Explanation:
The median is the vertical line inside the boxplot. This vertical line is at 76.
The median does not have to be at the exact midpoint of the box, as it could be much closer to one of the edges. All that matters is the median is between Q1 and Q3
Q1 = left edge of the box
Q3 = right edge of the box
The min and max are the tips of the left and right whiskers respectively. This is when there are no outlier island points to either side.
Answer:
d
Step-by-step explanation:
Given y is directly proportional to x² then the equation relating them is
y = kx² ← k is the constant of proportion
To find k use the condition y = when x =
, then
= k(
)² =
k ( multiply both sides by 8 )
1 = 2k ( divide both sides by 2 )
k =
y = x² ← equation of proportion
When y = , then
=
x² ( multiply both sides by 2 )
9 = x² ( take the square root of both sides )
x = ± = ± 3
with positive value x = 3 → d
