First one..................
<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>
Answer:

Step-by-step explanation:
we know that
Landon finished 1/2 of the test in 3/5 of an hour
so
by proportion
Find out how much of the test will he have done in one hour

First, change the mixed fraction into improper fraction
1 1/7 = 7/7 + 1/7 = 8/7
(4/7)/(8/7)
To solve, flip the second fraction, and change the division into multiplication
(4/7)/(8/7) = (4/7) x (7/8)
Multiply, and simplify
(4/7) x (7/8) = 28/56, or 1/2
1/2 is your answer
hope this helps
