Answer:
The expression 35 - m is used to determine the number of gallons left in the tank after m minutes.Solution:Given that a tank containing 35 gallons of water is leaking at a rate of gallon per minute. Let "m" represent the number of minutes spent Number of gallons left in the tank = initial amount of water present – leaked amount of water
Number of gallons of water left = 35 gallons – number of minutes spent rate of leakage.
Number of gallons of water left = 35 gallons – m minutes 1 gallons per minute Hence, the required expression is 35 – m
Answer:
Population standard deviation
Step-by-step explanation:
Mean value = 4 + 12 + 6 + 9 + 6 + 11 = 48 / 6 = 8 mean
Standard deviation with numbers close together in random samples show the numbers would be close to their average mean and would never show spread of data in lower range numbers
Range = 12 - 4 = 8 does not determine the ''spread'' for measures such as temperatures it shows the mean also as unintended.
Criteria must include lowest and highest temperature to reflect 100 years and so population standard in lower set data would reflect a reliable calculation.
I think it would be the first one
Answer:
The two numbers are 21 and 9
Step-by-step explanation
(15+6) minus (15-6) gives a difference of 12
21- 9 = 12
The area is 32m², because the area if it were a complete rectangle is 48m², but when the small portion that is missing, 16m², is subtracted from that, you are left with 32.
