Answer:

two coins are flipped:

  • if dime land heads and nickel land heads then Allan wins
  • if dime land heads and nickel land tail then Beth wins
  • if dime land tail and nickel land heads then Carlos wins
  • if dime land tail and nickel land tail then Denesha wins

Step-by-step explanation:

The method described above is fair since the probability of each case is 0.25.

If the two coins are flipped:

  • The probability dime land head is 0.5
  • The probability dime land tail is 0.5
  • The probability nickel land head is 0.5
  • The probability nickel land tail is 0.5

Then the probability dime land heads and nickel land heads is 0.5 × 0.5 = 0.25.

The other four cases are calculated similarly and their probability is also 0.25

Allen rents a truck for 45 dollars plus .36 cents for every mile that he drives the truck. Write an equation that models this li
enot [183]

Answer:

This is a linear equation of the form y = mx + b, where m is the rate of change and b is the y-intercept, also known as the value of y when x = 0.  Our independent variable is the number of miles we travel, and we will call that x.  If we pay .20 per mile, and miles is "x", we represent that as .20x.  The 70 is the amount we will pay per day even if we drive 0 miles.  Therefore, the equation is:

y = .20x + 70.

I cannot graph this for you here.

We can choose a number of miles, say 100, and solve for our cost:

y = .20(100) + 70

y = 20 + 70

y = 90

We can expect to pay $90 if we drive 100 miles in a day.
