Let Y1, Y2,...Yn denote a random sample size n from a population with a uniform distribution on the interval (0,θ). Consider Y(1)=min(Y1, Y2,...Yn), the smallest order statistic. First derive E(Y(1)). Find a multiple of Y(1) that is an unbiased estimator for θ.

Answer:

she will arrive at her work in approximately 38.4 minutes

Step-by-step explanation:

you divide her mph by 60 to see how fast she is traveling per minute. she traveled .25 miles per minute. you divide the total distance she is biking by the distance she travels per minute.

15/60=0.25

9.6/0.25= 38.4

If x and y be  i.i.d. unif(0, 1), then the covariance of x + y and x - y is zero.

Yes, x y are x y independent studysoup.

Here  x and y be i.i.d. unif(0, 1)

The i.i.d stands for independent and identically distributed

unif means that the uniformly distributed

Here x and y are i.i.d unif (0,1)

The covariance is defined as the relationship between the two random variables . Therefore, variance of one variable is equal to the change in another variable

Here we have to find the covariance of x + y and x - y

According to the properties of covariance

Cov(x+ y, x - y) = Cov (x, x) + Cov(y, x) - Cov(x, y) - Cov(y, y) = 0

Because Cov(x, x) = Cov (y, y)

Cov(y, x) = Cov(x, y)

Therefore, the covariance of x+y and x - y is 0.

Answer:

The cellphone towers height is 1020 ft.

Step-by-step explanation:

This question is solved using proportions, by a rule of three.

A 10-ft post casts a 14-inch shadow.

Each feet has 12 inches, which means that a post with 10 feet will cast a 14/12 = 1.167 ft shadow. How tall is the cell-phone tower with a 119-feet shadow?

10 feet post - 1.167 ft shadow

x feet tower - 119 feet shadow

Applying cross multiplication:

\(1.167x = 10*119\)

\(x = \frac{1190}{1.167}\)

\(x = 1020\)

The cellphone towers height is 1020 ft.

Answer:

Not parallelogram

Step-by-step explanation:

points A(-4, 1), B(1,3), C(8, -1) and D(4, -3).

The slope of a line can be found using the following formula:

Slope  \(m= = \frac{(y_2 - y_1) }{(x_2 - x_1)}\)

where (x1, y1) and (x2, y2) are the coordinates of two points on the line.

Using the formula above,

Side AB: Slope =\(\frac{3-1}{1-(-4)}=\frac{2}{5}\)

Side BC: Slope =\(\frac{-1-3}{8-1}=\frac{-4}{7}\)

Side CD: Slope =\(\frac{-3 - (-1)}{4 - 8}= \frac{1}{2}\)

Side DA: Slope =\(\frac{-3 - 1}{4 - (-4)}= \frac{-1}{4}\)

Since The slopes of opposite sides are equal,

It would take 21 weeks for the population to surpass 16,000.

The insect population P in a certain area fluctuates with the seasons and is estimated by the function P = 15,000 + 2500 sin(πt/52), where t is given in weeks.

For the population to surpass 16,000, we can set up the following equation:

15,000 + 2500 sin(πt/52) = 16,000

Subtracting 15,000 from both sides, we get:

2500 sin(πt/52) = 1000

Dividing both sides by 2500, we get:

sin(πt/52) = 0.4

We know that sin(πt/52) is positive when t is between 0 and 52 and between 104 and 156 since sine is positive in the first and second quadrants. Therefore, we can write:

πt/52 = sin⁻¹(0.4)

Multiplying both sides by 52/π, we get:

t = (52/π) sin⁻¹(0.4)

Using a calculator, we can evaluate sin⁻¹(0.4) to be approximately 0.4115 radians.

t = (52/π) (0.4115)

t = 21.02

Therefore, it would take 21 weeks for the population to surpass 16,000.

The aftertax cost of debt to Mojo Mining, given the company tax rate, and the maturity term of the bond, is F. 4. 58 %

First, find the yield on the bond. This yield can be found by the Rate function on Spreadsheet.

N = 18 years x 2 = 36 semi annual periods

PMT = 6.66% / 2 x 2, 000 = $ 66. 60

PV = 2, 120

FV = 2, 000

The spreadsheet would show a result of 3.05 % per semi annum. The annual rate is therefore:

= 3.05 % x 2

= 6.10 %

The aftertax cost of debt to Mojo Mining is therefore:

= 6.10 % x ( 1 - 25 % tax rate )

2nd answer option : 6^(13/4)

Step-by-step explanation:

what are we doing, when 2 equal base terms with exponents are multiplied ? we add the exponents !

this is like 3⁴×3³ = 3⁷

because

3×3×3×3 × 3×3×3 = 3×3×3×3×3×3×3 = 3⁷

it is that simple.

and that concept is also valid for any kind of number as exponent. even for fractions and so on.

so,

6^3 × 6^(1/4) = 6^(3 + 1/4) = 6^(12/4 + 1/4) = 6^(13/4)

Answer:

Victor has 18 trophies

Step-by-step explanation:

Let's set up "let statements"

Let d = Dean's trophies

Since Victor has 2 times as many trophies as Dean, we can set up a let statement for Victor like this...

Let 2d = Victor's trophies

Now we can set up an equation! Since we know Dean and Victor have 27 trophies altogether...our equation has to involve addition...

2d + d = 27

Combine like terms...(2d and d)

3d = 27

Divide 3 on both sides to isolate the variable "d"

3d ÷ 3 = d

27 ÷ 3 = 9

So...

d = 9

That means Dean has 9 trophies. But we are not done yet because we need to figure out how many trophies Victor has. Since Victor has 2 times the number of trophies as Dean we can do...

2 · 9 = 18

Therefore, Victor has 18 trophies!

Hope this helps :)

Vitor has 18 trophies and Dean has 9.
