Test the hypotheses below with the given data. let alpha = 0.05. sample 1: average = 138.4, sigma = 6.71, sample size = 48 sample 2: average = 142.5, sigma = 8.92, sample size = 39 this is an example of

The data in the table represent the height of an object over time. which model best represents the data? height of an object time (seconds) height (feet) 05 1 50 2 70 3 48 quadratic, because the height of the object increases or decreases with a multiplicative rate of change quadratic, because the height increases and then decreases exponential, because the height of the object increases or decreases with a multiplicative rate of change exponential, because the height increases and then decreases

What does x = in this equation x+3+2x=x+5

Astuntman jumping off a 20-m-high building is modeled by the equation h=20-5t^2, where t is the same in seconds. a high-speed camera is ready to film him between 15m and 10m above the ground. for which interval of time should the camera film him?
