A random sample of 10 subjects have weights with a standard deviation of 11.6144 kg. What is the variance of their weights? Be sure to include the appropriate units with the result.

Variance=134.8943 kg

Step-by-step explanation:

The relationship between standard deviation and variance is that standard deviation is the square root of the variance.

So given the value of standard deviation to be 11.6144kg, the variance will be the square of the number.

Standard deviation= √variance

Standard deviation ²=√variance²

Standard deviation ² = variance

11.6144²= variance

134.8943

Variance=134.8943 kg

step-by-step explanation:

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)
