In baseball, a player's batting average is the proportion of times that the player gets a hit out of

his total number of times at bat. Suppose we select a Major League Baseball player at random.

The random variable X= the player's batting average can be modeled by a normal distribution

with mean y = 0.261 and standard deviation o = 0.034. Use the 68–95-99.7 rule to approximate:

(a) The probability that a randomly selected player has a batting average greater than 0.329
(b) P(0.193 = X = 0.295)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

900 degrees

step-by-step explanation:

table 3 represents a direct variation function. : )

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
