Answer:
5 units right and 2 units down
Answer: $2.95
Step-by-step explanation:
Given: Probability of losing the $7 =
Probability of winning $14 =
Then, the expected value = (- $7) x ( Probability of losing the $7) + $14 x(Probability of winning $14)
=
=
=
∴ If a doctor pays $7 that the outcome is an odd number, the doctor's
expected value is $2.95.
70 mi / 3 h = 23.33 miles / hour
① 15² = 4² + 2(32) x
225 = 16 + 64x
-64x = 16 - 225
-64x = -209
x = 209/64
② 105 = 45 + 5x
-5x = 45 - 105
-5x = -60
x = 60/5
x = 12
