Answer:
x = -1
Step-by-step explanation:
<h2>
first divide 8 by 2, to get 3x-4 =x-6. then, add four on both sides to get 3x = x-6 + 4. to x's and number on different sides, you are now going to subtract 1x from both sides to get 2x = -6 + 4. solve to get 2x = -2. lastly, divide both sides by 2 do get <u>x = -1</u>

Step-by-step explanation:
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,
rjkz [21]
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.
