What is the interquartile range of the sequence 5,5,8,8,13,14,16,16,19,22,23,27,31 ?
Romashka-Z-Leto [24]
Answer:
The Interquartile range is 10.
Step-by-step explanation:
First, we will need to find the mean, the mean of this sequence is 16, you will now need to find quartile 1 and quartile 3. Quartile 1 is 13, and quartile 3 is 23. Lastly, subtract Quartile 3 and Quartile 1 will be the answer.
So, 23-13=10
The Answer will be 10, the interquartile range is 10.
Hope this helps!
Answer: b. (2, 0)
<u>Step-by-step explanation:</u>
L = (-3, 3)
down 3 units means subtract 3 from the y-coordinate
new L = (-3, 0)
left 1 units means subtract 1 from the x-coordinate
newer L = (-4, 0)
reflection across x = -1 means measure the distance of the x-coordinate from x = -1 and move it to the other side that same distance. (-4 - (-1) = 3. --> -1 + 3 = 2
L' = (2, 0)
Answer:
Width = 4.5
Length = 7.5
Step-by-step explanation:
The perimeter is two times the length plus two times the width.
So 2(x+3) + 2x = 24 is the equation to solve.
2x+6+2x = 24
4x = 24-6
4x = 18
x = 9/2= 4.5
So the width = 4.5
Length = 4.5+3 = 7.5
6+5+2=13. There are 13 tennis balls in each bag. There are 3 bags. 13x3=39. Martina has 39 tennis balls in all.
