otez555 [7]

Answer:

Step-by-step explanation:

She bought two tires for $35.00 each. This means that the total amount for which she bought the tires is

35 × 2 = $70

She later sold them for $65.00 each. This means that the total amount for which she sold the tires is

65 × 2 = $130

Her profit from the tires is

130 - 70 = $60

She bought rims for $75.00 each. This means that the total amount for which she bought the rims is

75 × 2 = $150

She later sold them for $136.00 each. This means that the total amount for which she sold the rims is

136 × 2 = $272

Her profit from selling the rims is

272 - 150 = $122

Her total profit is

60 + 122 = $182

The weights of steers in a herd are distributed normally. The standard deviation is 200lbs and the mean steer weight is 1000 lbs

ElenaW [278]

Answer:

0.9466 = 94.66% probability that the weight of a randomly selected steer is between 639 and 1420lbs.

Step-by-step explanation:

Problems of normally distributed samples are 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.

In this problem, we have that:

$\mu = 1000, \sigma = 200$
