What is 16=10/3a equal

1 answer:

5 0

1. You would multiply both sides by 3a to kill the fraction: (3a)16=10/3a(3a)

2. 3a times 16 equals 48a, and 10/3a times 3a equals 10, so your new equation is 48a=10

3. Now since you want to get a by its self, you would divide both sides by 48

4. The new equation is now a=10/48

5. That can be simplified to a=5/24

What is the probability of obtaining threethree tailstails in a row when flipping a coin? Interpret this probability.

Korolek [52]

Answer:

P=0.125

If it is repeated 10,000, it is expected "3 tails in a row" about 1,250 times.

Step-by-step explanation:

When flipping a coin a number of times, we can modeled this as a random variable with a binomial distribution.

In this case, we have to calculate the probability of 3 consecutive tails. If we define p as the probability of getting a tail (which has a value of p=0.5 if it is an unbiased coin), the probability of getting 3 tails in a row is:

$P=p^3=0.5^3=0.125$

If that event of "flipping a coin 3 times" is repeated 10,000 times, we can expect to have 3 tails in a row about 1,250 times:

$E=nP=10,000*0.125=1,250$

because we expect 0.125 events of this type for every try, so we can multiply this probability (or expected frequency) by the number of trials and we get the expected number of events described.

Fed [463]

Answer:

Part 1) The number of minutes in a month must be greater than 50 in order for the plan A to be preferable

Part 2) The number of minutes in a month must be equal to 50 minutes

Step-by-step explanation:

The question is

Part 1) How many minutes would Kendra have to use in a month in order for the plan A to be preferable? Round your answer to the nearest minute

Part 2) Enter the number of minutes where Kendra will pay the same amount for each long distance phone plan
