What is a binomial distribution?

The binomial distribution with parameters n and p in probability theory and statistics is the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-no question and each with its own Boolean-valued outcome: success or failure.

Let X be the random variable.

The number of trials n = 15, P=0.15

X ~ Bin(n, p)

Part A:

      [tex]P(X=x)= {n \choose x} (p)^{x} (1-p)^{n-x}[/tex]

      [tex]P(X=x)= {15 \choose x} (0.15)^{x} (0.85)^{15-x}[/tex], x=0, 1, 2, 3,..., 15.

Part B:

    [tex]P(X=1)= {15 \choose 1} (0.15)^{1} (0.85)^{15-1}\\\\P(X=1)= {(15)} (0.15) (0.85)^{14}\\\\P(X=1)=0.2312[/tex]

Part C:

     [tex]P(X=2)= {15 \choose 2} (0.15)^{2} (0.85)^{15-2}\\\\P(X=2)= {(105)} (0.15)^2 (0.85)^{13}\\\\P(X=2)=0.2856[/tex]

Part D:

 [tex]P(X\geq 2)= 1-P(X < 2)\\\\P(X\geq 2)=1-P(X=0)-P(X=1)\\\\P(X\geq 2)=1-0.0873-0.3212\\\\P(X\geq2)=0.6814[/tex]

Part E:

  The probability of none of the children getting the disease will be

             [tex]P(X=0)= {15 \choose 0} (0.15)^{0} (0.85)^{15-0}\\\\P(X=0)= {(1)} (1) (0.85)^{15}\\\\P(X=1)=0.8734[/tex]

Hence,

Part A: [tex]P(X=x)= {15 \choose x} (0.15)^{x} (0.85)^{15-x}[/tex], x= 0, 1, 2, 3, ..., 15.

Part B: P(X = 1) = 0.2312

Part C: P(X = 2) = 0.2656

Part D: P(X ≥ 2) = 0.6814

The probability that the drawn marble is green is 5/9.

What do you mean by an intersection in probability?

P(A∩B) denotes the probability of A and B occurring together, also known as the likelihood of A intersecting with B, or the likelihood of two occurrences occurring concurrently, or the probability of two events occurring simultaneously.

We define the intersection of two events as the set of all results that occur for any two events A and B. In other words, if both A and B happen, the intersection will happen. A and B are crossed when A∩B is used as a symbol.

Solution Explained:

Total number of white marbles = 6

Total number of black marbles = 2

Total number of green marbles = 10

Marbles in total = 6 + 2 + 10 = 18

A marble is drawn on random

Therefore, the probability of the marble being green P(G) = 10/18 = 5/9

It is given to us that -

Amount of time a person experiences cold virus symptoms are normally distributed with

a mean of 7.5 days

and, a standard deviation of 1.5 days

We have to find out the proportion of cold sufferers that experience symptoms for more than 8 days.

Now, from the given information, we have

Mean = μ = 7.5

Standard deviation = σ = 1.5

and, X = 8

Now, the proportion of cold sufferers that experience symptoms for more than 8 days can be represented as -

P(X > 8)

Answer:

  x +2y = -2

Step-by-step explanation:

You want the line perpendicular to 2x-y = 5 that passes through (6, -4).

The slopes of perpendicular lines are opposite reciprocals. This means the equation of the perpendicular line can be formed by swapping the coefficients of x and y, and negating one of them. We want the leading coefficient to be positive, so we choose our line's equation to be ...

  2x -y = constant . . . . . . . . . . original line

  x +2y = <some constant>

The constant must be chosen so the equation is true at the given point:

  x + 2y = (6) +2(-4) = -2

An equation for the perpendicular line is ...

  x +2y = -2

What is rectangular prisms?

A three-dimensional solid form with six faces, including rectangular bases, is called a rectangular prism. A rectangular prism also refers to a cuboid. A cuboid and a rectangular prism have the same cross-section.

Length, width, and height formula for a rectangular prism that represents its volume: The lengths of a rectangular prism's three distinct dimensions (length, width, and height) are multiplied together to determine the volume of the object. A volume formula for rectangular prisms is as follows:

                                         V = lwh

The prism's base is a rectangle with the dimensions (l, w) and (h), and the height (h) is the separation between the two bases at a perpendicular angle.

Rectangular prism volume formula based on base area and height: The area of a rectangular prism's one side can be used to determine the prism's base, or area B.

Probability is number of weeks/ 100 weeks

x=0, number of weeks is 3

P=3/100=0.03

x=1, number of weeks is 20

P=20/100=0.2

x=2, number of weeks is 50

The symbol a < b indicates that an is less than b.

The symbol a > b indicates that an is greater than b.

These are known as strict inequalities, because an is strictly less than or strictly bigger than b. Equivalence is not allowed.

Each side of square loop wire , L = 2.00 cm

Square loop carring current , I₂ = 0.230 A

Solenoid , has n= 30 turns/cm

Current Carrying in solenoid, I₁ = 15.0 A

Magnetic field inside solenoid , B = μ₀ n I₁

where, μ₀---> susceptibility of free space

μ₀ = 4π×10⁻⁷A/m

pulgging all known values in above formula,

B = (4π×10⁻⁷ A/m) 30 turn/cm × 100cm /1m (15.0 A)

What is the age problem?

Age problems are algebra word problems that deal with the ages of people currently, in the past, or in the future.

Let the present age of the son be 'x'

Then, the present age of the father will be '3x'

According to the question,

The age of the son after 12 years = (x+12) years

And the age of the father after 12 years = 2(x+12) years

Therefore,

or, 3x+12=2(x+12)

or, 3x+12=2x+24

or, x=12

A percentage is a figure or ratio stated as a fraction of 100 in mathematics.

We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.

We place the percent symbol (%) next to the number to indicate that the number is a percentage.

For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

To get what percentage one number is of another:

We divide the number by another number, use that other number as the base, and multiply the result by 100 to determine the percentage.

Let's use an example to further understand this:

The equation represents the line that passes through (- 6, 7) and (- 3, 6) is  y = -1/3x +5

The slope-intercept form is just a means of formulating a line's equation so that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are clearly visible. This form is frequently referred to as the y = mx + b form. This line form is one of the most prevalent in algebra classes.

A line's slope-intercept form is y = mx + b, where m is its slope and b is its y-intercept.

The equation of the line which is passing through two points is:

y₂-y₁ / x₂-x₁

(6-7)/(-3+6)=-1/3

A line's slope-intercept form is y =mx +b, where m is the slope and b is the y intercept.

y = -1/3 x +b. We must now calculate b, the y intercept. To find b, plug one of the given points into the previous equation and solve for b.

6 = -1/3(-3) + b
