For the given cumulative frequency table, mean is 6.8

Cumulative frequency table shown below,

Value (X) Frequency (f) cumulative frequency X*f

2 0.05 0.05 0.1

4 0.35 0.4 1.4

6 0.05 0.45 0.3

8 0.25 0.70 2

10 0.3 1.00 3

Sum = 6.8

In cumulative frequency table , mean is the sum of table of, multiplication of value (X) and frequency (f).

Mean = ∑ X*f = 6.8

Therefore, mean $\mu=6.8$

Answer from: tinasidell1972

Use the cumulative frequencies to figure out what the individual frequencies would be. Check out the attached image for the table of x values with their corresponding frequency (f) values. Note how the partial sums add up to the cumulative frequency values.

Once you know the frequency f values, multiply each x and f pair together in each row. The column labeled "x*f" represents each product. Afterward, add up everything in the x*f column to get the final answer 6.8

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .

Carla was trying to decide what to do saturday evening. she has $100 available to spend for the evening. she has narrowed her choices down to these events: braves game, a concert of an artist she likes, or the georgia aquarium. admission to the braves game is $25, hot dogs cost $10, sodas cost $5. the concert costs $25 for admission, $20 for a souvernir t-shirt, and $10 for a soda. the georgia aquarium has the show of a lifetime with an all you can eat and drink that costs $100. carla does not want to take any driving chances, so in addition to the cost of the aquarium, she will also need to pay for her uber/lyft, which is $15 each way. which option should carla choose if she wants to spend the least? based on that choice, what then is carla's oppotunity cost? fully explain your answer in at least one paragraph.
