i know that this is 100% correcrt. i just took the quiz now
1.) To round 15.6571 to the underlined place value (5), we look at the digit to the right of 5, which is 7. Since 7 is greater than or equal to 5, we round up. Therefore, the rounded number is 15.66.
2.) To round 0.8914 to the underlined place value (1), we look at the digit to the right of 1, which is 4. Since 4 is less than 5, we round down. Therefore, the rounded number is 0.89.
3.) To round 7,022.56 to the underlined place value (3), we look at the digit to the right of 3, which is 2. Since 2 is less than 5, we round down. Therefore, the rounded number is 7,022.5.
4.) To round 345.678 to the underlined place value (6), we look at the digit to the right of 6, which is 8. Since 8 is greater than or equal to 5, we round up. Therefore, the rounded number is 345.68.
5.) To estimate the product of 3.7 and 8.06, we can round each number to the nearest whole number. 3.7 is close to 4, and 8.06 is close to 8. Multiplying 4 and 8 gives us 32. Therefore, the answer is about 32.
6.) To estimate the sum of 17.25 and 6.66, we can round each number to the nearest whole number. 17.25 is close to 17, and 6.66 is close to 7. Adding 17 and 7 gives us 24. Therefore, the answer is about 24.
7.) To estimate the difference of 8.7 and 9.6, we can round each number to the nearest whole number. 8.7 is close to 9, and 9.6 is close to 10. Subtracting 9 from 10 gives us -1. Therefore, the answer is about -1.
8.) To estimate the quotient of 11.7 divided by 1.8, we can round each number to the nearest whole number. 11.7 is close to 12, and 1.8 is close to 2. Dividing 12 by 2 gives us 6. Therefore, the answer is about 6.
9.) To find the mean, median, and mode of 47, 56, 58, and 63:
- The mean is the average of the numbers. Add the numbers together and divide by the total number of numbers. (47 + 56 + 58 + 63) / 4 = 224 / 4 = 56. The mean is 56.
- The median is the middle number when the numbers are arranged in order. Arrange the numbers in ascending order: 47, 56, 58, 63. The middle number is 56. The median is 56.
- The mode is the number(s) that appear most frequently. In this case, all the numbers appear only once, so there is no mode.
10.) To find how long it takes Jennifer to drive 459 miles at an average speed of 54 mi/h, we divide the total distance by the speed. 459 / 54 = 8.5 (rounded to one decimal place). Therefore, it takes Jennifer approximately 8.5 hours.
11.) The correct answer is 8.5 h (as explained above).
