Answer:

Step-by-step explanation:

2x - y = -2

3x - 3y = 15

-6x + 3y = 6

3x - 3y = 15

-3x = 21

x = -7

2(-7) - y = -2

-14 - y = -2

-y = 12

y = -12

(-7, -12)

Weights of golden retriever dogs are normally distributed. Samples of weights of golden retriever dogs, each of size nequals15

FrozenT [24]

Answer:

Step-by-step explanation:

If the population, in this case, weights of golden retriever dogs, follows a normal distribution, then the sample will too, even if the sample size is lower than 30. You only have to worry about the sample size being too small when a problem doesn't explicitly say the distribution from which the samples are drawn is normally distributed.
