The function f(t) = 33 sin (pi over 2t) − 20 models the temperature of a periodic chemical reaction where t represents time in h

disa [49]

Maximum is when pi / 2t = 1 so that's 33-20 = 13 degrees
minimum when pi/2t = -1 - that gives -33-20 = -53 degrees

A cable car starts off with n riders. The times between successive stops of the car are independent exponential random variables

nikitadnepr [17]

Answer:

The distribution is $\frac{\lambda^{n}e^{- \lambda t}t^{n - 1}}{(n - 1)!}$

Solution:

As per the question:

Total no. of riders = n

Now, suppose the $T_{i}$ is the time between the departure of the rider i - 1 and i from the cable car.

where

$T_{i}$ = independent exponential random variable whose rate is $\lambda$

The general form is given by:

$T_{i} = \lambda e^{- lambda}$

(a) Now, the time distribution of the last rider is given as the sum total of the time of each rider:

$S_{n} = T_{1} + T_{2} + ........ + T_{n}$

$S_{n} = \sum_{i}^{n} T_{n}$

Now, the sum of the exponential random variable with $\lambda$ with rate $\lambda$ is given by:

$S_{n} = f(t:n, \lamda) = \frac{\lambda^{n}e^{- \lambda t}t^{n - 1}}{(n - 1)!}$

Answer:

$m\angle y=35.69^o$

Step-by-step explanation:

The picture of the question in the attached figure

we know that

In the right triangle of the figure

$sin(y)=\frac{7}{12}$ ----> by SOH (opposite side divided by the hypotenuse)

using a calculator

$m\angle y=sin^{-1}(\frac{7}{12})=35.69^o$
