Atub of water is emptied at a rate of 3 gallons per minute. the equation y-12=36-1) models the amount of water
remaining, where x is time (in minutes) and y is the amount of water left in gallons) analyze the work shown below
to determine the initial amount of water.
1 solve for the variable
y - 12 = 3x - 1)
3-12-3x+3
yux+15
2 write the equation using function notation.
fo) = -3r15
the tub started with
gallons of water

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.
