What is sin 0 when sec 0 = 5? 0 |(1,0) sin e = 2[?] [] Rationalize the denominator if necessary.

Komok [63]

Answer:

$Sin ~0 =\frac{2\sqrt{5} }{5}$

Step-by-step explanation:

$sec0=\sqrt{5}$

$cos~0=\frac{1}{sec0} =\frac{1}{\sqrt{5} }$

$sin ~0=\sqrt{1-cos^2~0}$

$=\sqrt{1-1/5}=\sqrt{5-1/5}$

$Sin~0=\sqrt{4/5} =2/\sqrt{5}*\sqrt{5}/\sqrt{5}$

$Sin~0=2\sqrt{5}/2=2\sqrt{5}/5$

Alladin's Amusement Park has a popular roller coaster ride. There are 2 trains. Each train has 7 cars. Each car holds 16 people.

Nataly [62]

Answer:

224

Step-by-step explanation:

Number of trains in the roller coaster = 2

Number cars in each train = 7

Total number of cars = Number of trains $\times$ Number of cars in each train = $7\times 2$ = 14

Number of people in each car = 16

Total number of people in 14 cars = Number of people in one car $\times$ Number of cars = 16 $\times$ 14 = 224

i.e.

Total number of people in the roller coaster in one run = 224

Number of runs made by each train in one hour = 10

Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.

224 $\times$ 10 = <em>2240</em>

The arrival of the city busses that trundle down my street is Poisson distributed. According to the published schedule, they arr

joja [24]

Answer:

There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given time interval.

What is the probability that exactly two such busses arrive within 3 minutes of each other

The mean is one bus each 10 minutes. So for 3 minutes, the mean is 3/10 = 0.3 buses. So we use $\mu = 0.3$

This probability is P(X = 2).

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 2) = \frac{e^{-0.3}*(0.3)^{2}}{(2)!} = 0.0333$

There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
