Answer:
x= 4
(not sure about a, sorry friend)
Step-by-step explanation:
Since the shape is congruent with the other sides it's the same.
First of all, it tells you that it eats 210 pounds of bamboo each week. A week has seven days so 210/7 which is 30. That is how much ONE panda eats per day. Because it is asking for two pandas, you multiply 30 by 2 and you get 60. So the answer is 60 pounds of a bamboo for two pandas per day

Answer:
6 for $37.50 has the same price
Step-by-step explanation:
The price per wand is found by dividing the price by the number of wands.
8 for $50 ⇒ $50/8 = $6.25 per wand
__
4 for $20 ⇒ $20/4 = $5.00 per wand <em>not the same</em>
6 for $37.50 ⇒ $37.50/6 = $6.25 per wand <em>is the same price</em>
10 for $65 ⇒ $65/10 = $6.50 per wand <em>not the same</em>
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.
