Answer:

You lose $0.833 while Rick gains $0.833, and so Rick is not Loco

Step-by-step explanation:

There are six numbers on a dice. Thus, probability of rolling exactly one number = 1/6

Probability of rolling two is 2/6.

Rolling a 1 pays $25, and probability = 1/6

Rolling a 2 pays $5,and probability = 1/6

Rolling a 3 pays $0, and probability = 1/6

Rolling a 4 or 5 pays -$10, and probability = 2/6

Rolling a 6 pays -$15, and probability = 1/6

Thus,lets calculate the expected value;

EV = (25 × 1/6) + (5 × 1/6) + (0 × 1/6) + (-10 × 2/6) + (-15 × 1/6)

EV = - $0.833

This means you lose $0.833 while Rick gains $0.833, and so Rick is not Loco.

Yes, it is correct
alexgriva [62]

Answer:In Heather's solution to the problem, she wrote and solved an equation.

Her work is:

Step 1: 1.08(x +9.01 +0.98 +5.01) = 21.87

Solving like terms

1.08(x+15}=21.87

dividing both side by 1.08

we get

x+15=21.87/1.08

x+15=20.25

subtracting both side by 13.9198

x=20.25-15

x=5.25

According to correction

;

<u>Option 1st</u>

Myles' shoestring was 9 1/4 inches long. A piece broke off and the shoestring is now 7 5/8 inches long. How long is the piece th
Vinvika [58]

Answer:

  1 5/8 inches

Step-by-step explanation:

It can work out well to subtract integer portions and fractional portions, then combine the results.

  (9 1/4) -(7 5/8) = 9 + 1/4 - 7 - 5/8

  = (9 -7) +(1/4 -5/8)

  = 2 + (2/8 -5/8)

  = 2 -3/8

  = 1 5/8

The piece of Myles' shoestring that broke off is 1 5/8 inches long.
