Step-by-step explanation: 7 / 2 = 3.5 :)
Answer:
Step-by-step explanation:
The equation of the form
has radius r.
Now your equation is
Hence its radius is 
Using the Empirical Rule, it is found that 95% of the employees will have a travel time within the following range:
B. 8 minutes to 28 minutes.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering that the mean time is 18 minutes and the standard deviation is 5 minutes, the the bounds of the 95% range are given by:
Hence option B is correct.

The answer is 56
Answer:
Option C
Step-by-step explanation:
A and B are said to be independent of
P(A intersection B) = P(A)*P(B).
Or if drawing is done with replacement, etc.
A) P(drawing a king) = 4/52 = 1/13
IF we replace again drawing a kind is the same 1/13
Hence independent
B) Coin flipping each toss is obviously independent of the other as prob of getting tail in a fair coin is 1/2 irrespective of the previous outcomes
C) Without replacement is not independent
Since first prob = 4/52 and second would be 3/51 not the same as before
D) Rolling a die is independent as getting a 2 in any throw is always the same.
C is answer
