The Brewers spent $28 buying new toys for
their cats and dogs. Dog toys cost $6 each
and cat toys cost $5 each. How many of
each type of toy did the Brewers buy?
DOG TIMES
Zero says: First, take a guess at how many dog
toys they bought: 0
Now check to see if that answer works. Figure
out how much money it would cost to buy that
number of dog toys:
(your (price of
guess) 1 dog toy)
Subtract that amount from the total the
Brewers spent:
(total (price of
spent) dog toys)
Is what's left divisible by the price of one cat
toy? If so, divide to find the number of cat
toys they bought. If not, start again with a
new guess for the dog toys.

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.
