Answer:

No solution

Step-by-step explanation:

6X - 3Y = -9--------------(1)

- 2 X +Y= 5---------------(2)

from equation two,

Y = 5+2X------------------(3)

substitute equation (3) into equation (1)

6X-3(5+2X)= -9

opening bracket

6X-15-6X= -9

6X- 6X = -9+15

0 = 6

<h2>therefore the answer is no solution</h2>

STATISTICS The most familiar statistical measure is the arithmetic mean, or average. A second important statistical measure is t
NISA [10]

The absolute value equation for the scores within one standard deviation of the mean is:

|x - 20.9| = 5.3.

The minimum score that is within one standard deviation of the mean is of 15.6.

<h3>What is the absolute value function?</h3>

The absolute value function is defined by:

  • |x| = x, x >= 0.
  • |x| = x, x < 0.

It measures the distance of a point x to the origin of x = 0.

One standard deviation is of 5.3, while the mean is of 20.9, hence the absolute value equation for the scores within one standard deviation of the mean is:

|x - 20.9| = 5.3.

Which means that the minimum score is:

x - 20.9 = -5.3

x = 15.6.
