for each positive integer n, what is the largest value of p such that zero is the most likely number of successes in n independent trials with success probability p?

Answers

Answer 1

The largest value of success probability p with zero as most likely number of success with n independent trials is equal to 1 / ( n + 1 ).

Probability of success is equal to p

Probability of failure is equal to ( 1 - p)

Number of trials is positive integer n

Condition for 'n' independent trials :

Zero is most likely number of success

⇒ P(0) ≥ P(1)

⇒ ⁿC₀ p⁰ ( 1 - p )ⁿ⁻⁰  ≥ ⁿC₁ p¹ ( 1 - p )ⁿ⁻¹

⇒ ( 1 - p )ⁿ ≥ np ( 1 - p )ⁿ⁻¹

⇒( 1 - p ) ≥ np

⇒ np + p ≤ 1

⇒ p ≤  1 / ( n + 1 )

Largest value of p is equal to 1 / ( n + 1 ).

Therefore, the largest value of success probability p with n independent trials is equal to 1 / ( n + 1 ).

what is coefficient ?

In maths, a coefficient is a cubic, a sequence, or the exponential coefficient of a descriptive word in an expression. Any phrase is acceptable, though digits are frequently used. If the equations are variables, and so the word "parameter" also could refer to the variables themselves. A coefficients is the product of either a number and then a variable. Some occurrences of correlations are: The coefficient as in sentence . The variable is multiplied by it amount when word g has a coefficient of 1. example Since "z" is a factor and the term's interpretation is 6z, the multiplier is 6. The square root of x has a score of one.

given

((8k +  (k2)) -  6) -  ((7 - 10k) -  2k2)

The first term is 3k2 and it has a 3 coefficient.

The coefficient of the middle word, +18k, is 18.

"The constant," the final term, is -13.

Step 1: Add the constant 3 • -13 to the coefficient of the first term to get -39.

Projab is the projection of vector a onto vector b. It is a vector that is perpendicular to b and has the same magnitude as a, and it is the vector that is closest to a in the direction of b.

In R2, the geometric interpretation is that projab is the vector that is obtained by dropping a perpendicular line from the tip of a onto the line containing b.

In R3, the geometric interpretation is that projab is the vector that is obtained by dropping a perpendicular line from the tip of a onto the plane containing b.

The value of t is 8 and the value of r is 8√2. The solution has been obtained by using trigonometry.

What is trigonometry?

The study of triangle sides, angles, and relationships is the focus of the mathematical field of trigonometry.

We are given a right angled triangle with an angle 45° and the perpendicular measuring 8.

Using trigonometry,

We know that tan theta = opposite side/ adjacent side

So,

⇒tan 45° = 8/t

⇒1 = 8/t (tan 45° = 1)

t = 8

Similarly,

We know that cos theta = adjacent side/hypotenuse

So,

⇒cos 45° = 8/r

⇒1/√2 = 8/r (cos 45° = 1/√2)

r = 8√2

Hence, the value of t is 8 and the value of r is 8√2.

How to interpret the Electric Force on an object?

The amount of charge on an object due to the effect of the force that is exerted on it can be calculated by using the formula :

F = E × q

Where;

F is the electric force.

E is the energy.

q is the charge.

The electric force between charged particles at rest is known as electrostatic force.

The magnitude of the electric force between point charges is directly proportional to the multiplication of the charges and inversely proportional to the distance between them.

Therefore, we conclude that increasing the amount of charge on an object would increase the electric force because the amount of charge has a direct relationship with the force.

I have a mixture of 135 M&Ms. They come in the colors, red, blue, yellow and brown. There are five more blue M&Ms than red ones. The number of yellow M&Ms is nine less than the number of red ones. The number of brown M&Ms is thirteen more than half the number of red ones. Find the number of red, blue, yellow and brown M&Ms.

Answers

Answer:

Let x be the number of red M&Ms.


Then the number of blue M&Ms is x + 5, the number of yellow M&Ms is x - 9, and the number of brown M&Ms is (1/2)x + 13.


The total number of M&Ms is 135, so we can write an equation:


x + (x + 5) + (x - 9) + (1/2)x + 13 = 135


Simplifying this equation, we get:


3.5x + 9 = 135


Subtracting 9 from both sides, we get:


3.5x = 126


Dividing both sides by 3.5, we get:

x = 36


So there are 36 red M&Ms, 41 blue M&Ms (36 + 5), 27 yellow M&Ms (36 - 9), and 31 brown M&Ms (1/2 * 36 + 13).

Answer:

Step-by-step explanation:

r: the number of red M&Ms

b: the number of blue M&Ms

y: the number of yellow M&Ms

br: the number of brown M&Ms

We can translate the given information into equations:

r + b + y + br = 135 (the total number of M&Ms is 135)

b = r + 5 (there are five more blue M&Ms than red ones)

y = r - 9 (there are nine less yellow M&Ms than red ones)

br = 13 + (1/2)r (there are thirteen more brown M&Ms than half the number of red ones)

We can use equations 2, 3, and 4 to substitute for b, y, and br in equation 1:

r + (r + 5) + (r - 9) + (13 + (1/2)r) = 135

Simplifying this equation, we get:

3.5r + 9 = 135

Subtracting 9 from both sides, we get:

3.5r = 126

Dividing both sides by 3.5, we get:

r = 36

Now that we know the value of r, we can use equations 2, 3, and 4 to find the values of b, y, and br:

b = r + 5 = 36 + 5 = 41

y = r - 9 = 36 - 9 = 27

br = 13 + (1/2)r = 13 + (1/2)(36) = 31

Therefore, the number of red, blue, yellow, and brown M&Ms in the mixture are 36, 41, 27, and 31, respectively.

How to find sum of interior and exterior angles of a polygon?

Polygon A

A polygon with 9 sides is called a nonagon. The sum of interior angles of a Nonagon is 1260°. This can be calculated using the formula (n -2) * 180, where n is the number of sides.

Thus, the sum of the interior angles of polygon A is 1260°.

The sum of the exterior angles of a polygon is 360°.Thus, the sum of angles of the exterior angles of a polygon A is 360°.

Polygon B

Polygon B has 7 sides i.e. n = 7

sum of angles of the interior angles of polygon B = (7-4) * 180 = 900°

Thus, y = 900- 135 - 140 - 150 - 120 - 135 - 120 = 100°

Two lamp posts are of equal height. A boy standing mid-way between then observes the elevation of the top of either post to be 30∘. After walking 15 m towards one of them, he observes the elevation of it stop to be 45∘. Find the heights of the posts and the distance between them.​(Ans:20.49m,70.98m)

Answers

Answer:

The height of the lamp posts is 20.49 m and the distance between them is 70.98 m.

Step-by-step explanation:

Draw a diagram using the given information (see attachment).

The lamp post is at point C (the top of the lamp post is at point D).The height of the lamp post is labelled "h".The boy is at point A.After walking 15 m towards one of the lamp posts, the boy is at point B.The distance between both lamp posts is 2x.

[tex]\boxed{\begin{minipage}{7 cm}\underline{Tan trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\end{minipage}}[/tex]

Use the tan trigonometric ratio to create two equations for h.

Triangle ACD:

[tex]\implies \tan 30^{\circ}=\dfrac{h}{x}[/tex]

[tex]\implies h=x\tan 30^{\circ}[/tex]

[tex]\implies h=\dfrac{\sqrt{3}}{3}x[/tex]

Triangle BCD:

[tex]\implies \tan 45^{\circ}=\dfrac{h}{x-15}[/tex]

[tex]\implies h=(x-15)\tan 45^{\circ}[/tex]

[tex]\implies h=(x-15)\cdot 1[/tex]

[tex]\implies h=x-15[/tex]

Substitute the second equation into the first equation and solve for x:

[tex]\implies x-15=\dfrac{\sqrt{3}}{3}x[/tex]

[tex]\implies x-\dfrac{\sqrt{3}}{3}x=15[/tex]

[tex]\implies \dfrac{3-\sqrt{3}}{3}x=15[/tex]

[tex]\implies (3-\sqrt{3})x=45[/tex]

[tex]\implies x=\dfrac{45}{3-\sqrt{3}}[/tex]

[tex]\implies x=35.4903810...[/tex]

To find h, substitute the found value of x into the second equation and solve for h:

[tex]\implies h=x-15[/tex]

[tex]\implies h=35.4903810...-15[/tex]

[tex]\implies h=20.4903810...[/tex]

[tex]\implies h=20.49\; \sf m\;\;(2\;d.p.)[/tex]

As the distance between the two lamp posts is 2x:

[tex]\implies 2x=2 \cdot 35.4903810...[/tex]

[tex]\implies 2x=70.9807621...[/tex]

[tex]\implies 2x=70.98\; \sf m\;\;(2\;d.p.)[/tex]

Therefore:

The height of the lamp posts is 20.49 m.The distance between them is 70.98 m.

b. Rate of change for linear function B:
Question Blank 2 of 3
type your answer...

Answers

Answer:

Step-by-step explanation:

The rate of change is just the slope of the equation and/or graph.

for the linear function A, y = 2/3x + 5, the slope (therefore rate of change) is 2/3. For B (I can't make it out that clear), 3/2. That gives the answer for C: 3/2 is greater than 2/3.
