You would need to give me the data to answer your question, but I can give you the definitions of the measures of variation!

The Mode is the number that repeats most often, (Ie. 1,2,2,3,4,5 the mode would be 2 because it appears twice-more than any other number)

The Mean is the average of the set of numbers(lets say we have 1,2,3,4,5. you would add them all up and divide by the number of figures: 1+2+3+4+5=15. 15 divided by 5[there are 5 numbers total] equals 3.)

The median is the middle number(Ie. 1,2,3,4,5 the median is 3 because it is in the middle.) If there are 2 middle numbers(Ie. 1,2,3,4,5,6) you take the two middle numbers(3 and 4) and find the mean of them(3+4=7, 7/2=3.5)

A townhouse in San Francisco was purchased for $80,000 in 1975. The appreciation of the building is modeled by the equation: A=8
jonny [76]

Answer:

In 1981 was the building worth double it’s value.

Step-by-step explanation:

Given : A townhouse in San Francisco was purchased for $80,000 in 1975. The appreciation of the building is modeled by the equation : A=80000(1.12)^t, where t represents time in years.

To find : In what year was the building worth double it’s value in 1975?

Solution :

The amount is $80,000.

The building worth double it’s value in 1975.

i.e. amount became A=2(80000).

Substitute in the model,

2(80000)=80000(1.12)^t

(1.12)^t=\frac{2(80000)}{80000}

(1.12)^t=2

Taking log both side,

t\log (1.12)=\log 2

t=\frac{\log 2}{\log (1.12)}

t=6.11

i.e. Approx in 6 years.

So, 1975+6=1981

Therefore, in 1981 was the building worth double it’s value.
