Complete question is attached.
Answer:
B) 8
Step-by-step explanation:
In this question, KLMN ~ PQRS. This means they are similar shapes.
From the image, we could denote that:
KL ~ PQ
LM ~ QR
Given that:
KL = 12
PQ = 30
QR = 20
LM = x
To find x, let's use tge expression:
Cross multiplying, we have:
12 * 20 = 30x
240 = 30x
To find x, let's divide both sides by 30.
8 = x
x = 8
The correct option is option B.
Answer:
Box-plot = {54, 65, 69, 73, 76}
Step-by-step explanation:
The data provided for the number of desks on each floor of Texter Corporate is as follows:
S = {54, 60, 65, 66, 67, 69, 70, 72, 73, 75, 76}
There are a total of <em>n</em> = 11 floors.
A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,
Arrange the data in ascending order as follows:
S': = {54 , 60 , 65 , 66 , 67 , 69 , 70 , 72 , 73 , 75 , 76}
The minimum value is:
Minimum = 54
The maximum value is:
Maximum = 76
As there are odd number of values the median is the middle value.
Median = 6th value = 69
The first quartile is the median of the first half of the data.
S'₁ = {54 , 60 , 65 , 66 , 67}
First quartile = 3rd value = 65
The third quartile is the median of the second half of the data.
S'₂ = {70 , 72 , 73 , 75 , 76}
Third quartile = 3rd value = 73
Thus, summarized data for the box plot is:
Box-plot = {54, 65, 69, 73, 76}
The box plot is attached below.
