(no) eroy collected data on the number of hours that each staff member at eroy's electronics slept night. mary the manager slept for 9 hours, cam the cashier slept for 3 hours, teddy the truck driver slept for 7 hours, and sierra the security guard slept for 4 hours. find the median number of hours of sleep.

the Answer is 5.5

Step-by-step explanation:

lets sort it from least to greatest

3 4 7 9

then you Aline them

3 4 7 9

median is in the middle

3 4 7 9

the median is the mean of the two middle numbers

4+7

 2

so it equals 5.5

step-by-step explanation:

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
