Answer:
0.623 is the probability that between 800 and 850 files get damaged.
Step-by-step explanation:
We are given the following information:
We treat virus can damage computer as a success.
P( virus can damage computer) = 35% = 0.35
The conditions for normal distribution are satisfied.
By normal approximation:

We have to evaluate probability that between 800 and 850 files get damaged.


0.623 is the probability that between 800 and 850 files get damaged.
B. 875
1/4 of 500 is 125. So 125 is how much they pay for day approx. 125 times the seven days will be 875.
Answer: -3.3%
By not knowing how i did it, means you will still not know how to do it next time you encounter a similar problem.
Knowing how to solve a problem is just as important or even more important than just knowing the solution.
Answer:
x=8.3 y=16.1
Step-by-step explanation:
87+12y+-7=180
29+9x+6=180
just add like terms then solve
