<span>A) About 25% of the fishermen caught between 25 and 30 fish.
>Since the boxplot looks symmetric, the parts are each 25%.
</span><span>B) The spread is symmetrical about the median.
>The median is 20.
20-15 = 5; 15-10 = 5
25-20 = 5; 30-25 = 5
</span><span>E) The range is 20 fish.
> The largest data is 30, smallest data is 10
Range = largest - smallest = 30-10 = 20</span>

Step-by-step explanation:
Step-by-step explanation:
you drew already the right things, you have everything.
so, what is the problem ?
the most common form of line equation is
y = ax + b
a is the slope of the line. it is expressed as the ratio
y coordinate change / x coordinate change
when going from one point to the other.
b is the y-intercept (the y value when x = 0).
once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and solve for b.
so, for the 2 marked points you showed correctly the differences :
x changes by +8 (from -4 to 4).
y changes by -2 (from 3 to 1).
so the slope is -2/+8 = -1/4
the y-intercept we also see directly in the chart : +2.

Answer: 6 apples</h3>
x = number of apples originally
50% of x = 0.50*x = amount of apples eaten = 3
0.50x = 3
x = 3/0.50 ....... divide both sides by 0.50
x = 6
You can think of 50% as 1/2. If 3 apples represent half the bag, then the full bag is 6 apples. So half of 6 is 3.
select two points on the line, and plug into this formula y2-y1 over x2-x1
