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:

x = 11

Step-by-step explanation:

It is given that,

Points H, G and F are collinear. Point G is between H and G.

It means,

HG = GH + HG

We have, HG = x, GH = 1, HG = 10

Putting all the values, we get:

x = 1 +10

x = 11

It is very clear that the value of x is 11.

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

Solution:

Order of operations:

1- Parentheses

2- Exponent

3- Multiply

4- Divide

5- Subtract

By using these operations we can find out the solution of 4’s to create problems that will equal to     1 – 12.

1 = 44 / 44   or (4+4) / (4+4)

2= 4/4 + 4/4

3 = (4+4+4) /4

4 = 4 x (4 – 4) +4

5 = (4 x 4 + 4)/ 4

6 = 4 x .4 + 4.4

7 = 44 / 4 – 4

8 = 4 + 4.4 - .4

9 = 4/4 +4 +4

10 = 44 / 4.4

11= 4 / .4 + 4/4

12 = (44 + 4) / 4

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]

Answer:

a. Amount of time spent shopping for clothing in the past week = CONTINUOUS NUMERICAL

b. Preferred brand of shoes = CATEGORICAL

c. Number of deliveries received at the household per week = DISCRETE NUMERICAL

d. Most likely time period during which shopping for clothing takes place (weekday, weeknight, or weekend) = CATEGORICAL

Step-by-step explanation:

Determine whether variable is Categorical or Numerical (Discrete or continuous) :

Categorical variables are used in grouping data values into a defined set of classes or distinct groups. Numerical variables are those usually represented with numbers and this posses numerical meaning. Numerical variables can either be discrete when the values in the dataset are finite or continuous, when values aren't finite and usually uncountable.

a. Amount of time spent shopping for clothing in the past week = CONTINUOUS NUMERICAL

b. Preferred brand of shoes = CATEGORICAL

c. Number of deliveries received at the household per week = DISCRETE NUMERICAL

d. Most likely time period during which shopping for clothing takes place (weekday, weeknight, or weekend) = CATEGORICAL

Categorical Variables : b) Preferred shoe brand; & d) Likely period of shopping

Numerical Continuous Variable : a) Amount of shopping time ; & Numerical Discrete Variable : c) Number of deliveries

Numerical Variables, as the name denotes - can be expressed in numbers. Like : Number of variable x.

Categorical Variables, as the name denotes - cant be expressed n numbers but rather in categories. Like : A person being man, woman or other gender.

A] Amount of time spent shopping for clothing in the past week : Numerical & Continuous, can be in decimal values like 2.8 , 4.5 hours etc

B] Preferred brand of shoes : Categorical Variable, will be amongst the brand names like Pima, Nuke etc

C] Number of deliveries received at the household per week : Numerical & Discrete , can be only in non decimal whole values - like 4 , 5 , 10 etc

D] Most likely time period during which shopping for clothing takes place : Categorical Variable, will be amongst the mentioned period of weeks or days - like weekday, weeknight, or weekend

Step-by-step explanation:

I think is 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

Examples

Reflection

Rotation

Answer:

The amount of income tax in dollars and cents is $4,695.75

Step-by-step explanation:

To find the amount of income tax that should be paid, we simply use the percentage said to be for the income tax

Mathematically;

income tax = 9% of 52,175

= 9/100 * 52175

= $4695.75

The income tax to be paid on the income is $52,175

Answer:4695.75

Step-by-step explanation:

Well if u made 52175 a whole then put 9 as a percentage you would cross multiply 52175 with 9 then divided with the whole percentage (100)

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.
