The probability exactly three successes in six trials is 31.30%

A binomial distribution can be defined as the probability of a success or failure outcome in an experiment or survey that is repeated multiple times.

The probability distribution of a binomial distribution is given by :

P(x = k) = n! /k!(n - k)! P^x(1 - P)^(n - k)

In our case :

n = 6

P = 50/100 = 0.5

Now we want the probability that:

x = 3

This is because the question states that we want the probability that the number of successes are exactly 3.

We do the substitution in the probability distribution function as follows :

P(x = 3) = 6!/3!(6 - 3)! × 0.5³ × (1 - 0.5)³

= 0.3125

= 31.25%

= 31.30%

Hence, the probability of exactly three successes in six trials of a binomial experiment in which the probability of success is 50 is 31.30%

Step-by-step explanation:

The linear equation in the form p(n) = mn + b that gives the price p they can charge for n shirt is p(n) = - 1 / 250n + 34.

Linear equation can be represented in slope intercept form as follows:

y = mx + b

where

Therefore, the clothing business finds there is a linear relationship between the number of shirts, n,  it can sell and the price, p , it can charge per shirt.  1,000 shirts can be sold at a price of $30 , while 3,000 shirts can be sold at a price of $22 .

Therefore,

using  (1000, 30) and (3000, 22) let's find the slope.

m = 22 - 30 / 3000 - 1000

m = - 8 / 2000

m = - 1 / 250

Hence, let's find the y-intercept using (1000, 30)

p(n) = mn + b

where

Therefore,

30 = - 1 / 250 (1000) + b

30 = - 4 + b

b = 30 + 4

b = 34

Hence, the linear equation is p(n) = - 1 / 250n + 34

Answer:

7 and 1/24

Step-by-step explanation:

4 7/8 + 2 1/6

First when adding fractions, we want to have a common denominator. To do that, we must multiply the fractions until we get a desired denominator. We can find LCM.

The LCM of 6 and 8 is 24, so we must multiply accordingly.

We can put this into improper fraction form:

39/8 + 13/6

Then multiply accordingly. Multiply by 3 on both sides for the first fraction, and multiply by 4 on both sides for the second to get a denominator of 24.

117/24 + 52/24

Now, we can add the fractions.

The volume of a cone increase more when you double the height of the original or when you double its radius. This is true.

A cone is a shape formed by connecting a common point, known as the apex or vertex, to all the points of a circular base with a set of line segments. The height of the cone is the distance from the vertex to the base.

A cone always contains a right angle. To solve for the volume of a cone, we need to get the radius of the cone and its height. radius is the line from the center of the circle of the cone going to the edge of the circle. height is the measurement of the cone from its pointy tip going downward.

The volume of a cone is 1/3πr²h, so if you double the radius the volume would quadruple. So, when the height is doubled, the volume is also doubled.

The option that doesn't describe slope is A. A line joining points.

Slope is determined by dividing the vertical change by the horizontal change between two distinct points on a line.

It is defined as the difference in y coordinate divided by the difference in x coordinate between two distinct points on the line.

A line's slope is a number that describes both its direction and its steepness. Slope is a measure of change or a constant rate of change between two points.

As a result, from the options given, slope is not a line segment connecting two points, but rather the change in a line segment between two points.

It should be noted that the correct option is A.

First: 0 x 0 = 0 (so you put):

6370                                                                                                                              x   30

      0

(everything else times 0 just equals 0 so you'd get this):

6370                                                                                                                              x   30

    0

Next: 3 x 7 = 21 (so you put):

0000

 1 10

(add the number you carried to 9: giving you 11 so you also have to carry a 1 again)

(the first number: 0 of 110 goes under the third 0 of 0000)

(the spacing is just to make sure that the placement is correct: the first 1: of 110 goes under the first 0 of 0000)

Next: 3 x 6 = 18 (so you put):

1 2

6370                                                                                                                              x   30

  0000

191 10

(you add the 1 that you carried to 18 to give you 19)

(again: I only moved the zeros over so that the placement is correct)

Next: Now you add(this is why the placement of the numbers is important):

1 2

6370                                                                                                                              x   30

     0000

+ 191 10

  191,100

(you will put imaginary zeros over 19 because you know that there is already nothing there. You will also add an imaginary zero under the last zero that is hanging there because you know there is nothing there either.)

The function is given in the question as

m(x) = xcos(-x)

Taylor (Maclaurin) series of xcos(x) up to n=5

A Maclaurin series is given by  f(x),

[tex]f\left(x\right)=f\left(a\right)+\frac{f^'\left(a\right)}{1!}\left(x-a\right)+\frac{f^{''}\left(a\right)}{2!}\left(x-a\right)^2+\frac{f^{'''}\left(a\right)}{3!}\left(x-a\right)^3+\ldots[/tex]

[tex]f\left(x\right)=f\left(0\right)+\frac{f^'\left(0\right)}{1!}\left(x\right)+\frac{f^{''}\left(0\right)}{2!}\left(x\right)^2+\frac{f^{'''}\left(0\right)}{3!}\left(x\right)^3+\ldots[/tex]

We need to do to get the desired polynomial is to calculate the derivatives, evaluate them at the given point, and plug the results into the given formula.

f⁽⁰⁾(x) = f(x) = xcos(x)

Evaluate the function at the point: f(0)=0

1st derivative: f(1)(x)=(f(0)(x))′=(xcos(x))′=−xsin(x)+cos(x)

1st derivative at the given point: (f(0))′=1

2nd derivative: f(2)(x)=(f(1)(x))′=(−xsin(x)+cos(x))′=−xcos(x)−2sin(x)

Evaluate the 2nd derivative at the given point: (f(0))′′=0

3rd derivative: f(3)(x)=(f(2)(x))′=(−xcos(x)−2sin(x))′=xsin(x)−3cos(x)

Evaluate the 3rd derivative at the given point: (f(0))′′′=−3

Now, use the calculated values to get a polynomial:

[tex]m(x)=0+\frac{1}{1!}x+\frac{0}{2!}x^2+\frac{-3}{3!}x^3+.....[/tex]

[tex]m(x)=x-\frac{1}{2}x^3+\frac{1}{24}x^5-\frac{1}{720}x^7+\frac{1}{40320}x^9+\ldots \:[/tex]

Thus, the Maclaurin series of xcos(-x) up to n = 3 is

[tex]m(x)= xcos(-x)= x-\frac{1}{2}x^3+\frac{1}{24}x^5-\frac{1}{720}x^7+\frac{1}{40320}x^9+\ldots \:[/tex]

The transformation of System A into System B is:

Equation [A2]+ Equation [A 1] → Equation [B 1]"

The correct answer choice is option D

To transform System A into System B as 1 × Equation [A2] + Equation [A1]→ Equation [B1] and 1 × Equation [A2] → Equation [B2].

System A:

-3x + 4y = -23 [A1]

7x - 2y = -5 [A2]

Multiply equation [A2] by 2

14x - 4y = -10

Add the equation to equation [A1]

14x - 4y = -10

-3x + 4y = -23 [A1]

11x = -33 [B1]

Multiply equation [A2] by 1

7x - 2y = -5 ....[B2]

So therefore, it can be deduced from the step by step explanation above that System A is ultimately transformed into System B as 1 × Equation [A2] + Equation [A1]→ Equation [B1] and 1 × Equation [A2] → Equation [B2].
