Q2.

Mathematics
1 answer:
Nimfa-mama [501]3 years ago
7 0

Answer:

see below

Step-by-step explanation:

A = {8, 9, 10, 11, 12, 13, 14} and   B = {2, 4, 6, 8, 10, 12, 14, 16, 18}

----------------

(i) List down the elements of A’ and B’

{8, 9, 10, 11, 12, 13, 14, 2, 4, 6, 8, 10, 12, 14, 16, 18} - this is the elements of both sets

----------

(ii) Are sets A - B and B - A equal sets?

A-B= {9, 11, 13}

B-A= {2, 4, 6, 16, 18}

These are not equal as we can see

----------

(iii) Find and compare the sets (AUB)’ and A’∩B’ and share your observations

A∪B= {2, 4, 6, 8, 9, 10, 11, 12, 13, 14, 16, 18}- union included all elements of both sets

A∩B= {8, 10, 12, 14} - intersection only includes common elements

Need help dont know how to round <br><br>round this number to the nearest thousand? 0.7966347977​
tatyana61 [14]

Answer:

.797

Step-by-step explanation:

If your talking about a decimal number, you would say the <u>thousandth</u>. I know, weird, but don't blame me.

To round up, any number above 5 rounds up to the next value place, and any number below 5 rounds down to the last value place.

Ex:   1.3483838383

Since 8 is greater than 5, we could get rid of all the 83s and just round up to 1.35.

So the thousandths place in a decimal would be 0.79<u>6</u>66357977, so we just ask if the next number after the thousandths place is greater than 5. The place number after .796 is 6, so since it is greater than 5, we would round up to .797.

Our answer is .797.

Hope this helps!

Given: -1/2x &gt; 6. Choose the solution set.
vazorg [7]
The answer would be B. You multiply the 2 on both sides, getting 12 on the right. Then you divide by -1, and that switches the sign and makes 12 negative.
