<em>" Expected Payoff " ⇒ $ 1.56 ; Type in 1.56</em>

Step-by-step explanation:

Consider the steps below;

Tickets That Can Be Entered - 1 Ticket,\\Total Tickets Entered - 1000 Tickets,\\\\Proportion - 1 / 1000,\\Money One ( First Ticket ) = 820 Dollars,\\Money One ( Second Ticket ) = 740 Dollars,\\\\Proportionality ( First ) - 1 / 1000 = x / 820,\\Proportionality ( Second ) - 1 / 1000 = x / 740\\\\1 / 1000 = x / 820,\\1000 * x = 820,\\x = 820 / 1000,\\x = 0.82,\\\\1 / 1000 = x / 740,\\1000 * x = 740,\\x = 740 / 1000,\\x = 0.74\\\\Conclusion ; " Expected Payoff " = 0.82 + 0.74 = 1.56

<em>Solution; " Expected Payoff " ⇒ $ 1.56</em>

The change in average height of the trees on the farm with respect to the number of years since the trees were planted is = 7ft/yr.

<h3>What is the linear relationship?</h3>
  • A statistical word used to express a straight-line relationship between two variables is a linear relationship (or linear association).
  • Graphs and mathematical equations of the form y = mx + b can both be used to represent linear relationships.
  • In everyday life, linear relationships are quite prevalent.

The midpoint of the axis is=

  • 10+24/2
  • 34/2
  • 17

In the intercept form-

  • y= mx+b
  • y= mx+3
  • y= mx +3
  • 10 =m(1) + 3

subtracting 3 from both sides-

  • 7=m
  • Y = 7x+3

Hence, the rate of change is 7ft/yrs.
