A textbook costs 16.50 plus tax. After sales tax , the book costs $17.49 . What is the sale tax rate ?

5.99%

Step-by-step explanation:

5.99% × 16.50 = 0.98835

The temperatures (in degrees Fahrenheit) in Long Island recorded by the weather bureau over a week were 42, 49, 53, 55, 50, 47, and 52.

Data arranged in ascending order are : 42, 47, 49,50, 52,53,55

As mean can be find by dividing sum of all the observations divided by total number of observations.

Median gives the middle value of the Data. If number of observation is odd, median === 4 th observation= 50

If n is even, then Median = Mean of and[ +1 ] th term.

Mode is that data which appears maximum number of times.

Range = Maximum value in a data - Minimum value in the Data

Correct option is Median.
