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

Step-by-step explanation:
Given
Required
The intercepts
The x intercepts are where the graph crosses x axis.
From the attached plot, they are:
and 
These represent the start and end of the ball that is launched.
Hence, (d) is true
Answer:
1. An intuitive understanding of number, their magnitude, relationships, and how they are affected by operations.
2. The ability to work outside the traditionally taught algorithms.
3. The ability to perform mental mathematics
4. The ability to look at the world and make comparisons.
5. (In non-human animals) The ability to perceive changes in the number of things in a collection.
1 whole and 1/4 substracted to 1/3 can be written as:
1 1/4 - 1/3 =
= 5/4 - 1/3
We have to find a common denominator which is 12:
5/4 = 15/12
1/3 = 4/12
So now we just substract numerators:
15/12 - 4/12 = <u>11/12</u>
Answer:
D
Step-by-step explanation:
because when x = -2 on the graph the y is -2 (-2,-2)
when the x values is 0 the y value is 1 (0,1)
and when x is 1 the y value is 2. (1,2)
hope this helps. have a good day
