For the given central angle, determine the distance traveled along the unit circle from the point (1,0). 57

aliina [53]

Answer: (a)- $0.99\ \text{units}$

Step-by-step explanation:

Given

Central angle is $57^{\circ}$

The radius of the unit circle is $1\ \text{unit}$

Arc length is given by

$\Rightarrow l=\dfrac{\theta}{360^{\circ}}\times 2\pi r$

Put the values

$\Rightarrow l=\dfrac{57}{360}\times 2\pi \cdot1\\\\\Rightarrow l=0.99\ \text{units}$

The time between calls made to Amazon's customer service is exponentially distributed with a mean of 10 minutes (taken between e

daser333 [38]

Answer:

The probability that the time between the next two calls is between 3 minutes and 7 minutes is 0.2442.

Step-by-step explanation:

Let <em>X</em> = time between calls made to Amazon's customer service.

The average time between calls is, <em>β</em> = 10 minutes.

The random variable <em>X</em> follows an Exponential distribution with parameter $\lambda=\frac{1}{\beta}=\frac{1}{10}=0.10$

The probability distribution function of <em>X</em> is:

$f_{X}(x)=\left \{ {{\lambda e^{-\lambda x};\ x>0}} \atop {0;\ otherwise}} \right.$

Compute the probability that the time between the next two calls is between 3 minutes and 7 minutes as follows:

$P(3$

Thus, the probability that the time between the next two calls is between 3 minutes and 7 minutes is 0.2442.

Hi,

$f(x)=\log(x)$ FALSE

$f(x)=\log(x-4)+1$ TRUE

→ $f(x)=\log(x-2)$

$f(x)=\log(x+2)$ FALSE

$f(x)=2log(x)$ TRUE
