Answer:

4/5

Explanation:


Find the Greatest Common Factor (GCF) of 12 and 15,If it exists, and by dividing both the numerator and denominator by it, reduce our fraction. GCF = 3, and our simplified answer

12 ÷ 3 = 4
15 ÷ 3 = 5

So the answer is 4/5

Answer:

4/5

Step-by-step explanation:

To get the answer, find the GCF (greatest common factor) of the numerator and the denominator. Once you have the GCF, divide the 12 and 15 by that number. Here, the GCF is 3.

Answer:  The standard deviation was calculated incorrectly.

Step-by-step explanation:

  • The standard deviation measures the dispersion of the data values from the mean value.

It cannot be negative , because it is the square root of the variance .

We add all squared deviations from the data points away from the mean and (then divide it by the number of data values) to evaluate variance.

Since , any squared number cannot give a negative result.

⇒ Standard deviation cannot be negative.

⇒The standard deviation was calculated incorrectly.

Rest other things (given in options) can not be interpreted on the basis of given information.

Rex weighed 80 pounds a year ago. Now he weighs 92 pounds. What is the percent increase in his weight?
Anna11 [10]
So increased weight = 92-80 = 12

so ℅ = 12×100/80 = 15

so his weight is increased by 15℅ !!

Simplify

Answer: 4\sqrt{3}

Step-by-step explanation:

For this exercise it is important to remember the following:

i=\sqrt{-1} \\\\i^2=-1

Given the following expression:

-2i\sqrt{-12}

You can notice that the radicand (the number inside the square root) is negative. Therefore, in order to simplify the expression, you need to follow these steps:

1. Replace \sqrt{-1} with i and simplify:

(-2i)(i)\sqrt{12}=-2i^2\sqrt{12}=-2(-1)\sqrt{12}=2\sqrt{12}

2. Descompose 12 into its prime factors:

12=2*2*3=2^2*3

3. Substitute into the expression:

=2\sqrt{2^2*3}

4. Since \sqrt[n]{a^n}=a, you can simplify it:

=(2)(2)\sqrt{3}=4\sqrt{3}
