x=30º

∠CAB=60°

∠ACB=80°

Step-by-step explanation:

Because the angles of every triangle add up to 180º, we know that:

[tex]2x+20+2x=180-40\\ 4x=180-40-20\\ 4x=180-60\\ 4x=120\\ x=\frac{120}{4}[/tex]

x=30º

Plug that in for x on both angles, and you will get

∠CAB=60°

∠ACB=80°

Which value can fill in the blank in the function f(x) = ____|x| to make its graph wider than that of the parent function, f(x) = |x|?

–1

4

Answers

Answer:

_4

Step-by-step explanation:

I took the quiz in the car 100

If we want to make the graph wider, then we must have a horizontal dilation, so the correct option will be 1/4.

How do horizontal dilations work?

A horizontal dilation is a transformation that makes the graph of a function wider.

For a function f(x) an horizontal dilation of scale factor k (with k > 1) is written as:

g(x) = f(x/k)

For the case of the absolute value function we will have:

g(x) = |x/k| = (1/k)*|x|

So we need to find the value (1/k).

Remenber that k > 1, then 0 < (1/k) < 1.

This means that the only values between 0 and 1 could fill the blank in such a way that the graph of that function is wider than the one of the parent function, so from the given options, we will take:

1/k = 1/4

Then the function is:

g(x) = (1/4)*|x|

This function will have a graph wider than the one of f(x) = |x|

Step-by-step explanation:

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Fwam sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 417 visitors purchased no costume. 63 visitors purchased exactly one costume. 7 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase no costume as a decimal to the nearest hundredth.

Answers

Answer:

0.86

Step-by-step explanation:

The probability that the next person will purchase no costume is 36%.

What is probability ?

To express the probability that the next person will purchase no costume as a percent to the nearest whole number, we will use the total number of visitors to the website as the denominator and the number of visitors who purchased no costume as the numerator.

The total number of visitors to the website,

168 + 252 + 47 = 467

The number of visitors who purchased no costume = 168.

So, the probability that the next person will purchase no costume is:

168/467 = 0.360

0.3609 × 100

= 36.09

Rounding this to the nearest whole number, we get,

36%
