A disk drive manufacturer sells storage devices with capacities of one terabyte, 500 gigabytes, and 100 gigabytes with probabili

ties 0.5, 0.3, and 0.2, respectively. The revenues associated with the sales of the storage devices in that year are estimated to be $50 million, $25 million, and $10 million, respectively. Let X denote the estimated revenue of storage devices during that year. Determine the probability mass function of X.

Answer:

Step-by-step explanation:

From the given information;

Revenue connected to 0.5 probability = 50 million

Revenue connected to 0.3 probability = 25 million

Revenue connected to 0.2 probability = 10 million

Suppose X is the variable that represents the revenue of storage devices in that year, Then: the probability mass function;

P(X =x) = \left\{\begin{array}{ccc}0.5 \ if \ X = 50 million \\0.3 \ if \  X = 25million \\0.2 \ if \  X = 10 million \end{array}\right

In a particular region of a national park, there are currently 330 deer, and the population is increasing at an annual rate of 1
Afina-wow [57]

Answer:

a) P(t) = 330 (1.11)^{t}

b)P(t) →population after t years.

   t →number of years.

c) Number of deer after five years = 556

Step-by-step explanation:

a) The population increasing at an annual rate of 11%, means the population is being multiplied by 1.11 each year.

So, we can use the formula

                             P(t) = P (1+\frac{r}{100} )^{t}

                             P(t) = 330 (1+\frac{11}{100} )^{t}

                             P(t) = 330 (1.11)^{t}

b) In this model

                        P(t) → population after t years

                          P → present population

                          r → annual increasing rate

c) Number of population after 5 years is,

                    P(5) = 330 (1.11)^{5}

                           = 556

 Number of deer after 5 years = 556

A triangle with vertices at A(0, 0), B(0, 4), and C(6, 0) is dilated to yield a triangle with vertices at A′(0, 0), B′(0, 10), a
Cerrena [4.2K]
K · ( 0, 0 ) = ( 0 , 0 )
k · ( 0 , 4 ) = ( 0 , 10 )
k · ( 6, 0 ) = ( 15, 0 )
k = 15/6 = 10/4 = 2.5
Answer: The scale of dilation is 2.5
