Tsunamis are dangerous! scientists use the formula s=\sqrt(9.8d) to calculate the speed (s) of the tsunami (in meters per second ) based on the depth (d) of the ocean (in meters). the 9.8 refers to the acceleration of the tsunami due to gravity, in meters per second squared. what is the depth of the ocean (to the nearest meter) if the tsunami is moving at a speed of 320 meters per second?

Drag the tiles to the table. the tiles can be used more than once. nd g(x) = 2x + 5 model a similar situation. find the values of f(x) and g(x) let's say that the functions f(x for the given values of x. fix)=5(4) * g(x) = 2x+5

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
