I would think the rgdp increased instead
Answer:
X=4.5
Explanation:
It is 4.5 because 1\2 of 4x is 2x. 1\2 of 2 is 1. Then you need to subtract 1 from 10. Then you need to divide 9 by 2.
Answer:
His average for 4 days is 2542.5 mg
Intake of 5th day has to be less than 1330 mg
Explanation:
In order to find the average we take the sum of intakes for 4 day ans then divide it by total number of day which is 4 days.
Average = (2150 + 3005 + 2700 + 2315) / 4
Average = 10170/4
Average = 2542.5 mg
To find the 5th day intake such that average is below 2300 mg:
Let 5th day intake = x
We apply the same method to find the average by taking the sum of intakes for 5 days and then dividing the total with 5 days now. This average has to be less than 2300 mg therefore we use the following method:
(2150 + 3005 + 2700 + 2315 + x ) / 5 < 2300
2300 = (10170 + x)/ 5 < 2300
10170 + x < 11500
x < 11500 - 10170
x < 1330 mg
I would choose answer 2, since that answer is based on a same size consisting of more than 1 person, making it applicable to statistic analysis and have an input in the observational study. The other questions ask for one data point, which isn't statistical

Man-to-man defense means that you have your assigned opposing player that you're supposed to guard and you run around following him and guarding him. In zone defense, you guard an area of the court, not the man, so you're not supposed to let anyone stay there. In the NBA, zone is forbidden because it slows down the game, making it more boring for fans, so they've developed a special type of a defense where they rotate all the time while still keeping some aspects of the zone.
