(01.01 MC) Monica earned $60 from a bonus plus $8.50 per hour (h) she worked this week. Which of the following expressions best
Anna11 [10]

Answer:

Option (1)

Step-by-step explanation:

Monica earned a bonus = $60

Per hour earning in addition to bonus = $8.50

Let she worked for 'h' hours this week.

Then total earning from the hourly rate = $8.50h

Total earning for the week = Earning of 'h' hours + Bonus earned

                                             = $(8.50h + 60)

Therefore, Option (1) will represent Monica's earnings for the week.

During the 2013 regular NBA season, DeAndre Jordan of the Los Angeles Clippers had the highest field goal completion rate in the
melomori [17]

Answer:

a) The probability mass function for the Binomial distribution is given as:  

P(X)=(nCx)(p)^x (1-p)^{n-x}  

Where (nCx) means combinatory and it's given by this formula:  

nCx=\frac{n!}{(n-x)! x!}  

Let X the random variable of interest, on this case we know that:

X \sim Binom(n=80, p=0.613)

b) \mu = n*p = 80*0.613= 49.04

\sigma = \sqrt{np(1-p)}= \sqrt{80*0.613*(1-0.613)}= 4.356

c) For this case we can use the following excel code:

"=BINOM.DIST(60,80,0.613,FALSE)"

And we got 0.00355

d) P(X>50) 1-P(X \leq 50)

And we can use the following excel code:

"=1-BINOM.DIST(50,80,0.613,TRUE)"

And we got 0.3718

Step-by-step explanation:

Assuming the following questions:

a) What is the probability distirbution for X?

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

The probability mass function for the Binomial distribution is given as:  

P(X)=(nCx)(p)^x (1-p)^{n-x}  

Where (nCx) means combinatory and it's given by this formula:  

nCx=\frac{n!}{(n-x)! x!}  

Let X the random variable of interest, on this case we know that:

X \sim Binom(n=80, p=0.613)

b) Using formula calculate the mean and standard deviation of X

By properties we have:

\mu = n*p = 80*0.613= 49.04

\sigma = \sqrt{np(1-p)}= \sqrt{80*0.613*(1-0.613)}= 4.356

c) Use your calculator to find the probability that DeAndre scored with 60 of these shots

For this case we can use the following excel code:

"=BINOM.DIST(60,80,0.613,FALSE)"

And we got 0.00355

d) Find the probability that DeAndre scores with more than 50 of these shots

We want this probability:

P(X>50) 1-P(X \leq 50)

And we can use the following excel code:

"=1-BINOM.DIST(50,80,0.613,TRUE)"

And we got 0.3718

There are 620 people at a play. The admission price is $2 for adults and $1 for children. The receipts totalled $960.00. How man
romanna [79]
To get the answer, divide the receipts by 2 to get the total cost for adults and divide it again to get the total number of parents who attended

Cost for adults is $480.00
Number of adults is 240

Now, to get the children, subtract the total number of people by the number of adults.
620-240=380

Number of children is 380
