Answer:
(1) 9
(2)
(3) 6()
Step-by-step explanation:
From the question,
(1) ()²
Applyin the law of multiplication of surds
()² = (
(2) ()× (
) =
Also applying the the law of multiplication of surd
()×(
) = (
) ( This is an irational answer)
∴ ()×(
) =
(3) 2()×3(
)
Also applying the law of multiplication of surds i.e Multiply surds to surds and whole number to whole number
= 2×3×()×(
)
6×() = 6(
Answer:
The coefficient of variation for the weight and age are 5.9% and 10.6%.
Step-by-step explanation:
The coefficient of variation (CV) is well defined as the ratio of the standard deviation to the mean. It exhibits the degree of variation in association to the mean of the population.
The formula to compute the coefficient of variation is:
Here σ = standard deviation and µ = mean.
Compute the mean and standard deviations of the two data set in Excel using the following functions.
Mean=AVERAGE()
Standard deviation=STDEV.S()
Consider the Excel sheet attached.
The mean and standard deviation of weight are:
Mean = 202, Standard deviation = 11.87
And the mean and standard deviation of weight are:
Mean = 25.88, Standard deviation = 2.75
Compute the coefficient of variation for the weight as follows:
Compute the coefficient of variation for the age as follows:
Thus, the coefficient of variation for the weight and age are 5.9% and 10.6%.
