SELECT ALL THE CORRECT ANSWERS A company is testing a new protein shake which they claim works better than their existing brand and improving an athlete's performance. funny selected 60 athletes from a training camp database, and divided them into three groups. The ages for the groups were 16 to 20 years, 21 to 25 years, and 26 to 30 years. In each group, half of the subjects were asked to use the new protein shake for month, and the other half were asked to use the company's existing brand for a month. The subjects were not informed about which protein shake they would be using. Which statements about the study are true? A. THE STUDY USES RANDOM SAMPLING B. THE STUDY USES BLOCKING ON THE BASIS OF GENDER C. THE STUDY USES BLOCKING TO REDUCE VARIABILITY FROM KNOWN FACTORS D. STUDY DOES NOT USE A CONTROL GROUP E. THE STUDY USES A REPEATED MEASURE DESIGN TO REDUCE VARIABILITY FROM UNKNOWN FACTORS

show us the graphs dude

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

i can't solve unless i know what the line is
