Answer: 8 minutes to 28 minutes

Step-by-step explanation:

To include 95% of all employees, it will be 2 standard deviations from the mean. Two above and two below. Each is 5 min. So add 10 and subtract 10 from 18.

On the Gaussian Curve, about 68.3% are included within the first standard deviation above and below the mean. Then about 27.2% are added in the second standard deviation.

Answer:

a. The Venn diagram is explained in the attached word file.

0.61                                    

b. Not independent

Step-by-step explanation:

a. The hypothetical 1000 table for given situation is

                                          Adult(A)        Not Adult (not A)        Total

Travel outside (T)                 610                170                               780

Not Travel outside (not T) 110                110                               220

Total                                 720                280                               1000

P(Adult and travel outside)=P(A and T)=610/1000=0.61

b. Multiplication rule for independent events is

P(A and B)=P(A)*P(B)

P(A and T)=0.61

P(A)*P(T)=0.72*0.78=0.56

As P(A and T) is not equal to P(A)*P(T), so event "being an adult" and "travel outside" are not independent.

How many times larger is 5 × 106 than 5 × 102?<br><br>PLEASE HELP !
Ray Of Light [21]

Divide the largest one by the smallest one : for example, the number 4 is 42=2× larger than the number 2.

Indeed, If you multiply 2 by 42 you'll get 4.

Of course, if a number is n× larger than another, then this other is n× smaller than the first one.

It will of course work with floating point : 0.6×10.6≈0.6×1.6667=1 so 1 is ~1.6667 times larger than 0.6 while 0.6 is ~1.6667 smaller than 1.
