Answer:
a) (2.64 -2/9 -0.35 +5/8)/4
b) perform the sum, then the division, then round as needed
Step-by-step explanation:
a) The average of a number of items is their sum, divided by the number of items. Here, we want the average of 4 changes, so we compute it as the sum of the changes divided by 4.
average change = (2.64 -2/9 -0.35 +5/8)/4

b) My calculator is capable of adding these numbers directly. For a result rounded to the nearest hundredth, it can be a good idea to represent the fractions using at least 3 decimal digits.
So, the steps would be ...
- convert fractions to their decimal equivalents, using 3 decimal digits
- add up the values
- divide by 4
- round to hundredths
Performing these steps, we get ...
average change = (2.64 -0.222 -0.35 +0.625)/4 = 2.693/4
average change ≈ 0.67 . . . degrees
The average daily temperature change of a city was 0.67 degrees.
Answer:
By rolling a 3, Joe looses 10 points.
Step-by-step explanation:
E: Event of rolling a regular die.
So, the number of possible outcomes = {1,2,3,4,5,6} = 6
Now, if the Even Number comes up, Score = + 5 times the number
If the odd number shows up: The score is - 10
Now, when the die is rolled, the outcome is 3.
Here, as 3 is NOT DIVISIBLE by 2, hence, 3 is a ODD NUMBER.
So, by the rules Joe will loose 10 points.
