find all the points (x,6) that are 10 units from the point P (-17,-2)

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

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.

Answer:

Commutative property

5

Step-by-step explanation:

The identity used in equation (-2) + 6 + 1 = 1 + 6 + (-2) is commutative property.

Given,

To Identify the property used in this equation:
(-2) + 6 + 1 = 1 + 6 + (-2)
commutative property

In mathematics, it deals with numbers of operations according to the statements.

Commutative property

The commutative property procedure applies to addition and multiplication. The addition procedure says that a + b = b + a and the multiplication procedure states that a x b = b x a. These procedures are used to define the notion that when adding or multiplying, values can “commute”, or resettle, and the outcome will not change.

Given equation,
(-2) + 6 + 1 = 1 + 6 + (-2)
Which shows the resettlement of -2, which does not affect the outcome of the equation. This is commutative property.

Thus, the identity used in equation (-2) + 6 + 1 = 1 + 6 + (-2) is commutative property.

Step-by-step explanation:

In order to find another way to represent the fraction [tex]2 \frac{1}{4}[/tex], we need to find different ways to represent fractions as a whole. One way to write fractions are as decimals.

We know that 2 as a decimal is just 2. We can leave that be for now.

We also know that [tex]\frac{1}{4}[/tex] as a fraction will just be [tex]1 \div 4[/tex], which is 0.25. Therefore, combining 2 and 0.25 we get 2.25.

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:

y  =  − 2 x  +  8

Step-by-step explanation:

Find the value of  b  using the formula for the equation of a line.

    Use the formula for the equation of a line to find  b .

    y = m x + b

    Substitute the value of  m  into the equation.

    y = ( − 2 ) ⋅ x + b

    Substitute the value of  x  into the equation.

    y = ( − 2 ) ⋅ ( − 3 ) + b

    Substitute the value of  y  into the equation.

    14 = ( − 2 ) ⋅ ( − 3 ) + b

    Find the value of  b .

    Rewrite the equation

    ( − 2 ) ⋅ ( − 3 ) + b = 14 .

    Multiply  − 2  by  − 3

    6 + b = 14

    Subtract  6  from both sides of the equation.

    b = 14 − 6

    Subtract  6  from  14 .

     b  =  8

Now that the values of  

m  (slope) and  b  (y-intercept) are known, substitute them into  y = m x + b  to find the equation of the line.

y = − 2 x + 8

Answer:

the answer is only A (I think so...)

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

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.

Answer:

Yes

Step-by-step explanation:

Each inch equals 15 ft of the actual length. If the dimensions are 2in. by 1 1/2in. then you multiply each number by 15 to get the length in feet. You will get 30 by 25. There will be just enough room one one side, with plenty of room on the other.

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.

Carla can fill one glass in 4 seconds

Answer:

6 hours

Step-by-step explanation:

Total time it will take to complete the trip = Total time spent on riding + Time taken for lunch break.

Distance to be covered = 60 miles.

D = 60

Speed of riding = 15 miles per hour

S = 15

Thus time taken to cover a distance 60 miles by riding at a speed of 15 mph:

T=D/S=60/15

T= 4hours

They will spend 4 hours on riding and 2 hour of lunch break.

Hence total time taken to complete the trip = 4 + 2 = 6 hours.

It will take 6 hours to complete the trip.

The number of hours taken by riders to complete the trip is 6 hours.

Given that, distance = 60 mile, speed = 15 mph and lunch break = 2 hours.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

Using speed formula Speed=Distance/Time

Here, 15 = 60/Time

⇒ Time = 60/15

= 4 hours

Total time taken in the trip is 4+2 = 6 hours

Hence, the number of hours taken by riders to complete the trip is 6 hours.

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

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.

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 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.

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]

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
