What is Mean, Medium and Mode?

Mean = finding the average. Add all the numbers together and divided by the amount of numbers there is

Medium= is finding the middle but first put into accending order

Mode= finding the most common number 

200

Find the Mean. 

1,7,2,6,3,3,5,2,8,9,10,2,1,7

1+7+2+6+3+3+5+2+8+9+10+2+1+7 = 66

66/14= 4.7

300

Fine the Medium.

1,6,3,5,2,4,4,6,5,2

1,2,2,3,4,4,5,5,6,6 = 4+4 = 8/2= 4

400

Find the Mode.

1,6,1,5,4,6,1,6,5,6

1,1,1,4,5,5,6,6,6,6 =6

500

Find the Mean, Medium and Mode.

12,23,34,12,23,65,43,43,12,22,23,65

12,12,12,22,23,23,23,34,43,43,65,65

Mean= 31.41

Medium= 23

Mode= 12 & 23

Interest

100

What is the formula of simple interest?

I = PRT divided by 100

200

What is the formula for compound interest? 

A= P(1+R/N)^nt

300

Find the Principal, Rate and the Time. 

Logan has $60,000 in a savings account. The interest rate is 5% per year and is not compounded. To the nearest cent, how much will he have in 1 year?

P= $60,000

R= 5% 

T = 1

400

Find the Principal, Rate, Time and Number of time interest is compounded. 

Bert opened a savings account and deposited $800.00 as principal. The account earns 6%interest, compounded annually. What is the balance after 2 years?

P= $800.00

R= 6%

T= 2 

N= 1 

500

Solve this problem. 

Hunter opened a savings account and deposited $300.00. The account earns 1% interest, compounded annually. If he wants to use the money to buy a new bicycle in 3 years, how much will he be able to spend on the bike?

A=P(1+r/n) ^nt

=300 (1+0.01/1) 1.3

=300 (1+0.01/1)³

=300(1+0.01)³

=300. 1.013

≈309.0903

≈$309.09
