The distance between major cracks in a highway follows an exponential distribution with a mean of 5 miles. (a) What is the probability that there are no major cracks in a 10-mile stretch of the highway

Step-by-step explanation:

From the question we are told that:

Exponential distribution mean

Distance

Generally the equation for Exponential distribution is mathematically given by

Therefore

Possion Y

Generally the equation for  The probability that there are no major cracks in a 10 mile stretch of the highway is mathematically given by

i think it is x = 1.2

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
