Answer: 4 and 7

Step-by-step explanation:

The LCM (least common multiple) of two numbers is the smallest number (different from zero) that is a multiple of both.

So, we need to find 2 numbers different from 28 that have 28 as a multiple and it has to be the least one, so this numbers must be smaller than 28.

If we look into all the numbers smaller than 28 that have 28 as a multiple we find: 2, 4, 7 and 14

The only 2 that have the LCM 28 are 4 and 7.

Tju [1.3M]

The correct answer is:

The equation has no solution; therefore, the system of equations has no solution.

Explanation:

When solving a system of equations, after we combine the equations, if we find that there is no solution, that means that there is no solution to the entire system of equations.

The first quartile of a data set is 72, and the third quartile is 92. Which of these values in the data set is an outlier ?

konstantin123 [22]

Answer: Option D

D. 41

Step-by-step explanation:

A value $x_i$ is considered an outlier if

$x_i> Q_3 + 1.5IQR$

$x_i$

Where

$Q_3$ is the third quartile

$Q_1$ is the first quartile

IQR is the interquartile range.

$IQR = Q_3-Q_1$

In this case:

$Q_3=92\\Q_1=72$

$IQR = 92-72 =20$

$Q_3 + 1.5IQR = 92 + 1.5*20 = 122$

$Q_1 - 1.5IQR=72-1.5*20=42$

Then the outlier values will be all those greater than 122 or less than 42

Therefore the answer is the option D.
