<h3>
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.
Based on the calculations on the bisector of ST, the value of ST are equal to 38 and 30 respectively.
<h3>How to find the bisector of ST?</h3>
In order to determine the bisector of a line segment with two (2) endpoints, we would add each point together and divide by two (2).
For exercise 1, we have:
ST = SM + MT
ST = 19 + 19
ST = 38.
For exercise 2, we have:
First of all, we would determine the value of x as follows;
3x - 6 = x + 8
3x - x = 8 + 6
2x = 14
x = 14/2
x = 7.
ST = SM + MT
ST = 3x - 6 + x + 8
ST = 3(7) - 6 + 7 + 8
ST = 30.

Answer:
b
Step-by-step explanation:
(3,0 ), (0,-1) and 6, 1) all satisfy the given equation
Answer:
D. Because we would be interested in any difference between running on hard and soft surfaces, we should use a two-sided hypothesis test
Step-by-step explanation:
Hello!
When planning what kind of hypothesis to use, you have to take into account any other studies that were made about that topic so that you can decide the orientation you will give them.
Normally, when there is no other information available to give an orientation to your experiment, the first step to take is to make a two-tailed test, for example, μ₁=μ₂ vs. μ₁≠μ₂, this way you can test whether there is any difference between the two stands. Only after having experimental evidence that there is any difference between the treatments is there any sense into testing which one is better than the other.
I hope you have a SUPER day!
