Answer:
105 feet or inches
Step-by-step explanation:
First we find the surface area of the base, (or the square.)
That is 25.
Next we find the areas of the triangle which is: ×height
The area of one triangle is 20, so we multiply it by 4.
That is 80.
Finally, we add both surface area to find the total surface area.
That is 80 + 25 = 105

Probabilities are used to determine the chances of Laura winning an activity
- The value of p is 1/12
- The expected score of the game is -1/6
- The probability that she has a total score of 5 after two rounds is 0
To calculate the value of p, we make use of the following probability formula
So, we have:
Collect like terms
Evaluate the sums, on the left-hand side
Subtract 11/12 from both sides
Hence, the value of p is 1/12
<h3>(b) How to calculate the expected score</h3>This is calculated using the following expected value formula
So, we have:
Evaluate the products
Simplify
Hence, the expected score of the game is -1/6
<h3>(c) The probability that she has a total score of 5 after two rounds</h3>From the table, we have:
For after two rounds, we make use of the following equation
Hence, the probability that she has a total score of 5 after two rounds is 0
