The length of each of the legs of an isosceles triangle is represented by the
expression 6x – 2 inches. The length of the base of the isosceles triangle is
represented by the expression 3x + 1 inches. The perimeter of the isosceles
triangle is 42 inches. What is the length of the base?
Answers
Answer:
10 inches
Step-by-step explanation:
6x-2+6x-2+3x+1=42
12x-4+3x+1=42
15x-3=42
15x=45
x=3
Plug x=3 into 3x+1
3*3+1
9+1=10
Length of base is 10 inches

A math teacher at George Washington Middle School asked boys in the 6th and 7th grades to report their shoe size. She used the results to create these histograms
Which conclusion best supported by the histograms?
A as boys get older, shoe sizes become more normally distributed with fewer large outliers.
B As boys get older, shoe size range, defined by the minimum and maximum, decreases
C As boys get older, shoe sizes increase and the distribution remains relatively unchanged.
D As boys get older, shoe size distribution becomes more spread with more large outliers
Answers
Answer:
As boys gets older, shoe sizes becomes more normally distributed with fewer large outliers.
Step-by-step explanation:
A visual analysi ls of the histogram distribution provided, we can observe that size distribution of 6 graders is positively skewed (right tailed) as outliers seems more to the right(large sizes). However, the second graph is balanced with a normal or symmetric distribution representing older age (7th graders). Hence, we can conclude that as the boys gets older, they attain normality in terms of their shoe sizes. And the outliers which are characterized by the first histogram having vanished or reduced.

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 probabilityWe 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.

Step-by-step explanation:
27 no costume, 112 exactly one costume, 3 more than one costume.
27+112+3=142
There were a toal of 142 customers. 112+3=115 visitors purchased one or more costumes costumes.
Probability the next visitor will purchase one or more costumes:
115/142=0.809859
0.809859 times 100% = 80.9859%
which rounds to 81%
