What is the reason for an outlier in a graph?

1 answer:

7 0

It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500) while others may indicate that something unusual is happening

Find a polynomial function of least degree having only real coefficients, a leading coefficient of 1, and roots of 2-√6 , 2+ √6

horsena [70]

Answer:

$x^{4} -18x^{3}+104x^{2} -172x-100$

Step-by-step explanation:

The 3 roots are given out of which 2 are real and 1 is imaginary. For a polynomial of least degree having real coefficients, it must have a complex conjugate root as the 4th root. Therefore, based on 4 roots, the least degree of polynomial will be 4. Finding the polynomial having leading coefficient=1 and solving it based on multiplication of 2 quadratic polynomials, we get:

$\\\\x_{1} = 2-\sqrt{6} \\x_{2} = 2+\sqrt{6} \\x_{3}=7-i \\x_{4}=7+i \\\\P(x)=1(x-x_{1})(x-x_{2} )(x-x_{3} )(x-x_{4} ) \\\\=(x-(2-\sqrt{6}))( x-(2+\sqrt{6} )) (x-(7-i))( x-(7+i))\\=((x-2)+\sqrt{6})( ( x-2)-\sqrt{6} ) ((x-7)+i)( (x-7)-i)\\=((x-2)^{2} -(\sqrt{6} )^{2} )((x-7)^{2}-(i)^{2})\\=(x^{2} -4x-2)(x^{2} -14x+50)\\=x^{4} -18x^{3}+104x^{2} -172x-100\\$

Dr. Jones is interested in expanding his practice by adding a piece of radiology equipment. The basic cost of the equipment woul

inysia [295]

Answer:

Dr. Jones' projected income is US$ 56.793, projected costs are US$ 61,935.48 and projected loss is US$ 5,142.48 for the 1st year of the radiology service.

Step-by-step explanation:

1. Dr. Jones Income per year:

Income = 1,100 * 51.63

Income = US$ 56,793

2. Dr. Jones Costs

Equipment = US$ 1,564.29 loan cost monthly

Radiology tech salary = US$ 39,600 (including taxes and fringe benefits)

Variable cost = US$ 3.24 * 1,100

Equipment = 1,564.29 * 12 = US$ 18,771.48

Radiology tech salary = US$ 39,600

Variable cost = US$ 3,564

Total costs = Equipment loan cost + Radiology tech salary + Variable cost

Total costs = 18,771.48 + 39,600 + 3,564

Total costs = US$ 61,935.48

3. Dr. Jones Profit or Loss

Profit or loss = Income - costs

Profit or loss = 56,793 - 61,935.48 (Costs are higher than income)

Loss = US$ 5,142.48
