Triangle Numbers are generated by creating trianglesof progressively larger size. Example include pinswhen bowling or balls when

iris [78.8K]

for the first term:

n= 1 there is 1 item

n=2 there are 2+1 = 3 items

n = 3 there are 3+2+1 = 3+2 = 6 items

n = 4 there are 4+3+2+1 = 4+6 = 10 items

We are adding the "n" term each time

n = 5 10+5 = 15

n= 6 15+6 = 21

n = 7 21+7 = 28

n = 8 28+8 = 36

There would be 36 items in the 8th step

The distance between major cracks in a highway follows an exponential distribution with a mean of 5 miles. (a) What is the proba

Nonamiya [84]

Answer:

$P(Y=0) = 0.1353$

Step-by-step explanation:

From the question we are told that:

Exponential distribution mean $\=x = 5 miles$

Distance $d=10miles$

Generally the equation for Exponential distribution is mathematically given by

$\lambda=\frac{1}{E(X)}$

$\lambda=\frac{1}{5}$

Therefore

Possion Y

$10\lambda=10*(1/5)$

$10\lambda=2$

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

$P(Y=0) = \frac{e-2 (2)0}{0!}$

$P(Y=0) = e-2$

$P(Y=0) = 0.1353$
