The weight of a puppy was monitored for the first year of its life. The weight, in grams, of the puppy has a strong linear relationship with the number of months, x, since birth. The relationship can be modeled by the function f(x) = 1,200x + 400. What is the meaning of the y-intercept of the function?
A. The puppy weighed about 400 grams at birth
B. The puppy weighed about 1200 grams at birth
C. The weight of the puppy increases by about 400 grams per month
D. The weight of the puppy increases by about 1200 grams per month

Solve for x and select the correct answer

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
