A block of ice melts 8oz every 5 minutes it began melting at 8:00am weighing 250 pounds at what specific time will it be complet
dimulka [17.4K]

Answer:

1:40 am the next day

Step-by-step explanation:

1 pound = 16 oz

The block of ice melts 1 pound or 16 oz in 10 minutes

10 x 250 = 2,500

It will take 2,500 minutes to melt completely.

2,500 divided by 60 = 41.66666 or 41 hours and 40 minutes              

60 minutes = 1 hour

1 day = 24 hours                    41.6666666 - 24 = 17.6666666

8 am + 17 hours and 40 minutes = 1:40 am the next day

Drug x, a drug that claims to treat male pattern scalp hair loss, was administered for 12 months to over 1800 men aged 18 to 41
egoroff_w [7]

The following statement

'In general, men who took drug x maintained or increased the number of visible scalp hairs; while scalp hairs counts in men who took the placebo continued to decrease'

can be referred as descriptive statistics, since we are saying that the msot of the men who took the drug gain scalp hairs while the contrary happened from those men who took placebo.

On the other hand, the statement

'drug x is effective in maintaining or increasing the amount of scalp hair in men'

Is a deduction you make, so it can be referred as inferential statistics
