What is the third term of the sequence defined by the recursive rule f(1)=2, f(n)=2f(n-1) +1

1 answer:

7 0

The function is defined recursively. In order to calulate f(3), f(2) and f(1) must be known. f(1) is given f(1) = 2 f(2) is then calculated f(2) = 2 * f(1) + 1 = 2 * 1 + 1 = 2 + 1 = 3 Finally f(3) can be calculated given f(2)=3 f(3)= 2 * f(2) + 1 = 2 * 3 + 1 = 6 + 1 = 7

- Abel says (62)3 = 65. Is he correct? Explain.

expeople1 [14]

Answer and Step-by-step explanation:

Abel is incorrect. $(62)3$ denotes that the two terms are being multiplied. Instead of multiplying, Abel added these two terms.

The correct solution would be:

$(62)(3)=186$

The best approach to this is to use the law of cosine which is stated as
c2 = a2 + b2 â’ 2ab cos(C)
distance a=176.27; distance b=222.34; angle C=38.59; distance c is the missing value.
Hence cÂ˛=176.27Â˛+222.34Â˛ -2*176.27*222.34cos38.59Â°= 138.71 miles

Let Z be the standard normal random variable. Use a probability calculator to answer the following questions: What is the probab

Softa [21]

Answer:

0.6826 = 68.26% probability Z will be within one standard deviation of average.

Step-by-step explanation:

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

What is the probability Z will be within one standard deviation of average?

This is the p-value of Z = 1 subtracted by the p-value of Z = -1.

Z = 1 has a p-value of 0.8413.

Z = -1 has a p-value of 0.1587.

0.8413 - 0.1587 = 0.6826

0.6826 = 68.26% probability Z will be within one standard deviation of average.
