When commercial aircraft are inspected, wing cracks are reported as nonexistent, detectable, or critical. The history of a particular fleet indicates that 68% of the planes inspected have no wing cracks, 27% have detectable wing cracks, and 5% have critical wing cracks. Five planes are randomly selected. (Round your answers to three decimal places.) (a) Find the probability that one has a critical crack, two have detectable cracks, and two have no cracks. 0.051 (b) Find the probability that at least one plane has critical cracks.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

noncoplanar points are points that do not lie on the same line.
