Here we know that Margie is standing on a bridge looking at the river. She throws a rock over the bridge with an initial velocity of 60 ft/sec. The height, h, of the rock at the rime t seconds after it was thrown can be modeled by the equation:

To calculate how long will it take for the rock to reach the surface of the water, we need to set
. So:

Given that time can't be negative, we just choose the positive value. Therefore, <em>it will take 4.70 seconds for the rock to reach the surface water.</em>

Step-by-step explanation:
You don't have any choices here, so we can just find the range of the answer. Then, you can select the correct answer.
The probability must be greater than 66.67%: P > 66.67% (or 2/3).
The chance of rain on Friday is 2/3. If it is more likely on Saturday, then it must be more than 2/3. 2/3 is about 66.67% percent.
