so:

p = \frac{7}{50} = 0.14

0.14 = 14% probability of landing closed side up.

Landing on its side:

40 out of 50, so:

p = \frac{40}{50} = 0.8

0.8 = 80% probability of landing on its side.

Given f(x) = x² - 10x + 22, what is the range of f?
adoni [48]

Answer:

[-3, ∞)

Step-by-step explanation:

There are many ways to find the range but I will use the method I find the easiest.

First, find the derivative of the function.

f(x) = x² - 10x + 22

f'(x) = 2x - 10

Once you find the derivative, set the derivative equal to 0.

2x - 10 = 0

Solve for x.

2x = 10

x = 5

Great, you have the x value but we need the y value. To find it, plug the x value of 5 back into the original equation.

f(x) = x² - 10x + 22

f(5) = 5² - 10(5) + 22

      = 25 - 50 +22

      = -3

Since the function is that of a parabola, the value of x is the vertex and the y values continue going up to ∞.

This means the range is : [-3, ∞)

Another easy way is just graphing the function and then looking at the range. (I attached a graph of the function below).

Hope this helped!
