Answer:
Step-by-step explanation:
i have no idea what to do
Here is a trick I always use:
Get rid of both zeros in100 for now
So just do 697*1 which is just 697
Now add the two zeros to your answer to get 69,700 which is the final answer
I hope this helps you
2x and 8x+40 complementary angles
their sum is 180
2x+8x+40=180
10x=140
x=14
Answer:
2 and 12 have same chance of occurring
3 and 11
4 and 10
5 and 9
6 and 8
Each pair has same occurrence chance
Step-by-step explanation:
Here, we are interested in calculating knowing the sums that have an equal chance of occurrence.
Firstly, we need a sample space. A sample space refers to the set of all possible results.
Please check attachment for this
From the sample space we have 36 results;
Let’s list the outcomes and the number of times they all appear;
1- 0
2- 1
3- 2
4-3
5-4
6-5
7- 6
8- 5
9-4
10-3
11- 2
12-1
From the above, we can see that;
2 and 12 have same chance
3 and 11
4 and 10
5 and 9
6 and 8
Answer:
I believe the answer is c.) x=4
Step-by-step explanation:
I saw this on a webpage:
The moment we see “x,” we can consider picking numbers. The key here is contemplating how complicated the number should be. Swim with the current – let the question tell you. A quick look at the answer choices reveals that x could be something simple. Ultimately, we’re just dividing this value by 2, 3, 4, 5, or 6.
Keeping this in mind, let’s think about the first line of the question. If there are 3 times as many adults as children, and we’re keeping things simple, we can say that there are 3 adults and 1 child, for a total of 4 people. So, x = 4.
Now, we know that among our 3 adults, there are twice as many women as men. So let’s say there are 2 women and 1 man. Easy enough. In sum, we have 2 women, 1 man, and 1 child at this picnic, and a total of 4 people. The question is how many men are there? There’s just 1! So now we plug x = 4 into the answers and keep going until we find x = 1. Clearly x/4 will work, so C is our answer. The key was to let the question dictate our approach rather than trying to impose an approach on the question.
