Which fractions is equivalent to 6/9?

2 answers:

4 0

Hey there!

The answer to your question is D because to get something equivalent you would have to multiply or divide the numerator and denominator by the same number. So I multiplied 6 and 9 by 2 and I got 12/18.

I hope this helps!

Consider 8x2 - 48x = -104.

ki77a [65]

Answer:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$

Step-by-step explanation:

<u>Quadratic Equation Solving</u>

We have the equation:

$8x^2-48x=-104$

Divide by 8:

$x^2-6x=-13$

Now complete the squares so the left side is a perfect square of a binomial:

$x^2-6x+9=-13+9=-4$

Factoring the perfect square:

$(x-3)^2=-4$

Taking the square root:

$x-3=\sqrt{-4}$

The square root of a negative number is an imaginary number:

$x-3=\pm 2\mathbf{i}$

Solving for x:

$x=3\pm 2\mathbf{i}$

The solutions are:

$3+ 2\mathbf{i}$

$3- 2\mathbf{i}$

What is the mean absolute deviation for the set of data below?<br><br> 2, 8, 10, 16

Evgesh-ka [11]

Solution: We are given below data:

$2, 8, 10, 16$

Now to find the mean deviation, we use the below formula:

$MD= \frac{\sum|X-\bar{X}|}{N}$

Where:

$\sum,$ represents the summation

X, represents the observation.

$\bar{X},$ represents the mean

N represents the number of observation.

$\bar{X}= \frac{\sum{X}}{N}= \frac{2+8+10+16}{4}=9$

$\sum |X-\bar{X}| = |2-9| + |8-9| +|10-9| +|16-9|=7+1+1+7=16$

Therefore, the mean deviation is:

$MD= \frac{16}{4}$

= 4
