Answer:

The percentage (V/V) of liquid menthol in the ointment is 1.59%.    

Step-by-step explanation:

Given : A prescription for an ointment has 3.5 mL of liquid menthol in a total of 220 mL.

To find : Calculate the percentage (V/V) of liquid menthol in the ointment ?

Solution :

Volume of liquid menthol is V_m= 3.5\ mL

Total volume of ointment is V_t= 220\ mL

The V/V percentage is given by,

\frac{V}{V}\%=\frac{V_m}{V_t}\times 100

\frac{V}{V}\%=\frac{3.5}{220}\times 100

\frac{V}{V}\%=0.0159\times 100

\frac{V}{V}\%=1.59\%

Therefore, the percentage (V/V) of liquid menthol in the ointment is 1.59%.

A random sample of 2 measurements is taken from the following population of values: 0, 1, 3, 4, 7. What is the probability that
mafiozo [28]

Answer:

1/5

Step-by-step explanation:

Range as a measure of central tendency is the difference between the highest value and the lowest value in a given set of data.

Given the samples 0,1,3,4,7

Total number of samples is 5

The range is gotten by taking the difference of 2 samplesout of 5samples and this can be done in 5C2 ways.

5C2 = 5!/(5-2)!2!

= 5!/3!2!

= 5×4×3!/3!×2

= 10ways

The total outcome is therefore 10

To get the probability that the range is 4, we need to get the required outcome of getting range of 4 and this can only occur twice

The range can be gotten by taking the difference between 7 and 3, it can also be gotten by taking the difference between 4 and 0. Both differences will give us a total of 4

The expected outcome is therefore 2

the probability that the range of the sample is 4 = expected outcome/total outcome

= 2/10

= 1/5

What is the radius of a hemisphere with a volume of 6466 to the nearest tenth of a meter?
Alecsey [184]

Answer:

14.6m

Step-by-step explanation:

volume of a hemisphere = (2/3)πr3

Therefore r = Cube root of ( Volume * 3/2 * 1/ pi)

r = cube root ( 6466 * 3/2 * 1/ π)

r = 14.56

in the nearest tenth of a meter = 14.6 m
