How many numbers are equal to the sum of two odd, one-digit numbers?

Seven numbers.

Step-by-step explanation:

Finding the numbers, which are equal to the sum of two odd number and it has to be single digit number.

Lets look into numbers which are odd and single digit.

1 =

∴ Sum of the number is

3 =

∴ Sum of above number is

5 =

∴ Sum of above number is

7=

∴ Sum of above number is

Now, accumlating numbers which are fullfiling the criteria, however, making sure no number should get repeated.

∴ Numbers are:

Hence, there are total 7 numbers, which  are equal to the sum of two odd, one-digit numbers.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
