If a, b and c are positive integers for which (a,b,c) is the only

ordered triple such that 6a +9b + 20c = 61, then what is

a+b+c?

If *a*, *b*, and *c* are all positive integers and 6*a* + 9*b* + 20*c* = 61, then right away you know *c* < 3, because if *c* = 3, then 20*c* = 60, and there are no solutions for *a* and *b*.

So consider two cases:

• If *c* = 2, then we're left with 6*a* + 9*b* = 21.

• If *c* = 1, then 6*a* + 9*b* = 41.

We have gcd(6, 9) = 3, but 41 is prime and 3 does not divide 41. So we throw out the second case.

This leaves us with 6*a* + 9*b* = 21. Notice that if *a* = *b* = 1, then 6*a* + 9*b* = 15. Add 6 to both sides to get 21. So *a* = 2, *b* = 1, and *c* = 2, and hence *a* + *b* + *c* = **5**.

g A circle is a special case of an ellipse. Explain how a circle is different from other ellipses.

**Answer:**

Main difference between circle & ellipse

**Step-by-step explanation:**

Circle is a line forming a close loop, all points on the loop line are at equal distance from the centre, that distance is called Radius. Eg : Wheel

Ellipse is also a close loop line, such that distance of locus of all points on the plane to two fixed points (foci) always sum up to same constant. ** **Eg : Orbits of planets

**Cricle **is the round **shape entity** in which it contains only radius and **double **of radius is diameter Thus below explanation is the answer to the Question

Explanation:

Cricle is the mostThus we conclude that **cricle **is totally **different** from** ellipse**

Research shows that many banks are unwittingly training their online customers to take risks with their passwords and other sensitive account information, leaving them more vulnerable to fraud (Yahoo, July 23, 2008). Even web-savvy surfers could find themselves the victims of identity theft because they have been conditioned to ignore potential signs about whether the banking site they are visiting is real or a bogus site served up by hackers. Researchers at the University of Michigan found design flaws in 78% of the 214 U.S. financial institution websites they studied.

Required:

Is the sample evidence sufficient to conclude that more than three out of four financial institutions that offer online banking facilities are prone to fraud? Use a 5% significance level for the test.

Answer:

Decision rule

Fail to reject the null hypothesis

Conclusion

The sample evidence is not sufficient to conclude that more than three out of four financial institutions that offer online banking facilities are prone to fraud.

Step-by-step explanation:

From the question we are told that

The sample size is n = 214

The sample proportion is p = 0.78

The level of significance is [tex]\alpha = 0.05[/tex]

Generally the population proportion is mathematically represented as

[tex]p = \frac{3}{4} =0.75[/tex] (gotten from the statement ''three out of four'' in the question)

The null hypothesis is [tex]H_o : p = 0.75[/tex]

The alternative hypothesis [tex]H_a : p > 0.75[/tex]

Generally the test statistics is mathematically represented as

[tex]z = \frac{\^{p} - p}{ \sqrt{\frac{p(1-p)}{n} } }[/tex]

=> [tex]z = \frac{0.78- 0.75}{ \sqrt{\frac{ 0.75(1-0.75)}{214} } }[/tex]

=> [tex]z = 1.01[/tex]

Generally the p-value is mathematically represented as

[tex]p-value = P(Z > z )[/tex]

=> [tex]p-value = P(Z > 1.01 )[/tex]

From the z-table

[tex]P(Z > 1.01 ) = 0.15625[/tex]

So

[tex]p-value = 0.15625 [/tex]

From the obtained values we see that [tex]p-value > \alpha[/tex] hence we fail to reject the null hypothesis

Therefore we can conclude that the sample evidence is not sufficient to conclude that more than three out of four financial institutions that offer online banking facilities are prone to fraud.

Jeffrey thinks that the largest place value that 8.21 and 19.5 have in common is the tens place Austin thinks that the largest place value they have in common is the ones place

**Answer:**

Austin is correct.

**Step-by-step explanation:**

19.5 has a tens, ones, and tenths place. 8.21 has a ones, tenths, and hundredths place.

**Answer:**

Neither are correct.

**Step-by-step explanation:**

8.21:

Tens Place - 0

Ones Place - 8

Tenths Place - 2

Hundredths Place - 1

19.5:

Tens Place - 1

Ones Place - 9

Tenths Place - 5

Hundredths Place - 0

None of the places are in common, so neither Jeffery nor Austin is correct.

Dave owns Dave's Donut Shop and must make decisions about how much to charge for donuts. As a businessowner he wants to attract a lot of customers as well as make a lot of money (revenue). The amount of revenue Dave makes can be modeled by the equation R = (p-1)(200 - 40p), where p represents the price of one donut and R represents the total revenue. Use as many strategies as you can to figure out the questions below. 0 At what price will Dave break even (make no revenue)? How much should Dave charge to maximize his revenue? What is the most money Dave can make? Dave made $100 from donut sales. How much must he have charged per donut?

**Answer:**

2430

**Step-by-step explanation:**

The **revenue **is the **amount of money **generated by an organization from **sales or services** made in a **specific time**. The conclusion from the computation made are:

Given that:

[tex]R = (p - 1)(200 - 40p)[/tex]

To calculate the **break even**, we set R to 0.

So, we have:

[tex](p - 1)(200 - 40p) =0[/tex]

Split

[tex]p - 1 = 0[/tex] or [tex]200 - 40p = 0[/tex]

Solve for p

[tex]p = 1[/tex] or [tex]40p = 200[/tex]

Divide by 40 in the second equation

[tex]p=1[/tex] or [tex]p =5[/tex]

The **break even price **is at **$1 and $5**

To **maximize **his **revenue**, we have:

[tex]R = (p - 1)(200 - 40p)[/tex]

Open bracket

[tex]R = 200p - 200 - 40p^2 + 40p[/tex]

Rewrite as:

[tex]R = - 40p^2+ 200p + 40p- 200[/tex]

[tex]R = - 40p^2+ 240p- 200[/tex]

Differentiate

[tex]R' = -80p + 240[/tex]

Equate to 0 and solve for p

[tex]-80p + 240=0[/tex]

[tex]-80p =- 240[/tex]

Divide by -80

[tex]p = 3[/tex]

To **maximize his revenue**, he as to **charge $3**

The **most money **he can make is calculated as:

[tex]R = (p - 1)(200 - 40p)[/tex]

Substitute [tex]p = 3[/tex]

[tex]R = (3 - 1)(200 - 40 \times 3)[/tex]

[tex]R = (3 - 1)(200 - 120)[/tex]

[tex]R = 160[/tex]

The **most money **he can make is **$160**

The **charges **he sold when he made **$100 **is:

[tex]R = - 40p^2+ 240p- 200[/tex]

Substitute 100 for R

[tex]- 40p^2+ 240p- 200=100[/tex]

Collect like terms

[tex]- 40p^2+ 240p- 200-100=0[/tex]

[tex]- 40p^2+ 240p- 300=0[/tex]

Divide through by -20

[tex]2p^2- 12p+ 15=0[/tex]

Using quadratic formula, the solution of p is:

[tex]p = \frac{-b \± \sqrt{b^2 - 4ac} }{2a}[/tex]

So, we have:

[tex]p = \frac{-(-12) \± \sqrt{(-12)^2 - 4\times 2 \times 15} }{2 \times 2}[/tex]

[tex]p = \frac{12 \± \sqrt{24} }{4}[/tex]

[tex]p = \frac{12 \± 4.90 }{4}[/tex]

Split

[tex]p = \frac{12 + 4.90 }{4}\ or p = \frac{12 - 4.90 }{4}[/tex]

[tex]p = \frac{16.90 }{4}\ or\ p = \frac{7.1 }{4}[/tex]

[tex]p = 4.225\ or\ p = 1.775[/tex]

He **charged $4.225 **or **$1.775 **to **make $100.**

They were skilled hunters, gatherers, farmers and fishers during the spring and summer; the Wampanoag system which reflects women being the backbone of the tribe. women-controlled property, and hereditary status was passed though the maternal line; there culture was based on the mother as the head of the household. Women elders could approve selection of chiefs or sachems. Women where Responsible for up to seventy-five percent of all food production in the Wampanoag Tribe. As for men they acted in most of the political roles for relations with other bans and tribes, as well as warfare. And yet when encountering the pilgrims, they showed calmness and no ambitious rather helped them survive with guidances. Teaching them how to grow corn, fishing and allowing them to hunt on their land. There was a peace treaty that lasted for 50 years; the agreement, in which both parties promised to not hurt one another. Which in the fall of 1621 the pilgrims shared a feast what is now known as Thanksgiving? However, during the transition of the colonists on Wampanoag land there was tension between the two. Pilgrims brought disease like smallpox the Wampanoags were helpless to this disease, what survivors where left they were sold as slaves and converted to the new religion leaving behind their spiritual traditions. This is where the shift happened, the English often referred to the sachem as King; yet both men and women could hold this position. However, the English settlers interpretation toward the way of the Wampanoag was about who held the highest power and how they could benefit from this power by changing there way of life.
