Answer:
-21/4
Step-by-step explanation:
Box and whiskers plots use five number summaries. The first number is:
1:Minimum
2.Quartile 1
3.Mean
4.Quartile 2
5.maximum
Quartile are simple to get.
If your set of numbers is:
2,3,3,6,8,8,11
Then find the mean
2 3 3 |6| 8 8 11
Find the mean of the left side of of mean.
2 |3| 3 3 =Quartile 1
Then the right side
8 |8| 11 8 =Quartile 2
-----------------------------------------------
Your 5 number summary is 2,3,6,8,11
Plot them on the number line, but put a line above where the dot would go. take the 3 middle lines and connect to make a box. The lines on the outside of the box are the whiskers, AKA distributed data.
Answer:
20 inches by 28 inches
Step-by-step explanation:
The current size of the picture is 5 inches by 7 inches
If we want to enlarge the picture by a factor of 4, the perimeter will also increase by the factor of 4.
New dimension = 4(old dimensions)
= 4(5 inches by 7 inches)
= 20 inches by 28 inches
Hence, the size of the enlarged picture is 20 inches by 28 inches.
Answer:
(2x-5)(2x+5)=0
Step-by-step explanation:
