Answer:
n = 6[tex]\sqrt{3}[/tex]
Step-by-step explanation:
you can create this proportion:
18/n = n/6
cross-multiply:
n² = 108
n = [tex]\sqrt{108}[/tex]
[tex]\sqrt{108}[/tex] = [tex]\sqrt{4}[/tex]·[tex]\sqrt{9}[/tex]·[tex]\sqrt{3}[/tex] = 2·3·[tex]\sqrt{3}[/tex] or 6[tex]\sqrt{3}[/tex]

Jovan spent 2/3 of his savings on a watch. He also spent of 1/5 his savings on a bag. (a) What fraction of his savings was left? (b) How much did he spend on both the items? Tell me the steps to get the answer please, Thanks... Have A Good Day/ Night.. :D
Answer:
2/15
13/15
Step-by-step explanation:
Amount spent = sum of amount spent on watch and bag
[tex]\frac{2}{3} + \frac{1}{5}[/tex]
[tex]\frac{10 + 3}{15}[/tex]
= [tex]\frac{13}{15}[/tex]
Fraction left = 1 - amount spent
1 - 13/15

Circles A, B, and C overlap. The overlap of circles B and C is labeled x.
Which statements are true about x? Select three options.
x ∈ B ⋃ C
x ∈ B ∩ C
x ∈ A ⋃ C
x ∈ A ∩ C
x ∈ A
Given:
Circles A, B, and C overlap.
The overlap of circles B and C is labeled x.
To find:
The three correct statements about x.
Solution:
It is given that the overlap of circles B and C is labeled x. It means x represent the common elements of B and C.
So, x belongs to the intersection and union of B and C.
[tex]x\in B\cup C[/tex]
[tex]x\in B\cap C[/tex]
Since x is the element of C, therefore it is also the element of A union C.
[tex]x\in A\cup C[/tex]
The overlap of circles B and C is labeled x. It means [tex]x\notin A[/tex]. So,
[tex]x\notin A\cap C[/tex].
Therefore, the correct options are A, B and C.
Answer:
A, B and C.

A salesman who is on the road visiting clients thinks that, on average, he drives the same distance each day of the week. He keeps track of his mileage for several weeks and discovers that he averages 122 miles on Mon- days, 203 miles on Tuesdays, 176 miles on Wednesdays, 181 miles on Thursdays, and 108 miles on Fridays. He wonders if this evidence contradicts his belief in a uni- form distribution of miles across the days of the week. Explain why it is not appropriate to test his hypothesis using the chi-square goodness-of-fit test.
Answer:
The conditions are not met.
Step-by-step explanation:
The conditions for the chi square test for goodness of fit are
1) the sample is a random sample
2) the variable under study is categorical
3) all expected value of the number of sample observations are greater or equal to 5.
A)The observations must be independent
B) for 2 categories the expected values must be at least 5
C) for the 3 categories the expected values must be at least 1 and no more than 20% may be smaller than 5
The observations given may not be independent i.e have equal chances of occurrences or are maybe dependent on each other in the sense that there maybe a limit for his traveling mileage or the a limit for petrol ( fuel ) usage . So if he is required to drive 500 miles in a week each day mileage depends on the other day mileage .
Also we are given the information that keeps track of his mileage for several weeks, but we are not sure if several refers to more than 5 .
As both conditions are not clearly satisfied it is not appropriate to test his hypothesis using the chi-square goodness-of-fit test.
The sample must also be a random sample.
Here he has taken the mean of all the days.

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Boubacar 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.
120 visitors purchased no costume.
235 visitors purchased exactly one costume.
3 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.

Suppose that an individual has a body fat percentage of 13.6% and weighs 189 pounds. How many pounds of his weight is made up of fat? Round your answer to the nearest tenth.
HELPPPPPP!!!!!!!!!!
Answer:
25.7 lbs
Step-by-step explanation:
189/100=1.89
1.89*13.6=25.704
25.7 lbs
Answer:
25.7
Step-by-step explanation:
You need to do 13.6 percent of 189 which is 25.704 without rounding
Round that to the nearest tenth and you have 25.7

Answer:
In the first one answer is r²
In second one answer is 3
Step-by-step explanation:
Yes it is Algebra with different powers
In first one (6r4+4r) +(__- 2r4 + 3r) = 4r4 + r2 + 7r
Like terms are added:
6r^4- 2r^4 + 4r + 3r +____ = 4r^4 + r2+ 7r
4r^4+7r +___ = 4r^4 + r^2 + 7r
Therefore ___ = r^2
In second one:
(__ -8x - x^2)-(4x^2 -7 +6x) = -5x^2 +14x +10
Open the brackets
__ -8x - x^2-4x^2 +7 -6x = -5x^2 +14x +10
Add like terms
__ -14x -5x^2 + 7= -5x^2 +14x +10
Therefore
___ + 7 = 10
___ = 10 -7 = 3

Diego predicts that his basketball team has a 23 probability of winning each of their next 7 games. Select two ways Diego could accurately simulate the number of games his team will win.
Answer:
(c) and (e)
Step-by-step explanation:
Given
[tex]Pr = \frac{2}{3}[/tex]
Required
Which 2 options can be used to simulate the given probability.
The two options are (c) and (e)
The proof is as follows;
Option (c)
We have:
[tex]Rolls = 7[/tex]
A cube has 6 faces. So:
[tex]S = \{1,2,3,4,5,6\}[/tex]
[tex]n(S)=6[/tex]
The probability of getting ones, twos, threes, and fours is:
[tex]Pr = \frac{n(1,2,3,4)}{n(S)}[/tex]
In: [tex]S = \{1,2,3,4,5,6\}[/tex]
[tex]n(1,2,3,4) = 4[/tex]
So:
[tex]Pr = \frac{4}{6}[/tex]
Simplify
[tex]Pr = \frac{2}{3}[/tex]
Option (e)
We have:
[tex]White = 10[/tex]
[tex]Red = 5[/tex]
[tex]Count = 7[/tex]
Record the probability of white.
This is calculated as:
[tex]Pr = \frac{White}{Total}[/tex]
[tex]Pr = \frac{White}{White + Red}[/tex]
[tex]Pr = \frac{10}{10+5}[/tex]
[tex]Pr = \frac{10}{15}[/tex]
Simplify
[tex]Pr = \frac{2}{3}[/tex]

Mila and samuel had an equal amount of money for shopping. Mila spent $42 and Samuel spent $36. After that, Mila had 1/2 of what Samuel has left. How much money Milla had initially?
Answer:
Mila had $48 initially
Step-by-step explanation:
Let the amount of money they had be x
Mila spent $42; what is left would be x-42
Samuel spent $36: what is left would be x-36
So, what Mila had left is half of what Samuel has; that would be;
x-42 = 1/2(x-36)
2(x-42) = x -36
2x-84 = x -36
2x - x = 84 -36
x = $48
