<span>2x + 4y = 36
3x - 4y = -6
--------------add
5x = 30 
  x = 6

</span>2x+4y=36 
2(6)+4y=36 
12 + 4y = 36
4y = 24
  y = 6

using (4,7)

2(4) +4(7) = 8 +28 =36 True

3(4) - 4(7) = 12 -28 =-16 False (-16 is not -6)

 (4,7) is not a solution

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.

Enter your answer as a simplified fraction formatted like this: 42/53
expeople1 [14]

Answer:

\displaystyle -0.\overline{37}=-\frac{37}{99}

Step-by-step explanation:

<u>Convert a Repeating Decimal to a Fraction </u>

We need to convert the following decimal to a fraction:

-0.\overline{37}

Let's call x to the given number:

x=-0.\overline{37}

The number has two repeating (periodic) decimals, thus we multiply by 100:

100x=-37.\overline{37}

Note the decimals continue to repeat exactly like the original number.

Subtracting both expressións, the repeating decimals are simplified:

100x - x = -37

Operating:

99x=-37

Dividing by 99:

\displaystyle x=-\frac{37}{99}

The fraction cannot be simplified, thus:

\mathbf{\displaystyle -0.\overline{37}=-\frac{37}{99}}
