Ozuna is riding on a Ferris wheel at Santa’s. His height above the ground, in meters, is modeled by H (t) where t is the time in seconds. Create a trigonometric graph using cosine, where his minimum height is 10 meters and his maximum height is 30 meters. Use intervals of 10 for your time in seconds.

Use the x-intercept method to find all real solutions of the equation. -9x^3-7x^2-96x+36=3x^3+x^2-3x+8

For how answer my question this will be the last question can you answer in math subject

Apsychology student wishes to investigate differences in political opinions between business majors and political science majors at her college. she randomly selects 100 students from the 260 business majors and 100 students from the 180 political science majors. does this sampling plan result in a simple random sample? why or why not? no, because each group of 200 students in the sample does not have the same chance of being selected. yes, because each group of 200 students in the sample has the same chance of being selected. no, because each individual student does not have an equal chance of being selected. yes, because each individual student has the same chance of being selected.
