If we are already two thirds of the way there, there is still (one minus two thirds) one thirds of the way still to go. Providing we're moving at the same speed throughout the entire journey, we will take one third of 73/4 hours to get to Boston.
One third of 73/4 hours
=⅓ x 73/4 hours
=73/12 hours
=6 1/12 hours
Or 6 hours 1/12 of 60 minutes
=6 hours 5 minutes
Or 365 minutes to reach Boston.
About 127 inches. use the formula: r squared times 3.14 divided by 2. aka the formula to find area of a circle divided by two because it only covered 30 mins
Using the binomial distribution, the probabilities are given as follows:
- 0.3675 = 36.75% probability that more than 4 weigh more than 20 pounds.
- 0.1673 = 16.73% probability that fewer than 3 weigh more than 20 pounds.
- Since P(X > 7) < 0.05, it would be unusual if more than 7 of them weigh more than 20 pounds.
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
The values of the parameters for this problem are:
n = 10, p = 0.4.
The probability that more than 4 weigh more than 20 pounds is:
In which:
Then:
Hence:
0.3675 = 36.75% probability that more than 4 weigh more than 20 pounds.
The probability that fewer than 3 weigh more than 20 pounds is:
P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0061 + 0.0403 + 0.1209 = 0.1673
0.1673 = 16.73% probability that fewer than 3 weigh more than 20 pounds.
For more than 7, the probability is:
Since P(X > 7) < 0.05, it would be unusual if more than 7 of them weigh more than 20 pounds.

The answer to your question is,
Babysitting. If you take $250 and divide it by 40, since it is the monthly rate of how much the person would earn, it would mean you'd get $6.25 hourly. The first is $5.67, and the second is $5.33.

Hello,
I suppose you mean -1! else f(x)=f^1(x)
y=x²-81
-> x=y²-81 (exchahge x and y)
->y²=x+81 (solve for y)
It is because (f^-1)(x) is not a function!
with x>=-81
