please let me know which ones i need to restudy and do thank you

The only one I see a problem with is #6.

To add or subtract. you need a common denominator, in this case 8 x 35 = 280.

-105/280 + 64/280 = -41/280

I don't see how that reduces to -13/35.

I hope this helps. Thanks for asking.

It looks like your answers are mostly correct, but there are a few mistakes that I'll point out:

1. Correct!
2. Correct! The median is indeed 68.
3. Correct! The mean is indeed 21.
4. Incorrect. The mode is the value that appears most frequently. In the given set, the number 15 appears twice, while the other numbers appear once. So the mode is 15, not 17.
5. Correct! 10% of $560,000 is indeed $56,000.
6. Incorrect. To add or subtract fractions, you need a common denominator. In this case, the common denominator is 280. So -3/8 + 8/35 is (-105/280) + (64/280) = -41/280, not -13/35.
7. Correct! The absolute value of -14 is indeed 14.
8. Correct! -7.1 - (-8.3) is indeed 1.2.
9. Correct! (7.6) (1) (-6) is indeed -45.6.
10. Correct! 90 divided by 18 is indeed 5.
11. Correct! The reciprocal of 1/3(9-4) is indeed 3/5.
12. Undefined is the correct answer. The expression (-15-(-12))/(-18-(-18)) results in division by zero, which is undefined.
13. Correct! The numbers 705 and -780 are indeed integers.
14. Correct! The numbers in ascending order are -13, -2, 3, 8, 13, 18, 25.

Overall, you did a great job, but be careful with the mode (question 4) and adding fractions with a different denominator (question 6). Keep practicing and you'll improve!
