$6.25 × 4 = $25 per day.

If Andrew works 5 days per week, then he earns

$25 × 5 = $125 per week.

Find the slope of a line parallel to 3x – y = 1.

Andrew [12]

The answer is B, because you must put the equation into the y=mx+b order so you subtract -3x on both sides to be left with -y=-3x+1 and you then divide the entire equation (both sides) by -1 because y cannot be negative which leaves you with y=3x-1 so the slope id 3 and the y intercept is -1

Barron's reported that the average number of weeks an individual is unemployed is 17.5 weeks. Assume that for the population of

Olin [163]

Answer:

$P(16.5$

And using the normal standard table or excel we find the probability:

$P(-1.768< Z< 1.768) = P(Z$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the avergae number of weeks an individual is unemployed of a population, and for this case we know the distribution for X is given by:

$X \sim N(17.5,4)$
