An electronics store advertises that one lucky customer will be given a television at the store's 10th anniversary celebration. On the day of the celebration, 150 customers, of which 82 are less than 30 years old and 68 are 30 years old or more, complete a form to enter for the chance
to win the television. The manager of the store wants to select the winner by drawing a form out of a box, but the box can only hold
100 forms
Which method ensures both that the manager can use the box for the selection and that each customer has a fair chance of winning?

A Divide the forms into two lots based on age. Then, randomly select one of the lots and place it in the box. Randomly select
the winning customer's form out of the box

B Sort the forms alphabetically by last name. Then, place the first 100 forms into the box. Randomly select the winning
customer's form out of the box.

C Randomly divide the 150 forms into three equal-sized lots. Then, randomly select two of the lots and place them in the box.
Randomly select the winning customer's form out of the box.

D. Randomly divide the 150 forms into five equal-sized groups. Then randomly select 4 of the groups and place them in the
box. Randomly select the winning customer's form out of the box

Complete the worksheet. use 3.14 for π and round all decimals to the nearest hundredth. find the volume of the composite three-dimensional figure above. important terms are written in bold.1. the pyramid has a square base that is inscribed in the circular base of the cone. draw an image of the composite shape of the base. 2. if the side length of the square base is 8 units long, what is the diameter of the circular base of the cone from the picture in number 1? 3. now that the diameter has been calculated, what is the circular area of the cone? ignore the square base of the pyramid.? 4. what is the formula for volume of a cone? 5.to calculate the volume of the cone, the height is still needed. if the cone has a lateral surface with a length of 13 units, what is the height of the cone? 6.now find the volume of the cone. do not include the empty space for the pyramid. 7.. the side length of the square base of the pyramid is 8 units long. what is the base area of the pyramid? 8.what is the formula for the volume of a pyramid9. since the cone and the pyramid share the same vertex, what is the volume of the pyramid10.using the volume of the cone and the pyramid, find the volume of the composite shape. remember, the pyramid is empty. 11,. referring to the picture in number 1, what is the area of the composite base knowing that the square is empty? 12what is the formula to find the lateral surface area of a cone? (13find the lateral surface area of the cone14what is the lateral surface area shape of the pyramid? what is the formula for its area? 15to find the lateral surface area of the pyramid the length is still needed. calculate the lateral surface length of the pyramid. 16 now that the lateral surface length is known, what is the lateral surface area of the pyramid17. using the lateral surface areas of the cone and pyramid, along with the area of the composite base, what is the total surface area?
