MPA is a right angle 90 + (1/2x +15) + (2x-50) = 180

                                - 90                                        -90

                                          (1/2x + 15) + (2x - 50) = 90

                                                    - 15            -50   -65

                                                              1/2x + 2x = 90

                                                         2&1/2x (2.5) = 90

The Lake Placid Town Council decided to build a new community center to be used for conventions, concerts, and other public events, but considerable controversy surrounds the appropriate size. To provide structure for the decision process, the council narrowed the building alternatives to three sizes: small, medium, and large. Everybody agreed that the critical factor in choosing the best size is the number of people who will want to use the new facility. The town council suggested using net cash flow over a 5-year planning horizon as the criterion for deciding on the best size. The following projections of net cash flow (in thousands of dollars) for a 5-year planning horizon have been developed.All costs, including the consultant's fee, have been included.
Demand Scenario
Center Size Worst Case Base Case Best Case
Small 400 500 660
Medium -250 650 800
Large -400 580 990
a) What decision should Lake Placid make using the expected value approach?
b) Construct risk profiles for the medium and large alternatives. Given the mayor's concern over the possibility of losing money and the result of part (a), which alternative would you recommend?
c) Compute the expected value of perfect information. Do you think it would be worth trying to obtain additional information concerning which scenario is likely to occur?

Explain why the formulas for sample variance and population variance are different.
A. Variance is defined as the mean deviation, and, for a population, is computed as the sum of deviations divided by N. The sample variance will be biased and will consistently underestimate the corresponding population value.
B. Variance is defined as the mean squared deviation, and, for a population, is computed as the sum of squared deviations divided by N. The sample variance will be biased and will consistently underestimate the corresponding population value.
C. Variance is defined as the mean squared deviation, and, for a population, is computed as the sum of deviations divided by N. The sample variance will be biased and will consistently underestimate the corresponding population value.

Answers

Answer:

The answer is "option C".

Step-by-step explanation:

Distinctions are also the mean squared variance just are calculated as the number of standard differences divided by "N" and for a population. After all, if a sample uses this very same definition.

Its standard deviation would become partially skewed as well as the resulting community value becomes continuously underestimate. Its experimented formula consequently includes a correction modification for a bias. Its modification involves dividing by instead of n.

[tex](f\circ g)(4)=31[/tex]

Step-by-step explanation:

Composite Function

Given f(x) and g(x) real functions, the composite function named fog(x) is defined as:

[tex](f\circ g)(x)=f(g(x))[/tex]

For practical purposes, it can be found by substituting g into f.

We have:

[tex]f(x)=3x+1[/tex]

[tex]g(x)=x^2-6[/tex]

Computing the composite function:

[tex](f\circ g)(x)=f(g(x))=3(x^2-6)+1[/tex]

Operating:

[tex](f\circ g)(x)=3x^2-18+1[/tex]

Operating:

[tex](f\circ g)(x)=3x^2-17[/tex]

Now evaluate for x=4

[tex](f\circ g)(4)=3(4)^2-17=48-17[/tex]

[tex]\boxed{(f\circ g)(4)=31}[/tex]

Which equation is equivalent to the equation 6x+9=12?

Answers

Answer:

x=1/2

Step-by-step explanation:

The measures of two angles are represented by the expressions (5x + 24)° and (9x − 17)°. If the two angles are equal, what is the value of x?

Answers

Answer:

x=10.25

Step-by-step explanation:

Angle 1 = (5x+24)°

Angle 2 = (9x-17)°

The two angles are equal. It means,

(5x+24)°=(9x-17)°

Taking like terms together,

5x-9x=-17-24

-4x=-41°

Dividing each side by -4

x=10.25°

So, the value of x is 10.25.
