The nth term (an) of the arithmetic sequence is calculated through the equation,
an = a1 + (n - 1)(d)
where an is the nth term, a1 is the first term, n is the number of terms, and d is the common difference. Substituting the known values,
a72 = 5 + (72 - 1)(3)
a72 = 218
Answer:
Step-by-step explanation:
ratio of 2:1....total of 3....so caroline gets 2/3 of the money and sarah gets 1/3 of the money. Let the total amount of money be x.
so caroline = 2/3x and sarah = 1/3x
caroline gets 45 more then sarah
2/3x = 1/3x + 45
2/3x - 1/3x = 45
1/3x = 45
x = 45 * 3
x = 135.....so the total money is $ 135
caroline gets 2/3 of it.......2/3(135) = 270/3 = $ 90
sarah gets 1/3 of it......1/3(135) = 135/3 = $ 45 <===
Answer:
The probability is an Empirical Probability
Step-by-step explanation:
The empirical probability (also know as relative frequency, or experimental probability) is the type of probability that involves the ratio of the number of outcomes in which a certain occurrence or event happens to the total number of trials, not in a theoretical sample space but in an actual experiment.
It uses the number of occurrences of an outcome within a sample set as a basis for determining the probability of that outcome.
