Evidence are simply facts to support a claim, while counterexamples are instances to show the contradictions in a claim
<em>The question is incomplete, as the required drop-down menus are missing. So, I will give a general explanation</em>
<em />
To show that a statement is true, you need evidence.
Take for instance:

The evidence that the above proof is true is by taking the <em>squares of both sides of </em>


However, a counterexample does not need a proof per se.
What a counterexample needs is just an instance or example, to show that:

An instance to prove that:
is false is:

Hence, the complete statement could be:
<em>In a direct proof, evidence is used to support a proof
. On the other hand, a counterexample is a single example that shows that a proof is false.</em>

Leslie did. If you multiply 4/5 by two, you get 8/10. 8/10 is greater than 7/10.
Answer:
20 yd²
Step-by-step explanation:
This problem is really easy once you break it down!
First, find the area of the triangle.

b = 5 + 3 = 8
h = 4 + 4 = 8


Now find the area of the square.



The last step is to subtract.
Area of triangle - area of rectangle =
32 - 12 = 20
20 yd²
Hope this helped! :)
Answer:
A = 40.0 (3 sig. fig)
C = 40
c = 15
Step-by-step explanation:
Using sin law,
sinA/15 = sin100/23
A = 40.0 (3 sig. fig)
Using angle sum of triange,
C = 180 - 40.0 - 100 = 40
Since angleA = angleC, by side equal opp angles, c = 15
Answer:
For this distribution of test scores, the standard deviation is equal to the square root of 9
D) 9
Step-by-step explanation:
We need to know the standard deviation formula:
(1)
Where:
S: Standard deviation
sum: Summation
x: Sample values
Am: Arithmetic mean
n:
Number of terms, in this case 3
Now, we need to know the arithmetic mean of the sample values: 2, 5 and 8

To know the standard deviation we need to have the summation of each term minus the arithmetic mean squared.
of each term:

Now, we can find the standard deviation:

The standard deviation is equal to the square root of 9
