Answer:
8
Step-by-step explanation:
-2 x -2 = 4
4 - (-28 / 7 = -4)
4- -4 = 8

The correct answer is 4 ( 6x - 1 )
Answer:
It takes 1 second for the tape to reach the ground.
Equation to use:
As explain above, the initial position s 16 ft, there is no initial velocity, so , and the acceleration of gravity is 32 ft/s^2, and should be considered negative [as pointing down in the y-direction], so the equation simplifies to:
In order to find the tima it takes it to hit the ground, we simple solve the equation for t when y(t) = 0 (the tape has reached the ground (zero height in the y-direction):
We select the positive time (+1 second) which is what makes physical sense, since a negative value in time would mean time before the tape was dropped.
So the answer is: It takes 1 second for the tape to reach the ground.

Answer: Choice D</h3>
==================================
How I got this answer:
We can eliminate choices A and C because an outcome of "1" is not possible. This is because the smallest outcome allowed is 4, from adding 3 and 1. If we were just focused on drawing 1 card from the second stack, then an outcome of 1 is possible.
We can also eliminate choice B because the probabilities do not add to 1. Add up all the fractions shown in table B and you'll get the following:
1/15 + 2/15 + 1/5 + 4/15 + 1/5 + 2/15 + 1/15 = 1.067 approximately
All of the probabilities must add up to 1 for a probability distribution to be possible. This is why choice C is eliminated.
The only thing left is choice D
Add up the probabilities in choice D
1/15 + 2/15 + 1/5 + 1/5 + 1/5 + 2/15 + 1/15 = 1
we get the proper result of 1
Each probability in this table is found by dividing the number of times the outcome shows up out of 15. So for example, the outcome of "4" only happens one time out of 15 total, which is why 1/15 is the probability for this outcome. The fraction 1/5 is equivalent to 3/15.
