If X is the hundredths digit in the decimal 0.1X and if Y is the thousandths digit in the decimal 0.02Y, where X and Y are nonzero digits, which of the following is closest to the greatest possible value of 0.1X0.02Y ?
Options:
4
5
6
9
10

(D) 9

Step-by-step explanation:

X is the hundredths digit in the decimal 0.1X and if Y is the thousandths digit in the decimal 0.02Y

Since we are looking for the greatest possible value of

A fraction becomes greater the bigger the numerator and the smaller the denominator.

We take the maximum possible value of X and the minimum possible value of Y.

Let X=9 and Y=1

0.19 X 0.021=9.05

From the options, the one closest is 9.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
