The table represents some points on the graph of a linear function. What is the slope of the line of this function?

Question asked:Jacob and Sarah are saving money to go on a trip. They need at least $1975 in order to go. Jacob mows lawns and Sarah walks dogs to raise money. Jacob charges $25 each time he mows a lawn and Sarah charges $15 each time she walks a dog. The number of dog walks that Sarah has scheduled is no more than four times the number of lawns Jacob has scheduled to mow. Sarah will walk at least 50 dogs.Write a set of constraints to model the problem, with x representing the number of lawns mowed and y representing the number of dogs walked.

My answer:

They need at least $1975. Jacob charges $25 each time he mows a lawn and Sarah charges $15 each time she walks a dog.

25x + 15y ≥ 1975

The number of dog walks that Sarah has scheduled is no more than four times the number of lawns Jacob has scheduled to mow.

y ≤ 4x

Sarah will walk at least 50 dogs.

y ≥ 50

b

[tex]\lambda  =0.04 [/tex]

c

[tex]P(X > 65 ) =0.0742  [/tex]  

Step-by-step explanation:

From the question we are told that

  The  number of success is  n =  5

   The time duration is  N  =  125 minutes

Generally the mean of the random variable is mathematically represented as

       [tex]\mu  =  \frac{N}{n}[/tex]

=>    [tex]\mu  =  \frac{125}{5}[/tex]

=>    [tex]\mu  =  25 [/tex]

Generally the rate parameter is mathematically represented as

      [tex]\lambda  =  \frac{1}{\mu}[/tex]

=>   [tex]\lambda  =  \frac{1}{25}[/tex]

=>   [tex]\lambda  =0.04 [/tex]

Generally the cumulative distribution function for exponential distribution function is  

   [tex]F(x) = \left \{0 \ \ \ \ \ \  x \le  0}} \atop {1 -e^{-\lambda t }\   x>0}} \right.[/tex]

Generally the probability that the time to success will be more than 63 minutes is mathematically represented as

 [tex]P(X > 65 ) =  1 - P(X \le 65)[/tex]

Here

    [tex]P(X \le 65) =  1 -e^{-65 *  \lambda }[/tex]  

=>       [tex]P(X \le 65) =  1 -e^{-65 *  0.04 }[/tex]    

=>       [tex]P(X \le 65) = 0.92573[/tex]    

So

     [tex]P(X > 65 ) =  1 - 0.92573 [/tex]  

     [tex]P(X > 65 ) =0.0742  [/tex]

a) The probability that the computer will be fixed by either A or B is 58%.

b) The probability that it was fixed by B is 57.14%

Given data:

a)

To find the probability that the computer will be fixed by either A or B, we can use the principle of addition for probabilities.

The probability that A can fix the computer is 30% or 0.30, and the probability that B can fix the computer if A cannot is 40% or 0.40.

Therefore, the probability that either A or B can fix the computer is the sum of these probabilities:

P(A or B) = P(A) + P(B if A cannot) = 0.30 + (0.70 * 0.40) = 0.30 + 0.28 = 0.58

Therefore, there is a 58% probability that the computer will be fixed by either A or B.

b)

Let's denote event A as A fixing the computer and event B as B fixing the computer.

P(A) = 0.30 (probability A can fix the computer)

P(B|A') = 0.40 (probability B can fix the computer given that A cannot)

To find P(B|A), the probability that B fixes the computer given that it was fixed, use Bayes' theorem:

P(B|A) = (P(A|B) * P(B)) / P(A)

Since the computer is fixed, P(A) + P(A') = 1, so P(A) = 1 - P(A') = 1 - 0.30 = 0.70

P(B|A) = (P(A|B) * P(B)) / P(A)

P(B|A) = (1 * 0.40) / 0.70

P(B|A) = 0.40 / 0.70

P(B|A) ≈ 0.5714

Hence, if the computer is fixed, there is a 57.14% probability that it was fixed by B.

Answer:

There are four main types of transformations: translation, rotation, reflection and dilation.Translation moves the object without rotating it or changing its size. Reflection flips the object about a line of reflection. Rotation rotates a figure about a fixed point. Dilation changes the size of a figure without changing its essential shape.When you reflect a point across the x-axis, the x-coordinate remains the same,but the y-coordinate is transformed into its opposite. a negative angle of rotation turns the figure in a clockwise direction.Transformation can be done in a number of ways, including reflection, rotation, and translation. ~When you reflect a point across the x-axis, the x-coordinate remains the same,but the y-coordinate is transformed into its opposite. a negative angle of rotation turns the figure in a clockwise direction.

Step-by-step explanation:

Transformation simply means changing the size and location of shapes, lines and points in the coordinate geometry

The similarities

Translations, reflections, and rotations are all rigid transformations

This means that, they do not change the side lengths and angle measure of the shape they transform.

The differences

Translation: can only change the position of shapes without rotating or flipping the shape.

Rotation: This means that a shape is to be turned around a center at a particular degree

Reflection: This simply means that, a shape is mirrored over a line

Real-world transformation

A scenario is when the blades of a fan rotates when the fan is powered on

Answer:

$ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample

Step-by-step explanation:

Here

Z∝ =1.64

Standard Deviation=S= 0.21

Sampling Error= SE= 0.05

As Sampling Error is found by

SE= z * s/√n

√n= z*s/ SE

n= (z* s/ SE)²

We use the above formula  to calculate N

N= ( Z * S/SE)²

N= (1.64 * 0.21/0.05)²

N= 28.9296= 28.93

Cost of N number of burgers

= Cost *N

= $1.29 * 28.93= $ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample

Answer:

The probability is    [tex]P(C | I) =  0.025[/tex]    

Step-by-step explanation:

From the question we are told that

      The  proportion analyzed by  Amir is  P(A) =  0.55

      The proportion analyzed by  Betty is  P(B)  =  0.30

     The  proportion analyzed by  Carlos is  P(C) =  0.15

     The inaccuracy by  Amir  is   p = 0.6% =  0.006

     The inaccuracy by  Betty  is  b = 0.4% = 0.004

    The inaccuracy by  Carlos  is c = 0.1% =  0.001

Generally the probability of inaccurate analysis is mathematically represented as

     [tex]P(I) =  P(A) *  p  +  P(B) *  b  +  P(C) *  c[/tex]

=>  [tex]P(I) =  0.55 * 0.006  +  0.30  *  0.004  +  0.15  *  0.001 [/tex]

=>  [tex]P(I) =  0.006 [/tex]

Generally the probability that an inaccurate analysis, detected at final verification, was conducted by Carlos is mathematically represented as

       [tex]P(C | I ) =  \frac{P(C) *  c}{P(I)}[/tex]

=>     [tex]P(C | I) =  \frac{   0.15  *  0.001}{ 0.006}[/tex]

Answer:

the fraction and its decimal equivalent for the mark on the ruler

= 59/64 = 0.921875

Step-by-step explanation:

Given that;

A CARPENTER 's ruler is marked in thirty  seconds

mark on the ruler between 29/32 and 30/32​ is the average of the values

we know that average is the summation of all terms divided by the number of appearance of terms

so

= (29/32 + 30/32​) / 2

= ((29 + 30) / 32) / 2

= (59 / 32) / 2

= 59 / 64

= 0.921875

therefore the fraction and its decimal equivalent for the mark on the ruler = 59/64 = 0.921875

Answer:

The probability that the town has 30 or fewer residents with the illness = 0.00052.

Step-by-step explanation:

So, we have the following set of data or information or parameters given from the question above and they are; the number of people living in that particular society/community/town = 74,000 residents and the proportion of people that the diseases affected = .000215.

The first step to do is to determine the expected number of people with disease. Thus, the expected number of people with disease = 74,000 × .000215 = 15.91.

Hence, the probability that the town has 30 or fewer residents with the illness = 1.23 × 10^-7 × 15.91^30/ 2.65253 × 10^-32 = 0.00052.

Note the formula used in the calculating the probability that the town has 30 or fewer residents with the illness =  e^-λ × λ^x/ x!

Answer:

5/6

Step-by-step explanation:

First, you need to make sure they have a common denominator, or else addition is not possible.

Luckily, in this case, 6 and 3 are divisible.

You would multiply 2 by 2/3 to get the common denominator of 6

The new expression would be:

4/6 + 1/6

Now, you just need to add the numerators

4 + 1 = 5

The correct answer would be 5/6.
