Answer:
The real perimeter is:
And the area would be:
Step-by-step explanation:
For this case we know one side of a square given 6mm.
We can begin calculating the perimeter for the scale figure with this formula:
The area for this case is given by:
And we know that the drawing has a scale of 1 mm : 7 km and if we convert the perimeter to km we got:
And the area would be:
Answer:
Step-by-step explanation:
In order to calculate the volume of a triangular prism you need 2 things:
The triangles area and the prism's height.
Any prism's volume can be calculated by multiplying its base area with its height.
The Area of a triangle can be calculated in different ways.
The most used and "normal" way is:
(width * height) / 2
Another way is by using herons formula, which looks like this:
a, b, c = different sides of the triangle (length)
s = (a + b + c) / 2
a =
When you have the prism's base area () you just have to multiply:
(V = volume)

The probability that 2 out of 10 randomly selected shipments would be late is 0.19.
<h2>Given </h2>
A shipping company claims that 90% of its packages are delivered on time.
Jenny noticed that out of the last 10 packages shipped, 2 were late.
<h2>What is probability?</h2>The probability of success and failure remain the same throughout the trials.
The probability that 2 out of 10 randomly selected shipments would be late is given by;
Hence, the probability that 2 out of 10 randomly selected shipments would be late is 0.19.
