two gamblers are playing a coin toss game. gambler a has (n 1) fair coins; b has n fair coins. what is the probability that a will have more heads than b if both flip all their coins
The more coins that are tossed for both gamblers, the less advantageous Gambler A is. But when a few coins are tossed, Gambler A will continue to hold a significant edge.
The binomial distribution;
In probability theory and statistics, the binomial distribution with parameters n and p is used to describe the discrete probability distribution of the number of successes in a set of n independent experiments.
Let X be the number of wins in the first n flips by A, Y be the signal that the last flip by A also wins, and Z be the number of wins in the n flips by B.
As Y is unrelated to X and Z, the following follows:
P(X + Y > Z) = P(Y = 1) P(X ≥ Z) + P(Y = 0) P(X > Z)
= 1/2(P(X = Z) + 2P(X > Z))
P(X > Z) = P(Z > X)
Here,
The less favorable Gambler A is, the more coins are tossed for both players. However, Gambler A will continue to have a sizable advantage even after a few coins are tossed.

Ginny initial charge = $80, Bob initial charge =$60 For the initial fee, Bob charges less than Ginny.
What is unit rate?
A unit rate is the cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.
Given that Ginny charges by uses the function f(x)=60x+80 where x represents the number of hours of labour.
Ginny initial charge = $80

The gravitational potential energy gained by the group of skydivers before jumping is 4,410 kJ.
Explain the term Gravitational Potential Energy?The energy that an item has or acquires when its location changes as a result of being in a gravitational field is known as gravitational potential energy. Gravitational potential energy can be defined as an energy that has a connection to gravitational force or gravity.Gravitational Potential Energy (GPE) is estimated as;
GPE = m×g×h
In which
m = mass of parachuting outfit (kg)
g = acceleration due to gravity (m/s²)
h = height (meters)
Put the values in the formula.
GPE = 90× 9.8× 5000
GPE = 4,410,000 joules
GPE = 4,410 kJ

What do you mean by similar figures?
Two figures are said to be similar if they share the same shape. Congruent objects are those that are precisely the same size and shape.
The term "similar figures" refers to two figures that share the same shape but differ in size.
When two figures are comparable, the sign ‘∼’ is used to indicate that they are.

Shakira bowled 4 games.
Step-by-step explanation:
If Shakira paid $3 for rent, we can subtract 3 from 21.
21-3=18.
Now, find out how much 4.50 can go into 18.
First, multiply 4.50 by 2.
4.50x2=9
Now, Since 2 games is $9, multiply 9 by 2.
9x2=18
Now that we found out that 9x2=18, we can see that Shakira bowled 4 games.

The diameter of the circle pen for the sheep of the farmer is 68 yards.
Explain the term circumference of the circle?The distance along a circle's perimeter is referred to as its circumference. In other words, the circumference of a circle is equal to the length of a straight line formed by opening up the circle.The space around a circle is known as its circumference. By calculating the distance required to walk around the globe, we may determine the size of the earth's circumference.The total length of the fencing used for the preparation of the fencing for sheep is 213.52 yards.
Thus,
circumference = 213.52 yards
The formula for the calculation of the circumference of circle is,
circumference = 2πr,
In which,
π = 3.14 and radius r.
Thus,
213.52 = 2πr
r = 213.52 / 2π
r = 34
Diameter = 2 x radius
Diameter = 2 x 34

Use Green's theorem and find the work that the force F performs when acting along the complete trajectory counterclockwise. The dimensions of the region R are b = 3 and d3 in ft. The force F is: F = [ay-cx ] lb; use a=2 and c=2. C, RC 0 c, d x
The work that the force F performs is -36.
How to calculate work using Green's Theorem?F = [ay - cx]
a = 2
b = 3
c = 2
d = 3
Green's theorem is theorem about the relationship between a integral line on a simple closed curve C and a double integral of a plane D bounded by C. So, from Green's Theorem we get,
∫Pdx + Qdy = ∫∫([tex]\frac{\partial Q}{\partial x}[/tex]-[tex]\frac{\partial P}{\partial y}[/tex])dA
Put the a and c value into force F equation. So,
F = [2y - 2x]
From this, we get
P = 2y
Q = -2x
[tex]\frac{\partial P}{\partial y}[/tex] = 2
[tex]\frac{\partial Q}{\partial x}[/tex] = -2
So, the integral formula become
∫∫([tex]\frac{\partial Q}{\partial x}[/tex]-[tex]\frac{\partial P}{\partial y}[/tex])dA = ∫∫(-2-2)dA
= -4 dA
Next, we calculate the work
Work = -4 × b × d
= -4 × 3 × 3
= -36
Thus, the work is -36 for the force F performs.

The circumference of a circle is 22pi cm. What is the area, in square centimeters?
Answer:
Area = 121pi sq cm
Step-by-step explanation:
Circumference is the distance around the circle. The formula for circumference is:
C = pi•d
The question has the info in it that the circumference is 22pi.
C = 22pi
remember,
C = pi•d this means that the circle has a diameter (the d in the formula is diameter) 22cm.
The radius is half the diameter. The diameter is 22cm, so the radius is 11cm.
The formula for the area is:
Area = pi•r^2
= pi•11^2
= pi•121
= 121pi
The area is 121pi sq cm.

Using the Pythagorean Theorem, determine the distance from point (8, −6) to the origin
Pls help asap
Step-by-step explanation:
a point on a coordinate grid always creates a right-angled triangle.
the straight distance from the origin (0, 0) is the Hypotenuse (the side opposite of the 90° angle).
the coordinate distances in x and y directions are the 2 legs.
Pythagoras :
c² = a² + b²
c being the Hypotenuse, a and b being the legs.
so,
(distance from origin)² = x² + y²
because the x, y coordinates are the coordinate distances from the origin in x and in y direction.
distance² = 8² + (-6)² = 64 + 36 = 100
distance = sqrt(100) = 10
the point is 10 units apart from the origin.
