A production process is checked periodically by a quality control inspector. The inspector selects simple random samples of finished products and computes the sample mean product weights. The test results over a long period of time show that 30% of the values are over 19.5 pounds and another 30% are less than 16.5 pounds. The population variance of the products produced by this process is 83.21 What is the sample size used by the inspector for each sample? Show your work and write your answer on paper,

b. t=-25h+3

step-by-step explanation:

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
