Answer:
C is correct :)
Step-by-step explanation:
Answer:
36.75 feet below sea level
Step-by-step explanation:
Feet she descended in 25min
=0.5×25
=12.25
Therefore, the total feet she dived to
=12.25+24.25
=36.75
Answer:
20 miles with an error margin of ± 8 miles
Step-by-step explanation:
The margin of error of a result is the range in which an error can vary. To find the margin of error between both distances we have to
28-12 = 16, that is, the variation of the result has a range of 16 miles. So we will look for the midpoint of both distances
(X2-X1)/2+X1=(28-12)/2+12=16/2+12=8+12=20
So from this midpoint the value can vary between 8 points below and 8 points above that would cover the difference of 16 miles that we observed at the beginning
In this way, the correct answer is 20 miles with an error margin of ± 8 miles
Done
Answer:
Look below
Step-by-step explanation:
A.
8 + 9 + 10 = 27
9 + 10 + 11 = 30
10 + 11 + 12 = 33
B. Every answer is divisible by 3, every consecutive answer is also 3 more than the one before it.
C. Yes
19 + 20 + 21 = 60
D. No
8 is not divisible by 3. Also, the closest you can get is 6 (1 + 2 + 3) or 9 (2 + 3 + 4).
