Answer:
A boxplot is a way to show a five number summary in a chart. The main part of the chart (the “box”) shows where the middle portion of the data is: the interquartile range. At the ends of the box, you” find the first quartile (the 25% mark) and the third quartile (the 75% mark). The far left of the chart (at the end of the left “whisker”) is the minimum (the smallest number in the set) and the far right is the maximum (the largest number in the set). Finally, the median is represented by a vertical bar in the center of the box.
Box plots aren’t used that much in real life. However, they can be a useful tool for getting a quick summary of data.
How to Read a Box Plot: Steps
Step 1: Find the minimum.
The minimum is the far left hand side of the graph, at the tip of the left whisker.
Step 2: Find Q1, the first quartile.
Step 3: Find the median.
Step 4: Find Q3, the third quartile.
Step 5: Find the maximum.

Easy peasy
sub random points for x and solve for y
or solve for y and sum points for x and get y values
some easy points that work most of the time
sup
x=0
y=0
if x=0
0-4y=-18
4y=18
y=9/2
y=4.5
(0,4.5) is one point
if y=0
x-4(0)=-18
x=-18
(-18,0) is aonther
another is
(-5,2)
3 points are
(0,4.5)
(-18,0)
(-5,2)

Answer:
There were 72 kids there.
Step-by-step explanation:
This question can be solved using proportions, by a rule of three.
The number of kids and time are inversely proportional, that is, if we increase the number of kids to build the castle, the time it takes will decrease. This means that to solve the rule of three, instead of applying cross multiplication, we apply line multiplication.
We have that:
30 kids - 6 hours
x kids - 2.5 hours.
Applying line multiplication
There were 72 kids there.
Let x = width
2x + 3 = length
Area of rectangle is length times width
x(2x + 3) = 77
2x² + 3x = 77
2x² + 3x - 77 = 0
2x² + 14x - 11x - 77 = 0
2x(x + 7) - 11(x + 7) = 0
(2x - 11)(x + 7) = 0
x = 11/2, - 7
Distance/measurements can't be negative so x = 11/2
The length:
2(11/2) + 3
11 + 3
14
Your width is 11/2 feet and your length is 14 feet.
