Answer:
Penny will walk 2 and 1/8 miles in one hour.
Step-by-step explanation:
4 and 1/4 divided by two = 2 and 1/8
Using the binomial distribution, it is found that there is a 0.03125 = 3.125% probability that all the nickels will land with heads facing up.
For each coin, there are only two possible outcomes, either it lands on heads, or it lands on tails. The landing of a coin is independent of other coins, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
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.
In this problem:
- 5 nickels, hence
.
- They are equally as likely to land on heads or tails, hence

The probability that all the nickels will land with heads facing up is P(X = 5), hence:


0.03125 = 3.125% probability that all the nickels will land with heads facing up.

Answer:
x=6
Step-by-step explanation:
Every point on a vertical line has the same x-value. Use the x-value of the point to find the equation of the vertical line.
x
=
6
Secant
Remember it by linking the third letter:
SeCant = 1/Cos
CoSecant = 1/Sin
CoTangent = 1/Tan
The correct option is: Option (C)

Explanation:
It is the property of log that if it contains the fraction, it can be expressed as the difference of the log of numerator and the log of denominator.
The general form is:

Hence the correct answer is
