Write an expression for the sequence of operations described below. add 3 and 9, then divide 8 by the result Type x if you want to use a multiplication sign. Type / if you want to use a division sign. Do not simplify any part of the expression.

Use this data in the problem below. follow the steps carefully. round to the nearest tenth. lot 3: week 1: 345 week 2: 340 week 3: 400 week 4: 325 step 1. jim enters the data and calculates the average or mean. step 2. jim calculates the deviation from the mean by subtracting the mean from each value. step 3. jim squares each deviation to remove negative signs. step 4. jim sums the squares of each deviation and divides by the count for the variance. step 5. jim takes the square root of the variance to find the standard deviation.

What is the slope of the line shown below?

What are “like terms”? why can we only add like terms?
