please let me know which ones i need to restudy and do thank you
number six is wrong.
Sure, let me explain how to solve the questions:
1. To find the square root of 25, you can either calculate it manually or use a calculator. The square root of 25 is indeed 5.
2. To find the median of a set of numbers, you need to arrange them in ascending order and then find the middle value. In the given set: 23, 27, 33, 68, 72, 77, 85, the middle value is 68. So, the median is 68.
3. To find the mean of a set of numbers, you need to sum all the numbers and then divide the sum by the total count of numbers. In the given set: 13, 15, 18, 18, 18, 19, 22, 26, 28, 33, the sum is 210. Dividing it by 10 (number of values) gives us a mean of 21.
4. To find the mode, you need to identify the number that appears most frequently in a set. In the given set: 15, 14, 10, 15, 16, the mode is 15 as it appears twice.
5. To find the amount budgeted for miscellaneous, you can simply calculate 10% of the total budget. In this case, 10% of $560,000 is $56,000.
6. To add the fractions -3/8 and 8/35, you need to find a common denominator, which in this case is the product of 8 and 35 (280). Converting the fractions to have the same denominator, the sum would be (-3 * 35 + 8 * 8) / 280, which simplifies to -13/35.
7. The absolute value of -14 is obtained by removing the negative sign, resulting in 14. So, the answer is 14.
8. Subtracting -7.1 from -(-8.3) is equivalent to adding 8.3 to 7.1, which gives us 1.2.
9. To multiply the numbers 7.6, 1, and -6, you simply multiply them together: 7.6 * 1 * -6 = -45.6.
10. Dividing 90 by 18 gives us 5.
11. To find the reciprocal of 1/3 * (9 - 4), first evaluate 9 - 4, which is 5. Then, take the reciprocal of 1/3 * 5, which is 3/5.
12. In the given expression -15 - (-12)/-18 - (-18), the denominator -18 - (-18) evaluates to 0. Division by 0 is undefined.
13. Integers are whole numbers without any fractional or decimal parts. In the given options, 705 and -780 are integers.
14. To arrange the given set of numbers in ascending order, you simply list them in increasing order: -13, -2, 3, 8, 13, 18, 25.
Regarding question number 6, could you let me know what the correct answer should be?
