Answer:
122.0627kg
Step-by-step explanation:
The standard deviation is the square root of the variance.
That means:
From the question, the standard deviation of the weights of the 10 random subjects is 11.0482kg
We substitute to get:
We square both sides to get:
Therefore the variance is 122.0627kg
Answer:
Step-by-step explanation:
()/12
Divide the fraction by 12. This is because we need to split the sugar between 12 brownies, and to split something means to divide it. Use the switch, flip and multiply method.
I inserted an image on how to use this method.
Anyway, to use this method, we need 2 fractions, so instead of 12, we have to use .

Answer:
NO
Step-by-step explanation:
Look at the figure attached below, we know that the area of the cone is the sum of area of circle part and cone part of the figure.
to find the surface area of the cone, first measure the radius of the base and find the area of the circle part by formula . Then measure the side (slant height) length of the cone part and find the area of the cone part by the formula
.
Now the surface area of the cone is circumference of the circle plus area of the cone part.
i.e.
From the above discussion we concluded that surface area of the cone does not depend only on the circumference of the base but also we need side length of the cone part as well thus <em>all cones with a base circumference of 8 inches will </em><em>not </em><em>have the same surface area.</em>
