25% of 60 to 40% of 30<br> >, < or =

Travka [436]

You can reduce the percentages to fractions:

$25\% = \dfrac{25}{100} = \dfrac{1}{4}$

$40\% = \dfrac{40}{100} = \dfrac{2}{5}$

So, we have

$25\% \text{ of } 60 = \dfrac{1}{4}\cdot 60 = 15$

$40\% \text{ of } 30 = \dfrac{2}{5}\cdot 30 = 12$

Which statistic is a measure of how data are dispersed in a population and can be used to give context to larger data sets

OLEGan [10]

Answer:

standard deviation

Step-by-step explanation:

The standard deviation is defined as the measure of how spread out the numbers are in a given population. In other words, statistics refers to the amount of the dispersion or variation of a set of given values.

It is denoted by the Greek letter sigma, σ.

Thus the standard deviation is the measure of how dispersed the data are in the population which can be used to provide context to a larger data sets.

Mark incorrectly solved the inequality -4(5/2+3/2x) > 8. His work is shown. Which step shows an error based on the inequality

aliya0001 [1]

Answer : The incorrect step is, (A) step 1: -10 + 6x > 8

Step-by-step explanation :

The given expression is:

$-4(\frac{5}{2}+\frac{3}{2}x)>8$

Now solving this expression step by step.

First -4 distributed over parentheses.

$(-4\times \frac{5}{2})+(-4\times \frac{3}{2}x)>8$

Now solving bracket term, we get:

$-10-6x>8$

Now taking like terms together, we get:

$-6x>8+10$

$-6x>18$

$-x>3$

Now multiplying this expression by (-1), we get:

$x>-3$

Thus, the incorrect step is, (A) step 1: -10 + 6x > 8
