In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Joseph 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. 103 visitors purchased no costume. 161 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 more than one costume as a decimal to the nearest hundredth.

Answers

The probability that the next person will purchase more than one costume is 0.03

How to solve for the probability

We have the following details to solve the problem with

The people that did not purchase any costume = 103

Those that purchased exactly one costume = 161

Those that purchased more than one costume = 7

The total number of persons that we have here would be

103 + 161 + 7

= 271

We are to find the probability that the next would purchase more than 1 costume.

This is given as:

7 / 271 = 0.0258

To the nearest hundredth = 0.03

Hence, 0.03 is the probability that the next person is going to buy more than one costume.

If the value of a in the quadratic function f(x) = ax² + bx + c is 1/2, the function will: C. open up and have a minimum.

What is the general form of a quadratic function?

In Mathematics and Geometry, the general form of a quadratic function can be modeled and represented by using the following quadratic equation;

y = ax² + bx + c

Where:

a and b represents the coefficients of the first and second term in the quadratic function.c represents the constant term.

Since the leading coefficient (value of a) in the given quadratic function f(x) = ax² + bx + c is positive 1/2, we can logically deduce that the parabola would open upward. Also, the value of the quadratic function f(x) would be minimum.

What are the zeros of this function (g)(x)=3x^2-33x-180

Answers

Answer:

3x²-33x-180=3(x²-11x-60)=3(x-15)(x+4)

The roots are x-15=0, x=15 and x+4=0, x=-4

3x² - 33x - 180 = 0

3(x² - 11x - 60) = 0

3(x - 15)(x + 4) = 0
(x - 15)(x + 4) = 0

x - 15 = 0 or x + 4 = 0
