Answer:
0.6 is the required probability.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 250
Probability of accessing internet at work = 37%

Probability of accessing internet at home = 44%

Probability of accessing internet at work and home = 21%

We have to evaluate the probability that a person in this sample accesses the internet at home or at work.

Thus, 0.6 is the probability that a person in this sample accesses the internet at home or at work

Answer:
1. 15.9
2. 12
3. 7.29
4. 20.8
5. 11.0
Step-by-step explanation:
We can use the Pythagorean Theorem to solve for x (a squared minus b squared equals c squared)
Example number 1 is solved by 17 squared - 6 squared equals 253
You do square root and get 15.90
Number 4 is you have to divide 24 by 2 because it is one of the sides
So it is 24 squared minus 12 squared
You find square root and get 20.80
