Using the following data on the lengths of fish (in cm) caught by local fisherman in one day, complete the questions below. 34, 23, 26, 27, 12, 18, 19, 45, 31, 20, 27, 26, 9, 6, 55, 34, 26, 37, 44, 38, 22, 13, 18, 34, 37, 31

6, 9, 12, 13, 18, 18, 19, 20, 22, 23, 26, 26, 26, 27, 27, 31, 31, 34, 34, 34, 37, 37, 38, 44, 45, 55

Complete the frequency table below, chose an appropriate class interval for your data.

How to find the average fish size using the table?

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

the answer for this is 0.25 km. : )

my answer was deleted because it was to vague the answer is 12.76 becuase its in the hundreths place. john
