Answer:

a)  Sunny     Cloudy

T = [  0.9        0.2  ]  Sunny

     [  0.1         0.8  ]  Cloudy

b) 0.72269

Step-by-step explanation:

Given that;

90% of all sunny days are followed by sunny days while 80% of cloudy days are followed by cloudy days;

i.e if today is sunny (90%), the next day is sunny so its 10% cloudy

and if today is cloudy (80%), the next day is cloudy so its 20% sunny

a)

Now let T be the transition probability matrix which is expressed as;

     Sunny     Cloudy

T = [  0.9        0.2  ]  Sunny

     [  0.1         0.8  ]  Cloudy

b)

If today is sunny, to find the probability that it will be sunny in 5 days from now = P^5.x where x = [ 1 ] sunny

                                     [ 0 ] cloudy

so

p^5X = P.P.P.P.P.x

P.x = [ 0.9    0.2 ] [ 1 ]  = [ 0.9 ]

        [ 0.1     0.8 ] [ 0 ]    [ 0.1 ]

(P^2).x = [ 0.9    0.2 ] [ 0.9 ]  = [ 0.83 ]

              [ 0.1     0.8 ] [ 0.1 ]      [ 0.17 ]

(P^3).x = p(p^2)x = [ 0.9    0.2 ] [ 0.83 ]  = [ 0.781 ]

                              [ 0.1     0.8 ] [ 0.17 ]      [ 0.219 ]

(P^4).x = p(p^3)x =  [ 0.9    0.2 ] [ 0.781 ]  = [ 0.7467 ]

                               [ 0.1     0.8 ] [ 0.219 ]    [ 0.2533 ]

(P^5).x = p(p^4)x =  [ 0.9    0.2 ] [ 0.7467 ]  = [ 0.72269 ]

                               [ 0.1     0.8 ] [ 0.2533 ]    [ 0.27731 ]

so (P^5).x = [ 0.72269 ] sunny

                   [ 0.27731 ]  cloudy

therefore the probability that it is sunny 5 days from is 0.72269

So, it says that he ordered 239,021 pounds of flour, but they delivered 451,202 pounds. You are going to subtract the delivered amount to the ordered amount.

451,202 - 239,021 = _________

_________ = The Extra Amount Delivered

451,202 - 239,021 = 212,181

That means, that they had delivered 212,181 extra pounds of flour.

Answer:

The answer is D.

Step-by-step explanation:

130 x 60 = 7,800 miles.  you don't need the extra information "5 days a week" to solve the problem.  

The equation is y = 26x and the number of miles he drives in 60 work days will be 1560 miles. Then the correct option is B.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Mr. Arnold drives 130 miles round trip to work 5 days a week.

Let x be the number of weeks and y be the total number of miles. Then the equation is given as,

y = 130x

y = 26x

Then the number of miles he drives in 60 work days will be

y = 26 (60)

y = 1560 miles

The equation is y = 26x and the number of miles he drives in 60 work days will be 1560 miles. Then the correct option is B.

Answer:

The probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition is 0.6049.

Step-by-step explanation:

We are given that it is believed that 3% of people actually have this predisposition. The test is 99% accurate if a person actually has a predisposition.

The test is 98% accurate if a person does not have a predisposition.

Let the probability that people actually have predisposition = P(PD) = 0.03

The probability that people do not have a predisposition = P(PD') = 1 - P(PD) = 1 - 0.03 = 0.97

Let A = event that the test is accurate

So, the probability that the test is accurate if a person actually has a predisposition = P(A/PD) = 0.99

The probability that the test is correct if a person actually has a predisposition = P(A/PD') = 1 - 0.98 = 0.02

Now,  the probability that a randomly selected person who tests positive for the predisposition by the test actually has the predisposition = P(PD/A)

We will use Bayes' theorem to calculate the above probability.

      P(PD/A) = [tex]\frac{P(PD) \times P(A/PD)}{P(PD) \times P(A/PD) + P(PD') \times P(A/PD')}[/tex]

                    = [tex]\frac{0.03 \times 0.99}{0.03 \times 0.99+0.97 \times 0.02}[/tex]

                    = [tex]\frac{0.0297}{0.0491}[/tex] = 0.6049.

Answer:

The probability of success if you switch to one of the remaining 4 doors is

[tex]P(K) =\frac{4}{9}[/tex]

Step-by-step explanation:

From the question we are told that

The number of doors is n = 9

Generally the probability that the car is in the door you choose is

[tex]P(C) = \frac{1}{9}[/tex]

Generally the probability that the car is in the rest of the doors is

[tex]P(C)' = \frac{8}{9}[/tex]

Given that Monty Hall opened the 4 goat doors then the probability that the car will be in the remaining 4 doors is mathematically evaluated as

[tex]P(K) = \frac{P(C)'}{2}[/tex]

=>      [tex]P(K) =  \frac{\frac{8}{9}}{2}[/tex]

=>      [tex]P(K) =\frac{4}{9}[/tex]

Thus the probability of success  if you switch to one of the remaining 4 doors is

    [tex]P(K) =\frac{4}{9}[/tex]

Answer:

Step-by-step explanation:

It's given in this question,

m∠2 = 41°, m∠5 = 94° and m∠10 = 109°

Since, ∠2 ≅ ∠9 [Alternate interior angles]

m∠2 = m∠9 = 41°

m∠8 + m∠9 + m∠10 = 180° [Sum of angles at a point of a line]

m∠8 + 41 + 109 = 180

m∠8 = 180 - 150

m∠8 = 30°

Since, m∠2 + m∠7 + m∠8 = 180° [Sum of interior angles of a triangle]

41 + m∠7 + 30 = 180

m∠7 = 180 - 71

m∠7 = 109°

m∠6 + m∠7 = 180° [linear pair of angles]

m∠6 + 109 = 180

m∠6 = 180 - 109

        = 71°

Since m∠5 + m∠4 = 180° [linear pair of angles]

m∠4 + 94 = 180

m∠4 = 180 - 94

m∠4 = 86°

Since, m∠4 + m∠3 + m∠9 = 180° [Sum of interior angles of a triangle]

86 + m∠3 + 41 = 180

m∠3 = 180 - 127

m∠3 = 53°

m∠1 + m∠2 + m∠3 = 180° [Angles on a point of a line]

m∠1 + 41 + 53 = 180

m∠1 = 180 - 94

m∠1 = 86°

From the information and diagram shown, the following are true;

Since m<2 is 41 degrees, hence m<9 is 41 degrees

Also, m<7 = m<10 (corresponding angles) =109 degreees

m<6 + m<7 = 180

m<6 = 180 - 109

m<6 = 71 degrees

m<4 + m<5 = 180

m<4 = 180 - 94

m<4 = 86 degrees

m<1 = m<4 (corresponding angles) = 86 degrees

m<8 + m<2 + m<7 = 180

m<8 + 41 + 109 = 180

m<8 = 180 - 150

m<8 = 30degrees

Answer:

y - 3x = 10

Step-by-step explanation:

The equation of a line in slope-intercept form is expressed as;

y - y0 = m(x-x0) where;

m is the slope of the unknown line

(x0, y0) is any point on the line.

First is to get the slope.

Given CD is formed by C(-5, 9) and D(7,5)

m  = y2-y1/x2-x1

m = 5-9/7+5

m = -4/12

m = -1/3

Since the line t is perpendicular to CD, the product of their slope will be -1.

mM = -1

M = -1/(-1/3)

M = 3

Substituting M = 3 and the midpoint of (7, 5) and (-5, 9 )into the formula above to get the equation of the line.

Midpoint of the line = (x1+x2/2, y1+y2/2)

M = (-7+5/2, 5+9/2)

M = (-2/2, 14/2)

M = (-1, 7)

Hence x0 = -1 and y0 = 7

Since y - y0 = m(x-x0

Equation becomes;

y-7 = 3(x+1)

y-7 = 3x+3

y-3x = 3+7

y - 3x = 10

Hence  a  linear equation for t in slope-intercept form is y-3x = 10

The Equation of perpendicular bisector t = [tex]y = 3x +4[/tex]

Given Line CD is formed by points  C(-5, 9) and D(7,5) hence it passes through these two points

Let the slope of this line is m

The Slope of line passing through C and D points is given by [tex]m[/tex]

So

[tex]m = (y_2-y_1) /(x_2-x_1)[/tex].....(1)

[tex]m = (5-9)/(7-(-5)) = -1/3.......(2)[/tex]

Given that [tex]t[/tex] is perpendicular bisector of CD

Let the slope of t  = [tex]m_t[/tex]

The product of  slopes of two perpendicular lines is -1

hence

[tex]m \times m_t = -1........(3)[/tex]

so we can from equation number (2) and (3) we can write

[tex]m_t[/tex] = 3

Also t is the perpendicular bisector and hence it passes through the mid point of line CD hence the mid point of CD

[tex]Midpoint \; of\; line \; joining\; two\; points = ((x_1+ x_2)/2, (y_1+y_2)/2) .......(4)[/tex]

From equation 4 we can write that

Mid point of CD =

[tex]((-5 +7)/2, ( 9 +5)/2 ) = (1,7)\\[/tex]

The equation of perpendicular bisector t  is given by equation (5)

[tex]y = 3x+c .........(5)[/tex]

also equation (5) is satisfied by the point (1,7)

hence we can write

[tex]7 = 3\times (1) +c \\ c = 4[/tex]

So  the Equation of perpendicular bisector t = [tex]y = 3x +4[/tex]

Answer:

The evidence suggests that more than 49% of community colleges students plan to vote in the next presidential election because the p-value is less than the significance level.

Step-by-step explanation:

Given that:

The null hypothesis is:

[tex]H_o : \mu = 49 \%[/tex] of community college students plan to vote in the next presidential election.

[tex]H_a : \mu > 49\%[/tex]  of community college students plan to vote in the next presidential election.

sample size = 650

sample proportion = 0.54

P-value =  0.01

Level of significance = 0.05

Decision Rule: To reject the null hypothesis if the p-value is lesser than the level of significance.

Conclusion: We reject the null hypothesis and conclude that the evidence suggests that more than 49% of community colleges students plan to vote in the next presidential election because the p-value is less than the significance level.

Answer:

There are a lot of things that can go wrong, especially when we have an error in a measure that we use a lot of times (each time, that error increases).

For example, you think that each meter of fence costs $5, but the actual price is $5.30, and you need 40 meters, then you think that you may need to pay:

40*$5 = $200

But they will actually charge you:

40*$5.30 = $212.

Now this is a small example, now let's go to medicine, suppose that you want to trait cancer with radiation in a pacient, if you do not use precise measures for the dosage of radiation or the measures of the tumor, you may cause a lot of damage in the patient. (And similar cases if you want to give some medication and the numbers that you use are not precise, you may overdose the patient)

So the use of precise numbers may be critical in a lot of scenarios.

============================================================

Explanation:

Solve each equation for y. In other words, get y by itself

Let's start with the first equation

-3x = 3 - y

-3x - 3 = -y

-y = -3x-3

y = 3x+3

Do the same for the second equation

-1+y = 3x-2

y = 3x-2+1

y = 3x-1

The two equations we got were

y = 3x+3

y = 3x-1

Both have the same slope (m = 3) but different y intercepts, so we have parallel lines here.

===================================================

Method 1

Add up the P(x) values from x = 0 to x = 5

0.000+0.004+0.033+0.132+0.297+0.356 = 0.822

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

Method 2

If A and B are complementary events, then P(A)+P(B) = 1 and that leads to P(B) = 1-P(A).

We can think of the events defined as follows

Either A or B must happen, but not both simultaneously

P(B) = 0.178 from the table

P(A) = 1-P(B)

P(A) = 1-0.178

P(A) = 0.822

which is a shortcut compared to method 1. It's a much faster shortcut the larger the table is.
