Well, this is a stem and leaf problem.
The numbers are 20, 28, 29, 29, 31, 32, 36, 41, and 42.
In order to solve for the mean, we find the average and we add the numbers together and divide by 9(there are 9 numbers).
The mean is 32.
The median is the middle number, or 31.
Answer:
A dictionary has the mass of about 1 killo so the book!
Step-by-step explanation:
The 5 - number summary :
Min____ Q1 ___ median ____ Q3 ____ max
7 ______ 9 _____ 12 _______ 15 _____ 18
Answer:
Hence, from the 5 number summary, about 75% of sons have fewer than 15 stylist.
Step-by-step explanation:
Explaining the table :
Minimum number of stylist salons have = 7
Maximum number of stylist = 18
Q1 = first quartile, (25 /100) ;About 25% of salons have fewer Than 9 stylist
Q2 = second quartile or median ; About 50% of salons have fewer Than 12 stylist
Q3 gives the 75th percentile value.
Q3 = third quartile (75/100) ; About 75% of salons have fewer Than 15 stylist
<h3>answer.</h3>
•given that is smallest angle of rotational symmetry for a regular polygon is 30
•we have to find the number of side does the regular polygon have
•if we can rotate of figure around a center point be fewer than 360° and the figure appears and change then the figure has the rotation symmetry
<h3>Hence,12 number of sides the polygon.</h3>
no. of side= 360/ smallest angle at centre=12
