The cycle time for trucks hauling concrete to a highway construction site is uniformly distributed over the interval 50 to 70 mi

IrinaK [193]

Answer:

2/3=0.6667

Step-by-step explanation:

Let X be the cycle time for trucks hauling concrete to a highway construction site

Given that X is U(50,70)

Hence pdf of X is

$f(x) = \frac{1}{20} ,50$

Let A be the event that cycle time is no more than 65 minutes and

B the event cycle time exceeds 55 minutes

Required probability

= the conditional probability that the cycle time is no more than 65 minutes if it is known that the cycle time exceeds 55 minutes

= P(A/B)

= $\frac{P(A\bigcapB)}{P(B)} \\=\frac{P(55$

The radius of the front wheel of Jordan's bike is 53cm.

sergeinik [125]

For this we start by putting km into cm
53.23 x 100,000 = 5,323,000
Now we divide by 53 to see the total number of revolutions
5,323,000 / 53 = 100,433.962 revolutiona
