A school has 75% student participation in a fall carnival. Determine which simulation below would model the probability of student participation?
A. Rolling a number cube, where rolling an odd number represents students who participate in the fall carnival

B. Spinning a spinner with the equal sections marked with the letters A-E, where spinning a vowel represents students who participate in the fall carnival.

C. Spinning a spinner with four equal sections, where spinning anything but 1 represents students who participate in the fall carnival

Using the given statements, state whether the conditional statement is true or false. p: 2 + 2 = 4 q: 7 + 1 = 7 is p q true or false?

What is the approximate value of  q  in the equation below? –1.613–1.5220.5853.079

The biologist has a second culture to examine. she knows that the population of the culture doubles every 15 minutes. after 1 hour and 15 minutes, her assistant found that 80,000 bacteria were present. a) what was the size of the initial population? b) predict the size of the culture at t=3 hours. what was the size of the population at 40 minutes? explain and justify your answers. c) create a graph of the population as a function of time. find an equation that can be used to predict the size of the population at any time t. d) examine the rate at which the bacteria culture is growing. how fast is the culture growing after 1 hour? after 1.5 hours? after 2 hours? use a time interval of h = 0.01 hours to estimate these rates. interpret these rates in terms of the context of the problem situation. how do these three rates compare?
