what are the answer choices
A veterinarian weighed a sample of 666 puppies. Here are each of their weights (in kilograms): 1, 2, 7, 7, 10, 151,2,7,7,10,151,

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:
The value of d of the given equation is 8.67
Step-by-step explanation:
Given equation as :
3 d + 16 = - 2 × ( 5 - 3 d )
Or, 3 d + 16 = - 10 + 6 d
Or, 16 + 10 = 6 d - 3 d
So , 26 = 3 d
∴ d =
= 8.67
Hence The value of d of the given equation is 8.67 Answer
Answer: Y= 86 X=94
What I did is, the angle minus 86 to give me 94
