<h3>
Answer: {4, 14, 20}</h3>
Don't forget about the curly braces.
===========================================================
Explanation:
The upside down "U" symbol means "intersect". We're looking for where the two sets intersect or overlap. In other words, we're looking for all of the values are in both sets at the same time. It might help to draw out the Venn diagram (see the image attachment below).
The numbers 4, 14, and 20 are found in both set A and set B at the same time. Therefore, . Something like the value 7 is only found in set A, but not in set B. So we'll ignore that value. Similar things happen with 10 and 17 for set A, and also 1 and 9 for set B.
So that's why the answer you type in is {4, 14, 20}. The curly braces are there to tell the reader we're dealing with a set of values.
Answer:
The fourth option
Step-by-step explanation:
The answer is y=x +0.625x which is also 1.625x.
The value is :
34500 * 0.95^m
where m is how many months passed.
If 5% is lost, 95% remains.
Answer:
x>1/2
Step-by-step explanation:

x>1/2
The horizontal sums of the survey numbers are 200, so the numbers in the left chart are the survey values divided by 200.
The vertical sum in the first column is 188, so the first column of the right chart will be 76/188 and 112/188. Likewise, the vertical sum in the second column is 212, so the numbers will be 124/212 and 88/212.
Once you find the first number in each case, the second number is that value subtracted from 1, since the total of the two must be 1.
