Answer:
Height = 8 cm
Step-by-step explanation:
Volume of cylinder = π×r²×h
288π = π × 36 × h
(Divide both sides by π)
288 = 36 × h
(Divide 288 by 36)
8 = h
The mean is 250.875.
Using this information, I can put the following into a calculator:
√(((250.875-195)²+(250.875-358)²+(250.875-201)²+(250.875-276)²+
(250.875-161)²+(250.875-301)²+(250.875-387)²+(250.875-128)²)÷8)
Which equals:
87.9878
This is the standard deviation of the MP3 players.
It would be 66 degrees because
this would equal 180 degrees
add the angles together:30+57+27=114
now subtract 180-114=66degrees
FINAL ANSWER:66degrees
Answer:
median = 2.8 m
Step-by-step explanation:
the median is the middle value of the data set in ascending order.
If there is no exact middle value then it is the average of the values either side of the middle.
the stem- leaf diagram shows the data in ascending order from 1.6 to 4.5
there are 10 data values so no exact middle value.
the median lies between 2.7 and 2.9
median = (2.7 + 2.9) ÷ 2 = 5.6 ÷ 2 = 2.8 m
