A random sample of n = 16 scores is obtained from a parent population with σ = 12. If the sample mean is 6 points greater than the population mean, what is the z-score for the sample mean?

Answers

Answer 1

Answer:

0.5

Step-by-step explanation:

Sample mean, x = 6 points greater than population mean ;

Population mean, m = 16

Standard deviation, s = 12

Zscore = (sample mean - population mean) / standard deviation

Zscore = (x - m) / s

x = 16 + 6 = 22

Zscore = (22 - 16) / 12

Zscore = 6 /12

Zscore = 0.5

Answers

Answer:

y=2.5x+3

Step-by-step explanation:

(0,3) shows the y-intercept of +3

Use slope formula to find the slope:

8-5.5/2-1 = 2.5

therefore the M (slope) is 2.5

Answer:

y = 2.5x + 3

Step-by-step explanation:

y2 - y1/x2 - x1 = slope

5.5 - 3 = 2.5

2 - 1 = 1

2.5/1 = 2.5

8 = 2.5(2) +b

8 = 5 + b = 3

Can someone please help me with this paper? (Instructions are in Project Part 5)
Based upon the following article and the project I previously completed:
JUGGLING A career with an education is a challenge.
In the past, working adults returning to college had to quit their jobs to pursue a full-time degree, or commute to a campus for classes at night or on weekends. Today, given the flexibility of online education, it's no surprise that – as U.S. News data show – it's those very working professionals who are drawn to the virtual classroom.
[ DISCOVER questions to ask about flexibility in online programs. ]
Various data submitted to U.S. News in an annual survey contribute to a detailed profile of the average student in ranked online bachelor's programs who enrolled between July 2015 and June 2016.
(JORDAN FRIEDMAN/USN&WR)
Among the 227 online bachelor's programs that provided student age data to U.S. News, the average was 32 years old. That's significantly older than the traditional college student who's fresh out of high school.
Career aspirations also remain the primary motivation for students to pursue an online degree, according to one 2016 survey by Aslanian Market Research and the Learning House. Online undergraduates at ranked programs are often several years out of high school, and a vast majority – 84 percent, on average – are employed when they enroll, according to data submitted to U.S. News by 69 online colleges.
[ LEARN WHY online learning offers some a second shot at college. ]
But for most online bachelor's students, the online program isn't their first attempt at college. Typically, they already have some college credit under their belts. Transferring credits into a program is common, and experts say it's easier to do if your previous school has regional rather than national accreditation.


(JORDAN FRIEDMAN/USN&WR)

For many online undergraduates, online education provides a second chance at college. On average, 95 percent of new entrants at ranked online schools previously took college courses. It's much rarer for an online student, the data suggest, to enroll full time in an online bachelor's program straight out of high school, as they would for a traditional program.

While the average percentage of new students who enrolled in ranked programs as first-time students was 5 percent for the 2015-2016 school year, at most programs it's an even smaller proportion, according to the data.

[ EXPLORE five tips to succeed in online courses. ]
Most of the time, the data illustrate, students in ranked online bachelor's programs choose a health- or business-related major. Sixty-eight of the 220 ranked online colleges that submitted these data to U.S. News reported health and related professions as the most popular major, and 65 schools out of 220 indicated business.
(JORDAN FRIEDMAN/USN&WR)
Below are more data that help portray the typical student enrolled in a ranked online bachelor's degree program, based on the averages among schools that submitted these data. A majority are female and based in the U.S. And, an average of 10 percent are veterans or active service members, though most schools reported even lower percentages.

Answer:

Step-by-step explanation:

IT can be easy to compromise your experience in graduate school or work because you’re trying to get the most you can out of both experiences at once. Especially since you’re essentially doubling the demands and responsibilities in your life for the duration of your degree. Working full-time while also studying full-time clearly requires a lot of effort. Putting so much of your mental and physical energy into this uneasy arrangement can quickly leave you feel.

The flexibility of your employer and your grad program are critical factors in your ability to balance the two endeavors. If your employer understands that you will have academic demands and your will sometimes require shifts in schedule or occasional personal days to deal with school-related obligations, it will make the prospect of studying that much easier. Similarly, finding a graduate program that can accommodate some of the requirements of your work life can make a big difference. That said, finding out that your boss won’t let you shuffle some work hours so that you can attend a 12:30 class twice a week is not something you want to discover after enrolling. It’s best to start talking with your managers about your graduate study plans early, while also researching schools that offer worker-friendly programs (evening or weekend classes, online courses or components, and part-time options). Even if class schedules appear to complement your work schedule, be cognizant of the scheduling issues that can arise from out-of-the-classroom requirements, such as field research, practical experience components, or group projects.  

Given the fatigue and stress involved with studying and working full-time, it’s important to recall your motivations for taking this approach, and to regularly evaluate your ability to continue at this pace. If you are really finding it too much to handle, remember that it’s usually possible to reduce your course load once you’ve started your studies and in consultation with your advisor and program director. Keep in mind that shifting the number of credit hours you take each term may also shift your eligibility for some financial aid and impact the time it takes to complete your degree.

La casa de prestamos la mejor cobra el 7% de interes mensual.Es decir por cda 100 paga solo 7 pesos

Answers

Responder:

Por favor, consulte la explicación.

Explicación paso a paso:

Dado que :

Los mejores cargos por préstamos hipotecarios:

Interés mensual = 7%

Intereses pagados sobre capital de 100 pesos

Intereses pagados = principal * tasa de interés

Intereses pagados = 100 * 7%

Intereses pagados = 100 * 0.07

Intereses pagados = 7 pesos

De ahí que los intereses pagados por un préstamo de 100 pesos sean 7 pesos

I need the answer for Number six

Answers

Step-by-step explanation:

Although I can't give you a written answer, here's how you do it.

For y = -x + 7,  we know 7 is our y coordinate, so place a point on 7 on the y axis.

-x is equal to -1/1, so when graphing the line, go down 1 over 1 and place your point. Continue until you reach the edge of the graph.

For 5x + 5y = 10, subtract 5x from the left side of the equation. This will leave you with:

5y = -5x + 10. Divide every term by 5, leaving you with y = -x + 2. Your teacher may want you to phrase this as y = 2 - x.  2 is your y coordinate, and once again -x is -1/1. Start at 2 and go down 1 over 1 on the graph.
