0.003 is  the expected value and the standard deviation of the distribution.

What does a probability simple definition entail?

A probability is a number that expresses the possibility or likelihood that a specific event will take place.

                          Both proportions between 0 and 1 and percentages between 0% and 100% can be used to describe probabilities.

Let X shows the random variable corresponding to binomial distribution in the question.

 (a)

      Expected value of the binomial distribution is

       μ = E(X) = ηp =  20 . 040  = 8

and

   σ = √np( 1 - p )  = √20 .04.( 1 - 0.40 )  = √4.8  = 2.19

(b)

For a binomial distribution it is unusal to obtain the sucesses the less than μ - 2.5σ  and greater than μ + 2.5σ

here r = μ - 2.5σ  = 8 - 2.5 . 219 = 2.525

That is for the given binomial distribution it is unusal to obtain the number of successes less than 2.5 or approximately less than 3.

Probability of less than 3 sucesses is

  P( X < 3 ) = P( X≤ 2 ) = P(X=0) + P( X = 1 ) + P( X = 2 )

                  = 2∑k=0 (k²⁰) [tex]( 20 )^{k} ( 1 - 0.4)^{20 - k}[/tex]

The slope-intercept equation of the line is y= 9x + 3

The line with m as the slope, m and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.

The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, ab, denotes the y-coordinate of the location where the line's graph crosses the y-axis.

Slope-intercept form of an equation: y=mx+b, where m is the slope (in this case, 9) and b is the y-intercept (in this case, the 3 from the point 0, 3)

y= 9x + 3 ( Plug in 9 for the m (slope) and 3 for the b (y-intercept))

Thus, the slope-intercept equation of the line is y= 9x + 3

The mean of the total sum of the balls remaining is (n-k)(n+1)/2 and the variance of the total sum of the balls remaining is  k(n-k)(n+1)/6

The mean of the total sum of the balls remaining in the urn is calculated by finding the average of each number of the remaining balls and summing them up. To find the variance, we use the formula for the variance of a discrete uniform distribution, which states that the variance is equal to the range of the distribution squared divided by 12. In this case, the range is n-k, since we have removed k balls, and the number of remaining balls will range from 1 to n-k.

When there is only one compounding every time period, simple interest is applied.

Following t years, the amount of money is predicted by:

A(t) = A(0) (1 + rt)

That where:

The initial amount is A(0).

The interest rate in decimal form is r.

In this issue:

The starting sum is A(0) = 100000.

R = 0.105 is the interest rate.

The maturity value is 104375 for A(t).

Therefore, we must find t; as a result,

A(t) = A(0)(1 + rt)

104375 = 100000(1 + 0.105t)

1 + 0.105t = 104375 / 100000

1 + 0.105t = 1.04375

The theoretical probability of the spinner not landing on blue is 0.625.

Probability is a way to gauge how likely something is to happen. According to the probability formula, the likelihood that an event will occur is equal to the proportion of positive outcomes to all outcomes. The probability that an event will occur P(E) is equal to the ratio of favorable outcomes to total outcomes.

Given A spinner with repeated colors numbered from 1 to 8 is shown,

total outcome = 8

a favorable outcome for blue = 3

a favorable outcome for red = 1

a favorable outcome for purple = 2

a favorable outcome for yellow =  2

probability =  favorable outcome/total outcome

P(blue) = 3/8

P(blue) = 0.375

P(not blue) = 1 - P(blue)

P(not blue) = 1 - 0.375

The expression for the electric field strength at 1/2 R is E = 8 * π * k * q * r^2 / (1/2R)^2, and the expression for the electric field strength at 2R is E = 2 * π * k * q * r^2 / (2R)^2.

What is the spherical shell?

In geometry, a spherical shell is a generalization of an annulus to three dimensions. It is the region of a ball between two concentric spheres of differing radii.

(A) Electric field strength at 1/2R:

The electric field strength at a point P due to a charge q located at point O is given by:

E = k * q / r^2

where k is the Coulomb constant, q is the charge at point O, and r is the distance between points P and O.

For a spherical shell of radius R carrying charge 2q spread uniformly over its surface, the electric field at any point inside the shell is zero, since the charges on the shell produce equal and opposite electric field vectors that cancel each other out.

Therefore, the electric field strength at 1/2R is zero.

(B) Electric field strength at 2R:

At a distance of 2R from the center of the spherical shell, the electric field due to the entire shell can be calculated as if all the charge were concentrated at the center of the shell.

The electric field strength at a point P due to a point charge q located at the center of the spherical shell is given by:

E = k * q / r^2

where k is the Coulomb constant, q is the total charge on the shell (2q), and r is the distance between points P and the center of the shell (2R).

So, the electric field strength at 2R is:

E = k * (2q) / (2R)^2 = k * q / R^2

Hence, the expression for the electric field strength at 1/2 R is E = 8 * π * k * q * r^2 / (1/2R)^2, and the expression for the electric field strength at 2R is E = 2 * π * k * q * r^2 / (2R)^2.

The total  fencing they required = 38x + 10.

The family needs yards of  fencing of the home = 160 yards

The family needs yards of fencing of the pool = 40 yards

Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.

Perimeter = Sum of length of the all the sides

Perimeter of a rectangle = 2(length + width)

Perimeter of a square = 4(side length).

Given that,

A rectangle labeled home has its right side labeled (2 + 5 x) yards

And bottom side labeled (3 + 10 x) yards

Perimeter for the rectangular fencing of the home = 2(3 + 10x + 2 + 5x) = 2(15x + 5) = 30x + 10

Perimeter for the square fencing of the pool = 4(2x) = 8x

The total amount of fencing they need = 30x + 10 + 8x = 38x + 10.

If x = 5, then:

Perimeter for the rectangular fencing of the home = 30x + 10 = 30(5) + 10 = 160 yards

The Domain for the function g(x) = (x² - 3x - 18)/(x² − 4) is , all Real vales except x = 2 and x = -2 .

The Domain of a function is the set of all possible input values (values of x) for which the function is defined and produces a valid output (value of y).

For the function g(x) = (x² - 3x - 18)/(x² − 4), the only restriction on the domain is the denominator (x² − 4) cannot be equal to 0. This is because division by zero is undefined.

So, the domain of the function g(x) is all real numbers except x = ±2, because if we substitute x = 2 or -2 , the denominator becomes 0 and hence undefined .

0.25x + 0.10(x + 7) = 27.30

0.25x + 0.10x + 0.7 = 27.30

0.35x = 27.30 - 0.7

Answer:

Step-by-step explanation:

This is an arithmetic sequence with a common difference of -12. To find the recursive formula, let's start by finding a general formula for the nth term.

Let a be the first term (3 in this case) and d be the common difference (-12 in this case). The nth term of the sequence can be found using the formula:

an = a + (n-1)d

Using this formula, the first four terms of the sequence are:

a1 = a + (1-1)d = 3 + (1-1)(-12) = 3

a2 = a + (2-1)d = 3 + (2-1)(-12) = 3 - 12 = -9

a3 = a + (3-1)d = 3 + (3-1)(-12) = 3 - 24 = -21

a4 = a + (4-1)d = 3 + (4-1)(-12) = 3 - 36 = -33

So, the sequence is: 3, -9, -21, -33, ...

We can now use this information to write the recursive formula for the sequence:

an = a(n-1) + d

So, for the sequence 3, -9, -21, -33, ... the recursive formula is:

an = an-1 + (-12)

This formula tells us how to find the nth term of the sequence given the (n-1)th term. The sequence starts with the first term a1 = 3 and the common difference is d = -12. By repeatedly applying the formula, we can find the values for the subsequent terms in the sequence.
