Answer:
7.83 km/h
Step-by-step explanation:
Let v = average speed for first part, v' = average speed for second part.
Given that v' = v - 15, the distance covered by the first part d = 350 km. The distance covered in the second part d' = 470 km - 350 km = 120 km.
Since both parts are covered in the same time,
d = vt and d' = v't = (v - 15)t
So, 350 = vt (1) and 120 = vt - 15t (2)
substituting vt = 350 into (2), we have
120 = 350 - 15t
collecting like terms, we have
15t = 350 - 120
simplifying, we have
15t = 230
dividing through by 15, we have
t = 230/15
t = 15.33 h
Since d' = v't, then
v' = d'/t
= 120 km/15.33 h
= 7.83 km/h
So, the average speed for the second part of the journey is 7.83 km/h
Here's the answer:
A. There are 3 favorable outcome for 2 heads, 1 tail (3/8 or 0.375 probability)B. There is 1 favorable outcome for 3 heads (1/8 or 0.125 probability)C. There are 3 favorable outcome for 2 tails, 1 head (3/8 or 0.375 probability)D. There is 1 favorable outcome for 3 tails (1/8 or 0.125 probability)E. Sum of probabilities = A+B+C+D
Sum of probabilities = 0.375 + 0.125 + 0.375 + 0.125Sum of probabilities = 1
A and C are the same, they both have 3/8 probability. As well as B and D, both have 1/8 probability.
