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.
B is your answer. Hope this helps :)
If and only if it is a proportional relationship, the problem can be solved by creating a proportion of B1/T1=B2/T2. This can also be expressed as 4.5/3.5=5.4/x given the values. You must cross multiply, so 4.5x=3.5(5.4). This simplifies to x=4.2. So, the tail length would be 4.2 feet.
Hope this helps.
Answer:
3
Step-by-step explanation:
3*3*3*3=81
that's my answer
Step 1: multiply the numbers in front of the parentheses with each term inside the parentheses
15p - 9 = 5p - 5
Step 2: get like terms on the same side
10p = 4
Step 3: divide both sides by 10
p = 4/10
Step 4: simplify
p = 2/5
