77.1% chance that all 3 orders are correct.
For three independent events to find the probability of each one occurring we multiply the probabilities together. .917*.917*.917 = .77109 or 77.1 percent chance of all three outcomes being favorable.

Answer for number 12
aalyn [17]

Answer:

12 a. 4605 feet 12 b. 1,459,063 square feet

Step-by-step explanation:

For the perimeter, we simply add the lengths of each of the 5 sides together (or multiply 5 times one side length).

P = 5(921)

P = 4605 feet

For the area, we will use composition...add the area of the triangle to the area of the trapezoid.

For the area of the triangle, the formula is

A=\frac{1}{2}bh.

Filling in our values gives us

A=\frac{1}{2}(1490)(541) and

A = 403,045 square feet.

Now for the trapezoid.  The formula for a trapezoid is

A=\frac{1}{2}(b_{1}+b_{2})(h)

where the b's represent the bases and the h represents the height.  Filling in our values gives us

A=\frac{1}{2}(921+1490)(876)

Work inside the parenthesis first:

A=\frac{1}{2}(2411)(876) and

A = 1,056,018

Now we add those together to get that area of the Pentagon is 1,459,063 square feet
