Five classmates want to know how many of the 2520 students in their school prefer pop music. They each randomly survey 60 students. The table shows the results. Favorite Type of Music Country Pop Rock Rap Shannon 14 20 15 11 Trey 12 23 14 11 Robert 13 18 17 12 Callie 15 20 14 11 Lani 15 19 13 13 Use the results from each classmate to make an inference about the number of students in the school who prefer pop music. Based on Shannon's results, the number is students. Based on Trey's results, the number is students. Based on Robert's results, the number is students. Based on Callie's results, the number is students. Based on Lani's results, the number is students. Question 2 Describe the variation of the five inferences. Which one would you use to describe the number of students at the school who prefer pop music? Explain. The greatest is students. The least is students. The median of the data is . The mode of the data is . So, use the inference of students to describe the number of students at the school who prefer pop music.

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?
