2 answers:
Answer:
The surface area is
Step-by-step explanation:
we know that
The tent is a triangular prism
see the attached figure to better understand the problem
The surface area of the triangular prism is equal to
where
B is the area of the triangular face
P is the perimeter of the triangular face
L is the length of the prism
<em>Find the area of the triangular face B</em>
<em>Find the perimeter of the triangular face P</em>
we have
substitute the values

For Independent Events, P(A) × P(B) = P(A∩B)
so we have, P(A∩B) = 0.4×0.1 = 0.04
P(A') = 1 - 0.4 = 0.6
This information can be represented on a Venn diagram as shown below
P(A'∪B) means the union of everything that is not A with everything that is B
P(A'∪B) = 0.06 + 0.54 + 0.04 = 0.64
so we have, P(A∩B) = 0.4×0.1 = 0.04
P(A') = 1 - 0.4 = 0.6

Answer:
1300 cm = 13 m
Step-by-step explanation:
We need to find meters in 1300 cm.
We know that,
1 m = 100 cm
1 cm = (1/100) m
It means,
Hence, there are 13 m in 1300 cm.
