Answer:

1, 3, 5, 7, 9

Step-by-step explanation:

$a_n = 2n - 1$

n = 1:

$a_1 = 2(1) - 1 = 2 - 1 = 1$

n = 2:

$a_2 = 2(2) - 1 = 4 - 1 = 3$

n = 3:

$a_3 = 2(3) - 1 = 6 - 1 = 5$

n = 4:

$a_4 = 2(4) - 1 = 8 - 1 = 7$

n = 5:

$a_5 = 2(5) - 1 = 10 - 1 = 9$

Answer: 1, 3, 5, 7, 9

P(X > 25) = 0.69

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 zscore 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 pvalue, we get the probability that the value of the measure is greater than X.

The sale prices for a particular car are normally distributed with a mean and standard deviation of 26 thousand dollars and 2 thousand dollars, respectively.

This means that $\mu = 26, \sigma = 2$
