Answer:

For better understanding of the answer see the attached figure :

length of grid square on each axis on coordinate plane is 1 units

But here it is given to be 0.1 units.

So, in order to find the ordered pair (1.8 , -1.2) we need to first locate 1.8 on x-axis and -1.2 on y-axis

Now, as each axis one grid square equals 0.1 . So,we go 18 units on positive x -axis and mark point (1.8,0) and 12 units on negative y-axis and mark point (0,-1.2) and draw vertical and horizontal lines passing through these points respectively. And the point of intersection of these lines is our required point (1.8,-1.2)

Answer:

For finding the order pair (1.8,-1.2) in the coordinate plan he has to follow the following procedure,

Here, each axis one grid square equals 0.1.

In X -axis,

1 unit = 0.1

That is,  for finding the point 1.8 in x-axis,

He has to go 18 unit right side from the origin,

⇒ he get the point (1.8,0) in X-axis.

Now in y-axis,

1 unit = 0.1

Thus, finally for finding the point (1.8,-1.2), he has to go vertically downward to 12 unit from the point (1.8, 0)

Rabies is an often-fatal disease typically transmitted through the bite of an infected animal. The state of Florida has been rec
slega [8]

Answer:

a) 3.6

b) 1.897

c)0.0273

d) 0.9727

Step-by-step explanation:

Rabies has a rare occurrence and we can assume that events are independent. So, X the count of rabies cases reported in a given week is a Poisson random variable with μ=3.6.

a)

The mean of a Poisson random variable X is μ.

mean=E(X)=μ=3.6.

b)

The  standard deviation of a Poisson random variable X is √μ.

standard deviation=S.D(X)=√μ=√3.6=1.897.

c)

The probability for Poisson random variable X can be calculated as

P(X=x)=(e^-μ)(μ^x)/x!

where x=0,1,2,3,...

So,

P(no case of rabies)=P(X=0)=e^-3.6(3.6^0)/0!

P(no case of rabies)=P(X=0)=0.0273.

d)

P(at least one case of rabies)=P(X≥1)=1-P(X<1)=1-P(X=0)

P(at least one case of rabies)=1-0.0273=0.9727
