What is the value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year

Answers

Answer:

The value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95

Step-by-step explanation:

Cost of building 20 years ago = 12000000

We are given that the cost depreciated at 9% per year

Formula : N(t)=N_0(1-r)^t

Where N(t)= Population after t years

N_0=Initial population=12000000

r= rate of depreciation=0.09

t = 20 years

Substitute the values in the formula:

N(t)=N_0(1-r)^t\nN(t)=12000000(1-0.09)^(20)

N(t)=1819738.95

Hence the value in millions of dollars of a downtown office building that cost 12 million dollars to build 20 years ago and depreciated at 9% per year is $1819738.95

A West Coast university statistics professor wishes to determine which surfboard brand delivers consistently longer rides, Channel Island or JS. He recruits two of his students who surf to assist in an experiment, and the student assigned to the Channel Island board is determined by coin flip. The three head out to the beach for an afternoon, with the professor holding up a sign at random times for the respective student to catch the next wave on his board, and the time spent on that wave is recorded. This is repeated until each student has ridden 10 waves. The brand of surfboard in this story is A) the explanatory variable. B) a parameter. C) stratified.D) the response variable. E) blinded.

Answers

Answer:

This is repeated until each student has ridden 10 waves. The brand of surfboard in this story is "the explanatory variable"

Step-by-step explanation:

the explanatory variable otherwise known as the the Independent variable.

in the scenario above the brand of surfboard is independent of the event because the brand doesn't matter in the experiment.

Walt made an extra $7000 last year from a part-time job. He invested part of the money at 10% and the rest at 7%. He made a total of $580 in interest. How much was invested at 7%?Select one:

Answers

We know that
Interest= PNR/ 100.
where P is the principal
R is the rate of Interest
 N is the no of years the sum has been invested for. 
Since N  is not given we assume that to be 1
Therefore we have 
10x /100 + (7000 -x)*7/100= 580

Multiplying both sides by 100
10x+(7000-x)*7 = 58000
simplifying
10x+ 49000 - 7x = 58000
3x = 58000-49000
3x = 9000
x= 3000
 therefore the sum of money invested at 7% = 7000 - 3000 = 4000

Final answer:

Using the given conditions, we establish two equations. The first from the total invested amount which of 7000 dollars and the second from the total interest of $580. We solve the system of equations to find the value of x, which signifies the amount invested at 10%. The rest of the money (7000 - x) was invested at 7%.

Explanation:

To solve this problem, we need to set up two equations based on the information given. These equations can be set up with the following assumptions: let us denote the amount of money invested at 10% as x and at 7% as 7000 - x.  

  1. First equation would be derived from the total amount invested which was $7000, so x + (7000 - x) equals to 7000.
  2. The second equation can be established from the total interest which was $580, so 0.10x + 0.07(7000 - x) equals to 580.

Solve the system of these two equations to find the value of x. The solution will yield the amount that was invested at 10%. The rest of the $7000, that is (7000 - x), was invested at 7%, which is what we're looking for.

If the vertices of triangle bcd are b(-3,3), c(3,5), and d(-1,0), what is the perimeter

distance formlula
D=\sqrt{(x2-x1)^(2)+(y2-y1)^(2)}

when you want to find the distance between points (x1,y1) and (x2,y2)


we nee
distace from
b to c
c to d
d to b


b to c is (-3,3) to (3,5)
D=\sqrt{(3-(-3))^(2)+(5-3)^(2)}=2√10

c to d is (3,5) to (-1,0)
D=\sqrt{(-1-3)^(2)+(0-5)^(2)}=√41

d to b is (-1,0) to (-3,3)
D=\sqrt{(-3-(-1))^(2)+(3-0)^(2)}=√13

add

b to c+c to d+d to b=2√10+√41+√13
