Answer:
The probability that at least one internet user is more careful is 0.973
Step-by-step explanation:
We have been given that 70% of internet users are more careful about personal information when using a public wi-fi hotspot. Therefore, probability that a randomly chosen internet user is careful about the personal information would be 0.70.
We need to find the probability that among three randomly selected internet users, at least one is more careful. So, we can find the probability that none of the internet users is more careful and subtract that result from 1.
Therefore, the probability that at least one internet user is more careful is 0.973
Answer:
1. 21
2. 896
3. 20.9
Step-by-step explanation:
Use BODMAS/BIDMAS to solve.
Ur answer to ur division problem would be 87.2131147541
To answer this item, we formulate an equation that would relate the time, rate, and the final time.
A(t) = (Ao)(2)^(t/4)
We solve for the value of Ao by substituting the known values,
11 = (Ao)(2)^(50/4)
Ao = 1.89 x 10^-3
A quarter of 11 is 11/4. Using this value and the other known.
11/4 = (1.89 x 10^-3)(2)^(t/4)
The value of t from the equation is 42 minutes.
Answer:
The correct answer is A.
Step-by-step explanation:
From the picture you provided, you choose option A, f(x) = x^7 - x^3 - 3x^2 + 3 . Hope that helped :)
