Madame Pickney has a rather extensive art collection and the overall value of her collection has been increasing each year. Three years ago, her collection was worth $500,000. Two years ago, the value of the collection was $550,000 and last year, the collection was valued at $605,000.Assume that the rate at which Madame Pickney’s art collection’s value increase remains the same as it has been for the last three years. The value of the art collection can be represented by a geometric sequence. The value of the collection three years ago is considered the first term in the sequence.
Write an explicit rule which can be used to determine the value of her art collection n years after that. Use this to determine the value of her collection 10 years after she started tracking its worth rounded to the nearest dollar.

Answer:

Value = 500000 × (1.1^n)

$1,296,871

Step-by-step explanation:

a = 500000

r = 550000 ÷ 500000 = 1.1

1st term is the initial year:

n years after that is the "n+1"th term

Value = 500000 × (1.1^n)

n = 10

500000(1.1¹⁰)

1,296,871.23005

What does mean, median, mode, and the other word mean

Answers

Mean: add all the numbers and divide by the number of numbers
    so if I had 1, 2, 2, 3, 4, I would add all of them together and get 12 then divide 12 by 5 because there are 5 numbers to get a mean of 2.4

Median: the middle number in a set
     in the set 1,  2,  2,  3,  4 the median would be 2 as it is in the exact middle of the set of numbers. ***Be careful! For this, the numbers HAVE to be in numerical order so it has to be 1, 2, 2, 3, 4   NOT something like 1, 2, 3, 2, 4

Mode: the number that appears the most in a set
     in the example 1, 2, 2, 3, 4  the mode is 2 because 2 appears more than the other numbers

Hope this helped!! 

so mean is when you add all the number you have and divide it how many number.

example: 1,4,5.6 if you add all the numbers the answer will be 16 and divide it 4 so you count how many number you have so 16 divide by 4 = 4.

the median is the one that are in the middle . to find it you have to place the number to least to greater and find the median.

Example:     4,6,10.5,3,1,8

so least to greater will be 1,3,4,5,6,8,10.  so when you count the median will be 5 because you count 1,3,4 and you count 6,8,10 so the middle is 5.

the mode is the number that occurs most often in the number like this

Example: 1,2,3,3,4,5, so the number that occurs most often is 3 .

Which statement correctly compares 11/20 an 5/9A:11/20<5/9
B:11/20>5/9
C:11/20=5/9

Answers

Answer:

(11)/(20)<(5)/(9)

A is correct.

Step-by-step explanation:

Given: (11)/(20)\text{ and }(5)/(9)

We need to compare the two fraction.

We can compare either greater , less or equal.

If we compare two fraction. First we make their denominator same.

Denominators are 20 and 9

We will find the LCD of 20 and 9

20 = 2 x 2 x 5

9 = 3 x 3

LCD = 2 x 2 x 3 x 3 x 5 = 180

\text{First Fraction}\rightarrow (11* 9)/(20* 9)\Rightarrow (99)/(180)

\text{Second Fraction}\rightarrow (5* 20)/(9* 20)\Rightarrow (100)/(180)

Now, we can see their denominator are same.

We will compare the numerator.

99<100

Thus,

(99)/(180)<(100)/(180)

(11)/(20)<(5)/(9)

Hence, (11)/(20)<(5)/(9) correct.

(11)/(20) =(11 * 9)/(20 * 9)=(99)/(180) \n \n(5)/(9)=(5 * 20)/(9 * 20)=(100)/(180) \n \n 99<100 \Rightarrow (99)/(180)<(100)/(180) \Rightarrow \boxed{(11)/(20) < (5)/(9)} \Leftarrow \hbox{answer A}
