The mean is simply the average of the data set.
Mean = (3+4+6+7+9+9+11)/7 = 7
The median, on the other hand, is the middle data when you arrange them from least to greatest. The middle data here is 7.
Hence, initially, the mean and median are equal. In order to make the mean less than median, add another data point which makes it the lowest. For example, we can add 1 as the new data point. The mean would be:
Mean = (1+3+4+6+7+9+9+11)/8 = 6.25
The median is (6+7)/2 = 6.5
Therefore, you can add any number less than 3. For example, that could be 1.
The area is 275 units squared
Answer:
67% (rounded)
Step-by-step explanation:
Since there is 1-6,
There is 3,4,5,6 which is 4/6 chance being above 2.
2/3 = 66.6%
The initial amount is $650. The $400 is deposited in Account 1 with 3.5% annual simple interest. The $250 is deposited in Account 2 with 3.5% interest compounded monthly.
n = 2 years
Account 1: Simple Interest
F = P (1+rn)
= 400 (1 +(0.035*2))
= $428
Account 2: Compound Interest
F = P (1+i)^n
= 250 ( 1+0.035)^2
F = 267.81
Total money after 2 years = $428 + $267.81
T = $695.81
