What is the mean, median, and mode of these 7 numbers: 8,12,5,3,2,5,4
To solve for the mean, you would find the average of all the numbers: (8+12+5+3+5+4)/7= 5.57 To solve for the median, you would arrange the numbers from least to greatest and find the middle number. 2,3,4,5,5,8,12: Median = 5 To find the mode, you would find the number that occurs most often in the series. This would be 5.
You and your friend both have savings accounts. She has $15,000 in the bank with an annual interest rate of 3.25%. Your bank account has $12,000 with an annual interest rate of 5.3%. Who will have more money at the end of 2 years if no additional money is deposited?
You would first start solving for how much money your friend would have in two years. To do this, you would simply use the formula FV = PV*(1+r)^t: FV = 15000*(1+.0325)^2. This comes to $15,990.84. Then you would solve for how much money you would have in two years. You would use the same formula: FV = 12000*(1+.053)^2. This comes to $13,305.71. Therefore, your friend would have more money at the end of two years.
Solve the equation: 3x(-2+5)+5x=4
You would start by distributing the 3x to the numbers in the parenthesis. Example: -6x+15x+5x=4. Then, you would need to simplify the expression. 14x=4. Lastly, solve for x. x=.2857
