Answer:
(a) 5
(b) 3rd quartile
(c) 2nd quartile
Step-by-step explanation:
There are four quartiles in a box plot <em>(or box and whisker plot).</em>
The 1st is from 5 to 13
The 2nd is from 13 to 35
The 3rd is from 35 to 40
The 4th is from 40 to 48
<em />
(a) The lowest that this box plot goes is 5 <em>(between the 4 and 6)</em>
(b) 3rd quartile — we can see that the left and right borders are close together, meaning that the data values for this quartile are close together, and therefore concentrated
(c) 2nd quartile — we can see that this quartile is the widest, and therefore the data values are spread out
Answer:
1.4
Step-by-step explanation:
Answer:
y = (x-3)^2 - 17
Step-by-step explanation:
To complete the square, take the middle term bx and divide it in two. Then take the square.
x^2 - 6x - 8 has bx = -6x. Take -6/2 = -3. Square -3^2 = 9.
Now to finish completing the square add 9 and subtract 9 from one side.
y = x^2 - 6x - 8
y = (x^2 - 6x +9) -9 - 8
y = (x-3)^2 - 17
