Find the mean and median of the past week’s temperatures.
During the week, the mean temperature was __ degrees.
During the week, the median temperature was __ degrees.

Answer 1

To find the mean and median of the past week's temperatures, we first list the temperatures:

- Sunday: 45 degrees
- Monday: 52 degrees
- Tuesday: 44 degrees
- Wednesday: 62 degrees
- Thursday: 55 degrees
- Friday: 49 degrees
- Saturday: 50 degrees

**Step 1: Calculate the Mean**

To find the mean, sum all the temperatures and then divide by the number of days.

Mean = (Sum of temperatures) / (Number of days)

Sum = 45 + 52 + 44 + 62 + 55 + 49 + 50
Sum = 45 + 52 = 97
Sum = 97 + 44 = 141
Sum = 141 + 62 = 203
Sum = 203 + 55 = 258
Sum = 258 + 49 = 307
Sum = 307 + 50 = 357

Mean = 357 / 7
Mean ≈ 51 degrees

**Step 2: Calculate the Median**

To find the median, we first list the temperatures in ascending order:

44, 45, 49, 50, 52, 55, 62

Since there are 7 temperatures (an odd number), the median is the middle number.

The middle number (4th number in the ordered list) is:

Median = 50 degrees

**Final Results:**
During the week, the mean temperature was approximately 51 degrees.
During the week, the median temperature was 50 degrees.
