We start by ordering the values.
5, 7, 8, 10, 13, 14, 17, 17, 21
Now we find the median(middle number).
Median(b): 13
(I added (b) for "base" since we need to take more medians)
The median now divides this data into two halves.
Now we take the medians of the two remaining halves.
Median(Half1): 7.5
Median(Half2): 17
Mark off the minimum and maximum.
Min: 5
Max: 21
Now graph!
Your median(Half1) is incorrect, since your median for the first half is 9. Since our median for the first half is 7.5, the answer would be Answer Choice C.
Answer:
A square has 4 sides with equal length.
So the perimeter of a square is equal to 4 times the length of one side.
Now, suppose that we know that the length of one side of the garden is x.
Then the total length of the fence that surrounds the square is:
L = 4*x.
Now let's define proportional quantities:
x and y are proportional quantities if:
x = k*y
where k is a constant of proportionality.
In the case of our problem, we have a relation between L (total length of the fence) and x (length of one side of the garden)
L = 4*x
This is a proportional relation, and 4 is the constant of proportionality.
Answer:
1.5$
Step-by-step explanation:
10 cupcakes =15$
so, 1 cupcake = 15/10
i.e. 1.5
.: 1cupcake cost = 1.5$
Answer:
12 y
Step-by-step explanation:
π. x².y = ⅓. π (½x) ².h
=> eliminate π,
x²y = ⅓. ¼x².h
=> eliminate x²,
y = 1/12 h
h = 12 y
so, height of the cone = 12 y
Let the number be y.
so,
50% × y = 7.5
move 50% to the other side
y=7.5÷50%
therefore y=15
