Rabies is a viral disease of mammals transmitted through the bite of a rabid animal. The virus infects the central nervous syste
lisabon 2012 [21]

Answer:

(a) The value of <em>x</em> is 0.30.

(b) The probability that a reported case of rabies is not a raccoon is 0.45.

(c) The probability that a reported case of rabies is either a bat or a fox is 0.15.

Step-by-step explanation:

Denote the events as follows:

<em>R</em> = reported case of rabies is a raccoon

<em>F</em> = reported case of rabies is a fox

<em>B</em> = reported case of rabies is a bat

<em>O</em> = reported case of rabies is a some other animal.

The data provided is:

P (R) = 0.55

P (F) = 0.11

P (B) = 0.04

P (O) = <em>x</em>.

(a)

A property of a probability distribution is that the sum of all individual properties is 1.

That is, \sum P(X)=1

Compute the value of <em>x</em> as follows:

\sum P(X)=1\\P(R)+P(F)+P(B)+P(O)=1\\0.55+0.11+0.04+x=1\\0.70+x=1\\x=1-0.70\\x=0.30

Thus, the value of <em>x</em> is 0.30.

(b)

The probability of the complement of an event is the probability of its not happening.

P(A^{c})=1-P(A)

Compute the probability that a reported case of rabies is not a raccoon as follows:

P(R^{c})=1-P(R)\\=1-0.55\\=0.45

Thus, the probability that a reported case of rabies is not a raccoon is 0.45.

(c)

Compute the probability that a reported case of rabies is either a bat or a fox as follows:

P(B\cup F)=P(B)+P(F)\\=0.11+0.04\\=0.15

Thus, the probability that a reported case of rabies is either a bat or a fox is 0.15.

The sum of two numbers is 75. The second number is<br> less than twice the first. Find the numbers.
Lera25 [3.4K]

Answer:

First number =26

Second number =49

Step-by-step explanation:

Question:

The sum of two numbers is 75. The second number is 3 less than twice the first. Find the numbers.

Given:

Sum of two numbers = 75

The second number is 3 less than twice the first.

To find the numbers.

Solution:

Let the first number be = x

Let second number be = y

The sum equation can be given as:

x+y=75

It is given that the second number is 3 less than twice the first.

This can be given as:

y=2x-3

Substituting the value of y in terms of x in the sum equation.

x+(2x-3)=75

Combining like terms.

3x-3=75

Adding 3 both sides.

3x-3+3=75+3

3x=78

Dividing both ides by 3.

\frac{3x}{3}=\frac{78}{3}

x=26

Substitution x=26 in the second equation to find y.

y=2(26)-3\\y=52-3\\\therefore y=49

Thus, first number =26 and second number =49.

(40 points) Math help please
kotegsom [21]

Answer:

x^6 +2x^5 -6x^4 +3x^2 +6x-18

Step-by-step explanation:

f(x) = x^2 +2x-6

g(x) =x^4 +3

We are going to multiply them

f(x) * g(x)=  (x^2 +2x-6)(x^4 +3)

First   (x^2 +2x-6)(x^4) = x^6 + 2x^5 -6x^4

Then x^2 +2x-6)(3)      =                              3x^2 +6x-18

                                      ----------------------------------------------

                                       x^6 +2x^5 -6x^4 +3x^2 +6x-18
