Answer:
D
Step-by-step explanation:
the theoretical probability is a fancy term for an even amount of both, which would be 20 flips landing on H, and 20 landing on T. Since the question is asking what's the difference between the theoretical probability and the experimental results, you'd take 20(theoretical number of flips that land on H) and subtract 15 (experiment results for the amount of flips that land on H), and 20 - 15 = 5. Now that you know the difference is 5, you would divide 5 by 40 to find the answer. 5/40 = 1/8 when you simplify, making the answer D.
I added a screenshot of the question along with the given choices
<u><em>Answer:</em></u>F. 4 <span>÷ 5
<u><em>Explanation:</em></u>
We know that Amy has 5 yards of boarders and that she will use them to make 4 equal borders.
<u>This means that:</u>
she will divide 5 yards by 4 to know the length of each borderAmong the given choices, choices G, H and J show the division of 5 by 4 which is correct representation of the length
On the other hand. choice F shows the division of 4 by 5 which is an incorrect representation of the length.

A prime expression is a math term. It is a expression that can't be divided by anything other than a 1.
