A financial analyst constructs a statistical model to represent the market shares of several similar companies. She then collects data over the
next month to evaluate her model. At the end of the month, she finds that for one of the companies, the difference between her model and the
data is 5%.
She decides to collect data for an additional two months. If her model is valid, what could she expect from the total data collected after three
months?
ОА. .
The difference between the data and the model will get smaller.
OB.
The difference between the data and the model will stay the same.
OC.
It is impossible to predict how the difference between the data and the model will change.
OD.
The difference between the data and the model will get larger

Answer:

A:  angle A is 90°, angle B is 90°, angle C is 90°, and angle D is 90°

B:  angle A is 80°, angle B is 80°, angle C is 100°, and angle C is 100°

D:  angle A is 60°, angle B is 50°, angle C is 120°, and angle D is 130°

Step-by-step explanation:

The sum of opposite angles of a cyclic quadrilateral is 180°

It must satisfy the following:

A+C=180° and B+D=180°

Only choice A and B and D satisfy.

The correct options are options A, B, and D.

A quadrilateral having all its corners on a circle plus opposite angles' sum is 180° called a cyclic quadrilateral.

A) ∠A =90°

∠B=90°

∠C =90°

∠D =90°

∠A + ∠C = 180°

∠B + ∠D =180°

So, this quadrilateral can come from a cyclic quadrilateral.

B) ∠A =80°

∠B=80°

∠C =100°

∠D =10 0°

∠A + ∠C = 180°

∠B + ∠D =180°

So, this quadrilateral can come from a cyclic quadrilateral.

Similarly, options C, D, and E also can be checked whether they can come from a cyclic quadrilateral or not.

C) Cannot come from a cyclic quadrilateral since ∠A + ∠C =140°≠180°.

D) ∠A + ∠C = 180°

∠B + ∠D =180°

So,  this quadrilateral can come from a cyclic quadrilateral.

E)Cannot come from a cyclic quadrilateral since∠A + ∠C = 170°≠180°.

Therefore, The correct options are options A, B, and D.

Answer:

2.025 pints of blue paint

Step-by-step explanation:

4/5 = 80/100 or 80%

8.1 is 80% of 10.125

10.125 is the total pints of paint used.

If 8.1 of those pints of paint are white, then the rest of the paint must be blue.

Answer:

adult tickets = 118

student tickets = 354

Step-by-step explanation:

a = number of adult tickets

s = number of student tickets

a + s = 472

3a = s

substitute for s

a + 3a = 472

reduce

4a = 472

divide by 4

4a/4 = 472/4

a = 118

s = 354

Answer:

B. Decreasing; The slope of the line between points D and E is negative

Step-by-step explanation:

The graph clearly shows that the speed is decreasing between these points. This narrows down your options to either Option B or Option D. A completely vertical line has a slope of undefined. The line is not completely vertical and undefined, so Option D is incorrect. This leaves B as correct. A negative slope is a line rising right to left.

Answer:

B, C and F

Step-by-step explanation:

A constant is where a variable or number is on its own

B - 2x-4 (4 is the constant)

C - 8x+y (y is the constant)

F - 7+4x (7 is the constant)

Solution :

It is given that P(x) is said to be complete or proper probability distribution if it satisfies the following two ways :

1. [tex]$P(x) \geq 0$[/tex]

2. [tex]$\sum_z P(x) = 1$[/tex]

Now consider,

[tex]$\sum_z P(x) = 1$[/tex]

⇒ [tex]$P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)+P(x=5)=1$[/tex]

⇒ [tex]$0.61+T+0.14+0.01+0.01+0.03=1$[/tex]

⇒ [tex]$0.8+T=1$[/tex]

⇒ [tex]$T=1-0.8$[/tex]

       = 0.2

Therefore, the value of T is 0.2

Thus, option (c) is correct.

Answer:

Hо:p = 0.35

H1:p > 0.35

Step-by-step explanation:

The magazine wants to check if the the proportion of readers interested in the online edition is equal to 35% (0.35) or greater than 35% (>0.35). Denote by p, the proportion of readers interested in the online edition. Then the null hypothesis,the hypothesis that contains equal-to sign- will be Hо:p = 0.35 and the alternative hypothesis will be H1:p > 0.35.

Answer:

a) Interpret the results and determine whether or not the coefficients are significantly dif- ferent fromzero. Do the coefficients have the expected sign?

An increase in reputation by one category, increases the cost by

roughly $3,985. The larger the size of the college/university, the

lower the cost. An increase of 10,000 students results in a $2,000

lower cost. Private schools charge roughly $8,406 more than public

schools. A school with a religious affiliation is approximately $2,376

cheaper, presumably due to subsidies, and a liberal arts college also

charges roughly $416 less. There are no observations close to the

origin, so there is no direct interpretation of the intercept. Other than

perhaps the coefficient on liberal arts colleges, all coefficients have

the expected sign.

(b) What is the forecasted cost for a liberal arts college, which has no religious affiliation, a size of 1,500 students and a reputation level of 4.5? (All liberal arts colleges are private.)

7,311.17 + 3,985.20×4.5 – 0.20×1500

+ 8,406.79×1 – 416.38×1 – 2,376.51×0=$ 32,935

(c) Suppose that you switch from a private university to a public university, which has a ranking tha's 0.5 lower and 10,000 more students. What is the effect on your cost?

Roughly $ 12,400. Since over the four years of education, this

implies approximately $50,000, it is a substantial amount of money

for the average household.

(d) What is the p-value for the null hypothesis that the coefficient on Size is equal to zero? Based on this, should you eliminate the variable from the regression? Why or why not?

Using a one-sided alternative hypothesis, the p-value is 6.2 percent. Variables should not be eliminated simply on grounds of a statistical test. The sign of the coefficient is as expected, and its magnitude makes it important. It is best to leave the variable in the regression and let the reader decide whether or not this is convincing evidence that the size of the university matters

(e) You want to test simultaneously the hypotheses ha and bert - 0. Your regression package returns an F-statistic of 1.23. Can you reject the null hypothesis?

The critical value for F2,∞ is 3.00 (5% level) and 4.61 (1% level). Hence you cannot reject the null hypothesis in this case

(f) Eliminating the Size and Dlibartvariables from your regression, the estimated regression becomes 5,450.35+3,538.84 .

Step-by-step explanation:

a.An increase in reputation by one category, increases the cost by

roughly $3,985. The larger the size of the college/university, the

lower the cost. An increase of 10,000 students results in a $2,000

Volume for sphere = 4/3 Pi 3^3

y = x^2 - (x+0) (x+0)< 3 would equal x = 1.25 and y = 2.5 max

then y = 9 and x = 0 around the y axis

We find (1.25, 2.5) (0,9)

y + 1 = 0 + 1.25 + 9

y+ 1 = 10.25

radius therefore = 3^2 = 3

and surface area = pi x 9 =  28.2743338823

= 28.27cm^2 x 4 = 113.1cm

If it is a sphere you then multiple 4/3 pi r^3 is exactly the same as 4pir^2

Step-by-step explanation:

The volume of the solid is [tex]9\pi[/tex] cubic unit.

The volume of the solid obtained by rotating the curve [tex]y=f(x)[/tex] is given as,

                        [tex]V=\int\limits^b_a \pi {y^{2} } \, dx[/tex]

Given that, [tex]y=x^{2} ,a=0,b=3[/tex]

Substitute above values in volume formula.

         [tex]V=\int\limits^3_0 \pi{x^{2} } \, dx \\\\V=\pi(\frac{x^{3} }{3} )^{3} _{0}\\\\V=\frac{\pi}{3} (27-0)=9\pi[/tex]

Thus, the volume of the solid is [tex]9\pi[/tex] cubic unit.
