aramuseum.org:

0.5488 = 54.88% probability that there space no defects in the perfect highway.

Step-by-step explanation:

In a Poisson distribution, the probability the X represents the number of successes the a random variable is given by the adhering to formula: In which

x is the variety of sucesses

e = 2.71828 is the Euler number is the typical in the offered interval.

The part of highway the your city is structure is 30 miles long.

The average is one defect per 50 miles. Because the highway is 30 miles, we have actually that: What is the probability the there are no (0) defects in the completed highway?

This is P(X = 0). So  0.5488 = 54.88% probability the there room no defects in the perfect highway.

An orange triangle warning authorize by the next of the road has an area the 266 square inches. The base of the authorize is 9 inch lon

aramuseum.org: the basic is 28 inches. The altitude is 9 inches

Step-by-step explanation:

Let h stand for the altitude the the sign.

Let b stand for the length if the basic of the sign.

The warning sign is triangle in shape.

The formula for determining the area of a triangle is expressed as

Area = 1/2bh

The basic of the authorize is 9 inches much longer than the altitude. This way that

b = h + 9

If the area the the authorize is 266 square inches, it way that

266 = 1/2 × h(h + 9)

266 × 2 = h(h + 9)

532 = h² + 9h

h² + 9h - 532 = 0

h² + 28h - 19h - 532 = 0

h(h + 28) - 19(h + 28) = 0

h(h + 28) - 19(h + 28) = 0

(h + 28)(h - 19) = 0

h = 19 or h = - 28

Since the elevation cannot it is in negative, then h = 19

b = h + 9 = 10 + 9

b = 28
