Cesar had a part-time job last year. He worked every week for the year and made $23 an hour. He worked 28 hours each week. Cesar
Naddika [18.5K]

Answer:

D. $2,511

Step-by-step explanation:

First off, we need to write down the facts we know.

There are about 52.177 weeks in a year

Cesar works 28 hours each week

Cesar makes $23 an hour

There are 12 months in a year

Cesar has $3,360 after his monthly expenses

To figure out how many hours are in a "work year," multiply the number of work hours in a week by the number of weeks in a year. In other words, multiply Cesar's 28 hour work week by about 52.177 weeks. That makes 1,456 hours in his work year. That means he makes $33,492 a year. If you multiply $2,511 by the months in a year (12), you get $30132. Finally, subtract his annual salary by $30132 to get $3,360, which is what was left of Cesar's earnings after paying all of his monthly expenses.

An instructor believes the distribution of scores on her final exam will have mean 62 and standard deviation 7. Fred is a studen
OLga [1]

Answer:

a) P(47

And then the probability that Fred will not score between 47 and 77 is

1-0.968 = 0.0321

b) P(45

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".  

Part a

Let X the random variable that represent the scores of a population, and for this case we know the distribution for X is given by:

X \sim N(62,7)  

Where \mu=62 and \sigma=7

We are interested on this probability  on the probability that Fred will not score between 47 and 77. So we can begin finding this probability

P(47

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(47

And we can find this probability on this way:

P(-2.143

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2.143

And then the probability that Fred will not score between 47 and 77 is

1-0.968 = 0.0321

Part b

P(45

And we can find this probability on this way:

P(-2.429

And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.  

P(-2.429
