Answer:

Image result for If y is a positive integer, for how many different values of y is, ∛144/a whole number brainly

2 different values

Therefore, "y" must be a factor of 144. Therefore, for 2 different values of "y" ( and ) is a whole number

example

We need the remember that:

Therefore, the radicand (In this case ) must be a perfect cube in order to get a whole number.

Remember that a perfect cube are the numbers that have exact cube roots. Therefore, "y" must be a factor of 144.

Now, we need to descompose 144 into its prime factors:

Then, the factors of 144 are:

Substitute values into to check:

Which one of the following is always true?a. The coefficient of variation measures variability in a positively skewed data set r

Tom [10]

Answer:

C. The coefficient of variation is a measure of relative dispersion that expresses the standard deviation as a percentage of the mean, for any data on a ratio scale and an interval scale

Step-by-step explanation:

Th Coefficient of Variance is a measure of dispersion that can be calculated using the formula:

$CV = \frac{\sigma_{x} }{\mu_{x} } * 100%$

Where $\sigma{x}$ is the Standard Deviation

and $\mu_{x}$ is the sample mean

From the formula written above, it is shown that the Coefficient of Variation expresses the Standard Deviation as a percentage of the mean.

Coefficient of variation can be used to compare positive as well as negative data on the ratio and interval scale, it is not only used for positive data.

The Interquartile Range is not a measure of central tendency, it is a measure of dispersion.

Please help with problem

siniylev [52]

5.
that is square-kite

square=AC^2=(AE+EC)^2=(9+15)^2=24^2=576

kite=1/2 times diagonals=1/2 times AC times BD=1/2 times 24 times (BE+ED)=12 times (7+7)=12 times 14=168

so the shaded area=576-168=408 square inches

6.
trapezoid=(base1+base2) times 1/2 times height

big one is base1=14, base2=25
height =10+12=22
area=(1/2)(14+24)(22)=(11)(38)=418

small one is base1=8
base2=25
height is 10
area=(1/2)(25+10)(10)=(5)(35)=175
so shaded area is 418-175=243 square cm

What is 5x+2y=-49 if -9<= x <=-7?

Arlecino [84]

I’m not quite sure I understand but if your saying that -9 =x and -7 =y then the answer would be -59 so the equation wouldn’t be true I hoped I helped :)
