Yep :) You're right!

The total probability of anything is always 100%, obviously.

If there are 4 choices, and you're equally likely to select either one, you can do 100% / 4 choices = 25%.

One of them have to be correct, so 1 of the 4 are bound to be right. 1/4 is also the same as 25%, hence you're correct! :)

The polygons below are similar. Find the scale factor of the SMALLER figure to the LARGER.
abruzzese [7]

Answer:

A. 5:6

Step-by-step explanation:

The scale factor of the smaller figure to the larger = the ratio of a side of the smaller figure to the corresponding side of the larger figure.

Thus, side length of 25 units of the smaller figure corresponds to the side length of 30 units.

Therefore:

Scale factor = 25:30

Simplify

Scale factor of the smaller figure to the larger = 5:6

Do the following lengths satisfy the Pythagorean Theorem? Lengths =14, 50, 48.<br> Yes<br> No
seraphim [82]

Answer:

  yes

Step-by-step explanation:

  14² +48² = 196 +2304 = 2500 = 50²

The three lengths (14, 48, 50) are a Pythagorean triple.

__

<em>Additional comment</em>

The two smaller numbers correspond to side lengths. The larger one corresponds to the hypotenuse length.

We typically write the numbers of a Pythagorean triple in increasing order, but the order doesn't really matter. As sides of a triangle, the triangle formed is a right triangle, regardless of the order.

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!
