Answer:
14 classes
Step-by-step explanation:
Members:
They pay $4 each class, and $14 flat fee.
4x+14
Nonmembers:
They pay $5 each class
5x
Set the 2 expressions equal to each other
4x+14=5x
Subtract 4x from both sides
14=x
After 14 classes, the cost for members and nonmembers will be the same
Hope this helps! :)
Answer:
(c) n(n+1)/√2
Step-by-step explanation:
√2+√8+√18+√32+...
1√2+2√2+3√2+4√2+...+n√2
- First term= √2
- Common difference= √2
- Sₙ= n/2(2√2+(n-1)√2)= n/2(n√2+√2)=n(n+1)√2/2= n(n+1)/√2
Option (c) is correct
The answer is amortization
The standard deviation is the mean of the sum of the squared deviations between each observation and the mean. The measure of dispersion that is the easiest to compute is the interquartile range.
The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation implies that the values are dispersed over a wider range, a low standard deviation shows that the values tend to be close to the mean of the collection.
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
