Answer:
The standard deviation of the weight, σ, is approximately 4.73 kg
Step-by-step explanation:
The weights of the six puppies are;
= 1, 2, 7, 7, 10, and 15
The number of puppies, n = 6
Therefore, we have;
The mean = μ = ∑x/n = (1 + 2 + 7 + 7 + 10 + 15)/6 = 7
The standard deviation, σ, is given as follows;

By substituting, we have;

Simplifying gives;


The standard deviation of the weight, σ ≈ 4.73 kg to two decimal places.
Answer:
4 years
Step-by-step explanation:
As 4*8 is 32
So 144+32 is 176
And 5*4=20
108-20 is 88
88*2 is 176
Answer:
0.025 meters large
Step-by-step explanation:
Just drag the decimal twice to the left since the 10 has a power of -2.
