Answer:
The minimum number of faces a polyhedron can have is 4 faces.
Step-by-step explanation:
We know that a polyhedron is a shape surrounded by polygons. We also know that we need at least 3 sides to make a polygon. So, at the minimum a polyhedron can be made by using only triangular faces but in order to make a closed figure we need at least four triangular faces (which is a tetrahedron).
When the events are independent
P(A∪B) = P(A) + P(B) - P(A∩B) . . . . where P(A∩B) = P(A)·P(B)
Substituting the given numbers, you have
P(A∪B) = 0.3 + 0.9 - 0.3·0.9
P(A∪B) = 0.93
Answer: 110 pounds.
Step-by-step explanation:
1 kg = 2.2 pounds
Multiply both sides by 50
50 kg = 110 pounds
Answer:
A. 14,520 ft
Step-by-step explanation:
To start off this problem, we need to find how many miles James walks per hour. <u>To do that, lets divide 11 by 4.</u>
Next, since 5,280 feet are in a mile, we need to multiply 2.75 by 5,280:
James walked 14,520 ft. in one hour.
The y intercept is going to be 10x
