Answer:
12.4523 kg
Step-by-step explanation:
The variance is found by averaging the square of the deviance (how far a number is from the mean) of each number.
Since we found the average of the deviance, all we have to do now is square that, and divide by the number of subjects.
11.1590² = 124.5232 --> 124.5232/10 = 12.4523 kg
Answer:
I needed thisssss ! Thanks for the points and you too<3
Step-by-step explanation:
The answer to your question is because you multiply 3 . 8 = 24
The next thing to do is to use the addition property of equality, adding 56 to both sides of the equation:
6x = -9
Now you will use the division property of equality in order to completely isolate the variable, dividing both sides of the equation by 6:
x = -9 / 6
Simplify the fraction into its simplest form:
x = -3/2
