Answer: D. Getting at least 2 heads and Getting at least 2 tails
=========================================================
Explanation:
Choice A is not disjoint because "getting at least 1 tail" could have the sequence TTH. We see that we have two tails and exactly one head. So the events "getting exactly 1 head" and "Getting at least 1 tail" are possible to occur at the same time; therefore, they aren't disjoint events. Disjoint events are two events that cannot occur simultaneously. An example would be flipping heads and tails on the same coin at the same time.
Choice B is also not disjoint. We could have the sequence THT, which has at least one head and at least one tail. "At least" means that amount or more.
Choice C is also not disjoint. We could have the sequence HTT. This has exactly one head and at least two tails.
Choice D is the only thing left. It must be the answer. It is not possible to get 2 heads and 2 tails when Roger only flips the coin 3 times. He would need to flip the coin at least 4 times for this to happen. The portions "at least" don't even need to be considered. So this shows how choice D is disjoint.
Answer:
Step-by-step explanation:
4x + 7 = 3x + 14
x + 7 = 14
x = 7
4(7) + 7 + 3(7) + 14
28 + 7 + 21 + 14
35 + 35 = 70
Answer:
n = 62 + x
Step-by-step explanation:
From the problem given, it is clear that the orange has LESS calories than a nectarine. <em>HOW much less? "x" less.</em>
<em />
Also, orange has 62 calories. So, nectarine MUST HAVE 62 + x calories.
<em>If we let nectarine's calories be n, we can write:</em>
<em>n = 62 + x</em>

Answer: C) Never
If two integers are positive, the one closer to zero is <u> never </u> greater.
An example would be something like the integers 3 and 5. The value 3 is closer to zero, so it's not greater than 5. Stuff on the left is smaller than stuff on the right.
