Complete question :
What is the mean change in the forecasted low temperatures? Remember, this can be found by averaging the values in the Difference column for the low temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between. Here are my temps Date High Low 9/13 84 75 9/12 96 75 9/11 93 78 9/10 91 77 9/9 92 76 9/8 93 77 9/7 91 77
Answer:
76.428 ; between 76 and 77
Step-by-step explanation:
Given the data :
Date ____ High _____Low
9/13_____ 84 _______75
9/12 ____ 96 _______75
9/11 _____ 93 _______78
9/10 _____ 91 _______77
9/9 ______92 ______ 76
9/8 ______ 93 ______ 77
9/7 _______91 ______ 77
Mean low temperature :
(75+75+78+77+76+77+77) / number of days
535 / 7
= 76.428
Hence, the mean is between ; 76 and 77
Ethan's mistakes in sorting the shapes into two groups are:
- Shape C does not belong to group 1 because it does not have square corners
- Shape F does not belong to group 2 because it does not have any square corners
<h3>How to spot the mistakes?</h3>
From the complete question (see attachment), the shapes are grouped using the following criteria:
- All the shapes in group 1 have 4 square corners
- All the shapes in group 2 have exactly 1 square corner
Using the above rules, Ethan's mistakes are: shapes C and F are placed in the wrong groups
