A nice physics problem.
But 16t 2 is inappropriately written; you meant x = 16t^2, where "^" represents exponentiation.
The appropriate formula applying to this situation includes a "t" term which is not present in yours. Start with this:
s = s_0 + v_0t + (1/2)a^t^2, where x_0 is the initial height above the ground and v_0 is the initial velocity. "a" represents acceleration an here is -32.2 ft/(sec^2).
Here's how we apply this formula:
0 ft = 64 ft + 0*t + (1/2)(-32.2 ft/(sec^2), or
0 ft = 64 ft - 16.1 ft/(sec^2)
You must solve this equation for time, t. It will be a positive quantity.
Answer:
A) Fill the blanks, Fail, 0.15, Success, 244, 0.61
B) 240 times
Step by-step explanation:
A) Void , 96, 0.24
Fail, 60, it should be 0.15 because 60/400
Success, 400 - 96- 60 or 244 and the relative frequency is 0.61.
B)
There is a total of 1000. If the relative frequency is 0.24, multiply 0.24 by 1000 to get the amount of times YOU would expect to be VOID.
Or in other words , 240 times
By proving it add all up
0.24 x 1000 + 0.76 x 1000 = 1000

Answer:
The last one
Step-by-step explanation:
So 2 * -5 = -10
ITS -10 BECAUSE WHEN MULTIPLYING A EGATIVE AND POSITIVE NUMBER THE ANSWER IS ALWAYS A HEGATIVE.
So the last one is the best answer.

Answer: D) 49.86
276.99 x .18 (or 18%) = 49.8582
