You would add 9 to -6 and the answer to that is equal to X. X=3
Since the numbers are close together and you do not have any outliers, the mean would be the best measure of central tendency.
The value is
(5+6+7+8+9)/5 = 7
Answer:
B
Step-by-step explanation:
Answer:
a)The quantity (mg) of medication used to the nearest hundredths is 212.75mg
b) The quantity (mg) of the original medication left in the stock bottle to the nearest tenths is 287.3 mg.
Step-by-step explanation:
For question a) 125mg + 62.5mg +25.25mg= 212.75 mg to the nearest hundredths
b) The quantity left can be calculated by subtracting 212.75 from 500
500 - 212.75 = 287.25 to the nearest tenth is 287.3mg
V = PI x r^2 x H
471 = 3.14 x 5 x H
471 = 15.7 x h
h = 471 / 15.7 = 30 cm
314/ 15.7 = 20 cm
30-20 = 10 cm difference
