In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Huds

on 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.
224 visitors purchased no costume.
103 visitors purchased exactly one costume.
32 visitors purchased more than one costume.

Based on these results, express the probability that the next person will purchase no costume as a percent to the nearest whole number.

Answer:

62%

Step-by-step explanation:

Given the information :

224 visitors purchased no costume.

103 visitors purchased exactly one costume.

32 visitors purchased more than one costume.

Based on these results, express the probability that the next person will purchase no costume as a percent to the nearest whole number.

Probability that next person will purchase no custome:

Probability = no of successes / total number of trials

Total number of trials :

(purchase no custome + purchase exactly one + purchase more than one)

= (224 + 103 + 32) = 359

Hence, Probability that next person will purchase no custome:

= 224 / 359

As a percentage :

(224 / 359) * 100%

= 0.6239554 * 100%

= 62.39 %

= 62% ( nearest whole percent)

On a number line the directed line segment from Q to S has endpoints Q at -14 and S at 2. Point R partitions the directed line s
liq [111]

Answer:

Step-by-step explanation:

The distance from Q to S is 2 - (-14), or 16.

We start at point Q.  Note how 3 and 5 add  up to 8, which allows us to write:

R = Q + (3/8)(16), or R = -14 + 6, or R = -8.

From R to S it is (5/8)(16), or 10 units.

The directed line segment is partitioned into segments of lengths 6 and 10, whose combined length is 16, as expected.

HELP! (Urgent pre-calculus question.)
marishachu [46]
2. means that for every x, there is eactly one y
basically, we can use the vertical line test to see if it crosses at any 2 points

first one works
2nd one works
3rd works
4th works
5th works
they are all one to one functions



3.
easy
steps
for f(x)=?
replace f(x) with y
switch x and y
solve for y
replace y with  f⁻¹(x)
so

f(x)=(1+x)^3-2
replace
y=(1+x)^3-2
switch
x=(1+y)^3-2
solve
x+2=(1+y)^3
\sqrt[3]{x+2}=1+y
-1+\sqrt[3]{x+2}=
replace
f^{-1}(x)=-1+\sqrt[3]{x+2}
first option



4.
domain, hmm we can't divide by 0 so domain is all real numbers except for x=0
domain is (-\infty,0) \cup(0,\infty)
hmm, range
as x approaches negative or positive infinity, f(x)=5
as x approaches 0 from the left, f(x) appraoches negative infintiy
as x approaches 0 from the right , f(x) appraoches positive infintiy
so range is (-\infty,5) \cup(5,\infty)

domain is (-\infty,0) \cup(0,\infty)
range is (-\infty,5) \cup(5,\infty)
answer is the 4th option

The mean of a set of data is 3.77 and its standard deviation is 3.39. Find the z score for a value of 6.19
melomori [17]
Z = (x - mu)/sigma
z = (6.19 - 3.77)/3.39
z = 0.71386430678467
z = 0.71

The approximate z score, rounded to two decimal places, is 0.71
