What are the minimum, first quartile, median, third quartile and maximum of the data set 3,5,7,8,12,13,14,18,21
Wittaler [7]
Answer:
3, 7, 12, 14, 21
Step-by-step explanation:
3 is the minimum value of the data set.
The median is 12. (it is in the middle of 3 and 12 if you look at the question)
The first quartile is 7 (if you count, it is equidistant from either end)
the third quartile is 14. (it is in the middle of 12 and 21 if you look at the question)
21 is the maximum value of the data set.
Answer: 3 is minimum, 7 is first quartile, 12 is median, 14 is third quartile, and 21 is maximum.
15. 3x - 2y = -2
3x - 3x - 2y = -3x - 2
-2y = -3x - 2
-2 -2
y = 1.5x + 1
y - y₁ = m(x - x₁)
y - 3 = ⁻²/₃(x - (-2))
y - 3 = ⁻²/₃(x + 2)
y - 3 = ²/₃(x) - ²/₃(2)
y - 3 = ⁻²/₃x - 1¹/₃
+ 3 + 3
y = ⁻²/₃x + 1²/₃
16. 230 = 0.2s + 150
- 150 - 150
80 = 0.2s
0.2 0.2
400 = s
17. y = 2x + 2
Answer:
Step-by-step explanation:
Not QUITE a parabola . but up until y = 4 it is close
Vertex = (-7-10)
Vertex form of parabola
y = a ( x+7)^2 -10 find a integer-coordinat point to calculate 'a'
I'll use -18,0
0 = a(-18+7)^2 -10
0 = 122 a -10 a = 10/122
y = 10/122 (x+7)^2 - 10 see graph below:
She will most likely round to 40 since 37 is closet to that
