A presidential candidate plans to begin her campaign by visiting the capitals in 44 of 4343 states. what is the probability that
QveST [7]

If the 4 states have to be in a specific order say ABCD, then the total number of different possible routes is:

 43P4 = 2,961,840

So the probability is:

1 / 2,961,840 = 3.38 x 10^-7

 

But if the 4 states can be in any order such as DBAC, ACBD etc, then the total number of different possible routes is:

 43C4 = 123,410

So the probability is:

1 / 123,410 = 8.1 x 10^-6

 

No I don’t think it is practical to list all the different possible routes to select the one that is best. We can simply use mathematical models to solve for that one.

A tourist takes a picture with a Moai statue on Easter Island. In the photograph, the Moai statue is approximately 4.54.54, poin
KengaRu [80]

Answer:

The of the tourist is 1.67 meters.

Step-by-step explanation:

Height of statue in photograph = 4.5 inches.

Height of tourist in photograph = 1.25 inches.

\dfrac{Statue}{Tourist}=\dfrac{4.5}{1.25}

Actual height of statue = 6.0 meters.

We need to find the the actual height of the tourist in meters.

Let x be the actual height of the tourist in meters.

\dfrac{Statue}{Tourist}=\dfrac{6.0}{x}

Ratio of height of statue and tourist are proportional.

\dfrac{4.5}{1.25}=\dfrac{6.0}{x}

3.6=\dfrac{6.0}{x}

3.6x=6.0

x=\dfrac{6.0}{3.6}

x\approx 1.67

Therefore, the of the tourist is 1.67 meters.
