Answer:
<h3>{44-55}</h3><h3>{52- 59 } are the last two interval s</h3>
Step-by-step explanation:
<h2>To get the class boundaries deduct 0.5 from the first number and add 0.5 to the second number = 4-0.5 = 3.5 </h2><h2> = 11.5 + 0.5 = 11.5 </h2><h2> = 3.5 -11.5 as in the fish class boundary .</h2><h2>same for all other boundaries</h2>
If x equals the absolute value of 2, and 2 is already in absolute value... Then Y would equal 0.7(2)=1.4
