It takes you 4.8 hours to reach New York
Step-by-step explanation:
The given is:
- It is 240 miles from Boston to New York
- You drive at a speed of 50 mph
We need to find how long would it take you to reach New York
Distance (d) = speed (v) × time (t)
∵ The distance between Boston and New York is 240 miles
∴ d = 240
∵ You drive at a speed 50 miles per hour
∴ v = 50
- Substitute these values in the rule of the distance above
∴ 240 = 50 × t
- Divide both sides by 50
∴ 4.8 = t
∴ The lime of the trip is 4.8 hours
It takes you 4.8 hours to reach New York

Answer with Step-by-step explanation: Mel had $35 and withdrew $200 from his bank account. So, total money Med had=$(35+200)
= $235
He bought a pair of pants for $34.00, 2 shirts for $16.00 each, and 2 pairs of shoes for $24.00 each. Cost of 1 shirt=$16 Cost of 2 shirt=$32 Cost of 1 pair of shoe=$24 Cost of 2 pair of shoes=$48 Total money Med spent=$(34+32+48)
=$114
Total money Med is left with=Money he had-Money he spent =$(235-114)
= $121 Hence, money Mel had at the end of the shopping day is: $121

Answer:
so at the long run we can conclude that the best option is :
A) win 0.20 cents per play
Step-by-step explanation:
Previous concepts
The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.
The variance of a random variable X represent the spread of the possible values of the variable. The variance of X is written as Var(X).
Solution to the problem
Let X the random variable who represent the ampunt of money win/loss at the game defined.
The probability of loss $3.00 for this game is 0.2 and the probability of win is 1-0.2=0.8 and you will recieve $1.00 if you win. The expected value is given by:
And for this case if we replace we got:
so at the long run we can conclude that the best option is :
A) win 0.20 cents per play
