Answer:
27 females are in the class
Step-by-step explanation:
Spilt 30 into 10 (30 divided by 10) and then you get 3. The number of males in the class is 3. Now subtract 30 from 3 and you get 27. Therefore, there are 27 females in the class.
You multiply vectors and scalar simply by multiplying each component by that scalar:
Finally, you sum two vectors by summing the correspondent coordinates:
Answer:
C. the largest value of that class
Step-by-step explanation:
Class limit is like an interval it has the lowest value and largest value and the all values between these lower and upper values lie within that class.
Hence, the Upper Class limit of a class is the largest value of that class.
Thus, only option C is correct.
Answer:
Let S be the total surface area. Then
h = ( S - 2 Pi r^2) / ( 2 Pi r)
Discussion:
Let S be the total surface area. Then
S = 2Pi r*h + 2 Pi r^2 => subtract 2 PI r^2 from both sides
S - 2 PI r^22 = 2 PI r*h => divide both sides by 2 PI r
h = ( S - 2 Pi r^2) / ( 2 Pi r)
