Answer:
About 68% (is that an answer choice?)
Step-by-step explanation:
In a normal distribution (a bell curve), about 68 percent of the data is in the range between one standard deviation below the mean to one standard deviation above. If your mean is 27, and the standard deviation is 3, then one deviation below to one above would be 27 - 3 to 27 + 3, or 24 - 30.
Answer:
2 hours
Step-by-step explanation:
first tap= 3hours
therefore work done is = 1/3
second tap= 6hours
therefore work done = 1/6
so, 1/3+ 1/6
=2/6 + 1/6
=3/6
=1/2
=2/1 hours
=2 hours
Answer:
6 or 6.4
Step-by-step explanation:
Point 1
(xA,yA)= (9, 8)
Point
(xB,yB) = (5, 3)
Formula :
Distance between two points =
√(xB−xA)2+(yB−yA)2
Solution :
Distance between two points =
√(5−9)2+(3−8)2= √(−4)2+(−5)2= √16+25= √41 = 6.4031
Distance between points (9, 8) and (5, 3) is 6.4031
But you wanted it in a whole number so 6
Answer:
a
Step-by-step explanation:
Times oth sides by 100
100d=r(100-x)
divide both sides by (100-x)
