Great Free Practice Problems (these problem is all "find the number" problems)

1. In a two-digit number, the tens digit is 5 less than the unit digit. The number itself is five more than three times the sum of its digits. What is the number?

2. The sum of digits of a two-digit number is 11. The reverse number is 9 greater than the original number. Find the reverse number.

3. The sum of the digits in a two-digit number is 14. If you reverse and double the original number, and then add the results to the original number, the sum is 222. Find the original number.

4. The unit digit of a two-digit number is four more than the then digit. If the number is doubled it will be q more than the reversed number. Find the number

5. In a three-digit number, the tens digit is the same as the hundreds digit. The ones digit of this number is equal to 1/3 of the sum of the other two digit. Find the number if the sum of all its digits is equal to 24

6. In a two-digit number, the units digit is six less than three times the tens digit. Four times the unit digit minus five times the tens digit equals 11. Find the digits.

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
