2.)D-about 20
3.) A- about 48
4.) A- about 8
5.) C- 3 modes
What number is underlined on #1?
To identify and round a number to a specific place value, you need to locate the digit in that place and consider the digit to the right of it.
In the number 63.264, the underlined place is the thousandths place. To round the number to the thousandths place, you look at the digit in that place, which is 4. The digit to the right of it is 6. Since 6 is greater than or equal to 5, you round up the previous digit, which is 4, to 5.
Therefore, the rounded number to the thousandths place is 63.265.

To calculate the difference between the average annual rainfall in Miami and Indianapolis, subtract the rainfall in Indianapolis from the rainfall in Miami.
Miami: 61.93 inches
Indianapolis: 42.44 inches
Subtracting 42.44 from 61.93, you get approximately 19.49 inches.
Therefore, the answer is about 19.49 inches.

To estimate the total cost of 12 gallons of gas, multiply the cost of one gallon by the number of gallons.
Cost per gallon: $3.84
Number of gallons: 12
Multiply $3.84 by 12, which equals $46.08.
Therefore, the estimated total cost of 12 gallons of gas is about $46.08.

To estimate the number of textbooks included in the shipment, divide the total cost by the cost per textbook.
Total cost: $31.54
Cost per textbook: $3.79
Divide $31.54 by $3.79, which equals approximately 8.33.
Since you can't have a fraction of a textbook, round 8.33 to the nearest whole number, which is 8.
Therefore, the estimate is that about 8 textbooks were included in the shipment.

To determine the modes in a set of data, you need to identify the values that appear most frequently.
In the dataset 23, 34, 28, 34, 23, 28, 25, the modes are the values that appear the most. In this case, both 23 and 34 appear twice, which means there are two modes.
Therefore, the answer is 2 modes.
