6% of what number is 3?
6/100 * n = 3 ?
0.06 * n = 3 ?
n = 3 / (0.06) = 50 ; which is Answer choice: [D].

Step-by-step explanation:
Mean = Average : Sum of the data ÷ Number of data
So find the average number of lates per student
4 = Lates
30 (sum of frequencies) = Frequencies
So 4 ÷ 30 = 7.5
Therefore the answer is 7.5..
Answer:
FALSE
Step-by-step explanation:
In order to be consistent with the system of unit we should decide if we are going to work with the CGS system <em>(centimeter-gram-second)</em> or the MKS system <em>(meter-kilogram-second).
</em>
If we decide to work with the CGS system, the equation of motion would be
8,000x ′′ + 2x = 0; x(0) = 3, x ′ (0) = 0
since 1 Kg = 1,000 g
If we decide to work with the MKS system, the equation of motion would be
8x ′′ + 2x = 0; x(0) = 0.03, x ′ (0) = 0
given that 1 mt = 100 cm
If you have a fraction, take one number and put a different number on top or underneath, for example if you have 2 cats and 3 dogs, the ratio from cats to dogs would be 2:3 but if you did 2 cats to the total number of animals, you would add 2 and 3 and get 5, so the ratio would be 2:5.
