Total letters in word 'COUNTING'=8

Number of vowels in word 'COUNTING'=3(O,U,I)

Total letter in word 'PRIME'=5

Number of consonants in word 'PRIME'=3(P,R,M)

We have to find the total number of outcomes.

Number of choice for O=3(P,R,M)

Number of choice for U=3(P,R,M)

Number of choice for i=3(P,R,M)

Number of outcomes of choosing a vowel from the word 'COUNTING' and a consonant from the word 'PRIME'=3+3+3

Answer:

(a)The probability that a person 65 or over and has a loan is 0.052.

(b)The probability that a person 65 or over and has a loan is 0.476

(c) The probability that a person is 65 or over and has a loan independent is 0.0952

Step-by-step explanation:

Conditional probability:

Let A and B any two event is connected to a given random experiment E. The conditional probability of the event A on the hypothesis that the event B is occurred, denoted by P(A|B), is defined as,

[tex]P(A|B)=\frac{P(A\cap B)}{P(B)}[/tex]

So, P(A∩B) = P(B).P(A|B)

Given that,

The age of 20% of population are 65 years or over.

26% of those whose age 65 years or more have loans.

53% of those whose age under 65 years have loans.

E= the person is 65 or more.

F= the person has loan.

P(E)= 20%=0.2

P(F|E)=26%=0.26

P(F|E')=53%=0.53

So,

P(E')=1-0.2=0.8

P(F'|E)= 1-0.26=0.74

P(F'|E')= 1-0.53=0.47

(a)

The probability that a person 65 or over and has a loan is

=P(E∩F)

=P(F|E).P(E)

=0.26×0.2

=0.052

(b)

A person who has a loan either 65 or more , or under 65.

P(F)= P(F∩E)+P(F∩E')

     =P(F∩E)+P(E').P(F|E')

     = 0.052+ (0.8).(0.53)

     =0.476

(c)

Independent event:

If A and B are two independent event,

Then,P(A∩B)=P(A).P(B)

The probability that a person is 65 or over and has a loan independent is

=P(E∩F)

=P(E).P(F)

=(0.2)×(0.476)

=0.0952  

The probability that a person is 65 or over and has a loan is 0.052, the probability that a person has a loan is 0.476, and the probability that a person is 65 or over and that the person has a loan independent is 0.0952.

Given :

Suppose 20% of the population are 65 or over, 26% of those 65 or over have loans, and 53% of those under 65 have loans.

Let A represent the person who is 65 or more and B represents the person who has a loan.

If (P(A) = 20% = 0.2) then (P(A') = 1 - 0.2 = 0.8)

If (P(B|A) = 26% = 0.26) then (P(B'|A) = 1 - 0.26 = 0.74)

If (P(B|A') = 53% = 0.53) then (P(B'|A') = 1 - 0.53 = 0.47)

a) The probability that a person is 65 or over and has a loan is:

[tex]\rm = P(A\cap B)[/tex]

[tex]\rm = P(B|A)\times P(A)[/tex]

[tex]=0.26\times 0.2[/tex]

= 0.052

b) The probability that a person has a loan is:

[tex]\rm P(B) = P(A\cap B)+P(B\cap A')[/tex]

        [tex]\rm = P(B \cap A)+P(A')\times P(B|A')[/tex]

        [tex]=0.52+0.8\times 0.53[/tex]

        = 0.476

c) The probability that a person is 65 or over and that the person has a loan independent is:

[tex]= \rm P(A\cap B)[/tex]

= P(A).P(B)

= (0.2)[tex]\times[/tex](0.476)

= 0.0952

Question;

Assumption:

Let us assume Brandon's running speed is = 18.30 and

Ruben's running speed is = 16.50 and

Answer:

The two equations that can represent the relationship between the meters and second for Brandon and Ruben are;

Brandon → Y₁ = 18.3·X₁ and

Ruben → Y₂ = 16.5·X₂

Step-by-step explanation:

The equation is of the form

Y = 17.45·X

That is Amy ran Y meters in X seconds

Therefore we have

[tex]17.45 = \frac{Y}{X}[/tex] or the value 17.45 is the running speed of Amy

Therefore, where the running speed of Brandon is 18.30  and the running speed of Ruben is 16.50  we have

Y meters ran by Brandon in X seconds given by

Y₁ = 18.3·X₁ and

For Ruben we have Y meters ran in X seconds given by

Y₂ = 16.5·X₂.

Answer:

Brandon : Y = BX, where B is the speed (positive integer) and X is the time in seconds.

Ruben : Y = RX, where R is the speed (positive integer) and X is the time in seconds.

Step-by-step explanation:

For Amy, the relationship between the distance run and the time taken is represented by the equation Y equals 17.45X, where she ran Y meters in X seconds.

Therefore we have,

Y = 17.45X

Y/X = 17.45 m/s, where m/s is meter per second.

Let us assume that the speed for Brandon is represented by B and that of Ruben is represented by R.

For Brandon, we obtain Y/X = B m/s

Y = BX

For Ruben, we obtain Y/X = R m/s

Y = RX

Answer:

a)   0.71

b)   0.9863

Step-by-step explanation:

a. Given the mean prices of a house is $403,000 and the standard deviation is $278,000

-The probability the probability that the selected house is valued at less than $500,000 is obtained by summing the frequencies of prices below $500,000:

[tex]P(X<500,000)=P(X=0)+P(X=500)\\\\=0.34+0.37\\\\=0.71[/tex]

Hence, the probability of a house price below $500,000 is 0.71

b. -Let X be the mean price of a randomly selected house.

-Since the sample size 40 is greater than 30, we assume normal distribution.

-The probability can therefore be calculated as follows:

[tex]P(X<x)=P(z<\frac{\bar X-\mu}{\sigma/\sqrt{n}})\\\\P(X<500,000)=P(z<\frac{500-403}{278/\sqrt{40}})\\\\=P(z<2.2068)\\\\\\=0.9863[/tex]

Thus, the probability  that the mean value of the 40 houses is less than $500,000 is 0.9863

Answer:

The weight of the brick is 60 ounce to the nearest ounce

Step-by-step explanation:

In this question, we are asked to calculate the weigh of Lou’s brick given the dimensions of the shape of the brick and the weight of the clay.

To answer this question quite aptly, we need to know exactly the volume of the rectangular prism given the dimensions we have in the question.

To calculate this volume , we simply use the measurements we have to get it.

mathematically the volume of a rectangular prism is simply V = w * h * l

where w , h and l are width, height and length respectively.

now let’s calculate!

V = 3.5 * 2.25 * 8 = 63 inches^3

Now we need to know what the brick weigh in ounce. We already have the weight of the clay. now this is equal to the volume of the brick divided by the weight of the clay.

Mathematically this is = 63/1.055 = 59.72 ounce which is 60 ounce to the nearest ounce

Answer:

60 ounce

Step-by-step explanations:

The volume of a rectangular prism is length multiplied by width and the height.

And if the width is 3.5 inches

Length is 8 inches

Height of 2.25 inches

V = 2.25 × 8 × 3.5

= 63 in³

And since the clay weighs 1.055 oz/in³,the total weight of the clay brick will be derived by dividing the volume of the brick by its weight per in³

63/1.055

= 59.7 and to the nearest whole number = 60 ounce

Step-by-step explanation:

so first you need to set up an equation,

lets do company Q first..

because the monthly fee is 3 bucks thats gonna be the number that goes hand in hand with x so lets put that down

Q - 3x

now we have to add our one time fee of 25 dollars

Q - 3x + 25 .. bam thats our first equation

lets do the same thing for our next company

W - x + 60

( because the fee is one dollar, theres no reason to put 1x, its not mathematically correct, so we just leave it as x )

so now we have to set up the equation together, and because we are trying to find when the two will meet and have an EQUAL cost we make them equal to each other

so

3x + 25 = x + 60

if you solve it...

2x + 25 = 60

2x + 35
