B=3; C=16; and E=4096.
Using the information we have gives us

We know that:

We know that 2³ = 8, so B = 3.
To "undo" a square root, we square the number; 4²=16, so C = 16.
To "undo" a fourth root, we raise the answer to the fourth power; 8⁴ = 4096, so E = 4096.
7*4=28
7-4=3
so the width is 4 feet and the length is 7 feet
The answer is d because quotient means the outcome of a division between two numbers. So therefore it has to be a division equation, which is d.
I think it's the second one on the top, because the dotted one is actually inside the bigger one and you can get a clear representation of the sizes.
Answer: The variance of their weights = 9,752,155,009 kg.
Step-by-step explanation:
- The variance is the square of the standard deviation . it measures the spread between data values in a data set.
So if standard deviation of 10 subjects = 98753 kg
Then, variance = 
Hence, the variance of their weights = 9,752,155,009 kg.
