What is true of the coefficient of​ variation?

Mathematics
1 answer:
DedPeter [7]3 years ago
5 0

Answer:

A. The coefficient of variation is best used when comparing two data sets that use the same units of measure.

Step-by-step explanation:

The coefficient of variation (CV), is simply the standard deviation (itself a measure of variance or variation) relative to the mean of a distribution.

The coefficient of variation expresses a random variable’s variability in percentage terms. Therefore it is possible, through the coefficient of variation, to compare the variability of data across different samples, especially if the random variables are recorded in different units of measurement (such as cm, kg and minutes).

A coefficient of variation is always interpreted as a percentage. <u>Mathematical representation is:</u>

Coefficient\ of\ variation\ = \frac{Standard\ deviation}{Mean}\ \%

The coefficient of variation is best used when comparing two data sets that use the same units of measure.

Hence, the option (A) is the correct option.

a city bus completes its entire route 3 times each hour how long will it take the bus to complete the entire route 10 times
SOVA2 [1]

Answer: It will take 3.33 hours to complete it's entire route 10 times.

Step-by-step explanation: Time taken to complete it's entire route 3 times= 1 hour

∴Time taken to complete it's entire route 10times = 10/3

                                                                                      = 3.33 hours

A 48 inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece
Y_Kistochka [10]

Complete question :

A 48 inch board in to be cut into three pieces so that the second piece is twice as long as the first, and the third piece in 3 times as long as the first. If x represents the length of the first, find the lengths of all three

Answer:

Length of first piece = x = 8

Length of second = 2x = 8*2 = 16

Length of third = 3x = 8 * 3 = 24

Step-by-step explanation:

Let :

Length of first piece = x

Length of second = 2x

Length of third = 3x

The total lengtb of board = 48 inches

Hence,

First + second + third = 48

x + 2x + 3x = 48

6x = 48

x = 48 / 6

x = 8

Length of first piece = x = 8

Length of second = 2x = 8*2 = 16

Length of third = 3x = 8 * 3 = 24

the function h(x) is quadratic and h(3) = h(–10) = 0. which could represent h(x)? h(x) = x2 – 13x – 30 h(x) = x2 – 7x – 30 h(x)
Inga [223]
h(3)=h(-10)=0\\\\therefore\\\\h(x)=a(x-x_1)(x-x_2)\\\\h(x)=a(x-3)(x+10)=a(x^2+7x-30)\\\\Answer:\boxed{h(x)=x^2+7x-30}
