The answer is: 9There are 9 kinds of non-congruent isosceles triangles that can be formed <span>by connecting three of the dots in a 4 x 4 square array of dots</span>
The attached figure represents the explanation of the answer.

(3/4) / (1/12)
= (3/4) * 12
= 36/4
= 9
She can create 9
Answer:
Probability = 5/6
Step-by-step explanation:
- Between 22 and 29, 28 can only come once.
- There are a total of 6 numbers between 22 and 29 (23, 24, 25, 26, 27, 28).
<em>Step 1: Write the formula of probability</em>
Probability = number of possible outcomes/total number of outcomes
There is only one 28 so the chance of getting a 28 is 1/6.
Not getting a 28 would mean getting any one number from 23, 24, 25, 26 and 27.
<em>Step 2: Apply the probability formula</em>
Probability = number of possible outcomes/total number of outcomes
Probability of not getting 28 = 5/6
