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:
A
Step-by-step explanation:
Since both graphs are straight lines passing through the origin, then they both display a proportional relationship
The value of k is 735 feet.
<h3>What is a scale drawing? </h3>
A scale drawing is a smaller image in terms of dimensions of a bigger image / building / object.
The scale of the drawing = original dimensions / dimensions of the scale drawing
<h3>What is the value of k? </h3>
The value of k = height of the antenna / length of the antenna in the model
750 / 1..02 = 735 feet

Answer:
x = 48°
Step-by-step explanation:
the sum of all angles must be 180°
180 - 69 - 63 = 48
Using the De Moivre's Theorem, let us work out for the fourth roots of 81(cos 320° + i sin 320° ).
zⁿ = rⁿ (cos nθ + i sin nθ)
z⁴ = 81(cos 320° + i sin 320° )
z = ∜[81(cos 320° + i sin 320° )]
= ∜[3^4 (cos 4*80° + i sin 4*80°)]
= 3(cos 80° + i sin 80°)
