Bret through a baseball up in the air. the following table represents the height f(t) in meters of the ball above the ground at time t seconds.
table:
time: 0-2-4-6
height: 3-4-3-0
which of the following is represented by the y intercept of f(t)?
a. the ball touches the ground after 6 seconds
b. the ball was thrown from a height of 3 meters
c. the ball reaches a maximum height of 4 meters
d. the ball reaches a maximum height in 2 seconds

The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.

15 and 14.7 are 1 apart, so 15 – 14.7 must be 1.
