In a certain large lake 30% of the fish are thrown back because they are too
small. Consider catching 20 fish from the lake. Assume that the fish you

fish in the lake. Let Y= the number of fish that you throw back because they
are too small.
The likelihood of precisely x successes on n further trials in an experiment with two possible outcomes is known as a binomial probability.
What is meant by Binomial probability?The possibility that a variable would take one of two independent values under a particular set of parameters or assumptions is expressed by the statistical distribution known as the binomial distribution.
The utilization of this distribution pattern in statistics has ramifications for finance and other areas as well. It can help banks decide how much money to lend and how much cash they should hold in reserve as well as the risk that a specific borrower will default. In the insurance sector, it's also employed to calculate policy premiums and evaluate risk.
The likelihood of precisely x successes on n further trials in an experiment with two possible outcomes is known as a binomial probability (commonly called a binomial experiment).
Yes, this is an example of a binomial situation. The probability of a specific number of success outcomes from repeated or numerous incidents can be determined using this method.
Success {Event P} small fish, with prob = 30% = 0.3 .
Failure {Event Q} large fish, with prob = 70% = 0.7
Number of trials = 20. Let r be number of small fishes out of 20 fishes.
Binomial probability = [tex]$$N c r . (P)^r . (Q)^ {(n-r)[/tex]
P( 5 small fish out of 20) = 20c5 [tex](0.30)^5 (0.70)^{15[/tex]

A particle (charge = +40 uc) is located on the x axis at the point x = -20 cm, and a second particle (charge = -50 uc) is placed on the x axis at x = +30 cm. What is the magnitude of the total electrostatic force on a third particle (charge = -4. 0 uc) placed at the origin (x = 0)?.
The total electrostatic force on the third particle will be 56 N in -x direction.
q1 = +40 μC, x1 = -20 cm = - 0.2 m
q2 = -50 μC, x2 = 30 cm = 0.3 m
q = -4 μC, x = 0
We know that, the electrostatic force between two charges
F = kQ1Q2/d²
k = 9 × 10⁹ Nm²/C²
here, d: distance between two charges
F1 = k(40×10⁻⁶)(-4× 10⁻⁶)/(0.2)²
F1 = - 36 N {(-) sign shows the force is attraction force}
so, the direction of F1 on q is -x-direction
F2 = k(-50×10⁻⁶)(-4× 10⁻⁶)/(0.3)²
F2 = 20 N {Repulsive force because both particles are having negative charge}
so, the direction of F2 on q is in the -x-direction
So Total force F = F1+F2 = 20+36 = 56 N
Therefore, the total electrostatic force on the third particle will be 56 N in the -x direction.

What is inverse function?
A function takes in values, applies specific operations to them, and produces an output. The inverse function acts, agrees with the outcome, and returns to the initial function.
The output of a function is returned by the inverse function, which also returns the initial value.
Consider the inverse relationship between the functions f and g: f(g(x)) = g(f(x)) = x. The initial value is fetched via a function that is its inverse.
Here the given function f(x) = [tex]\frac{x+3}{2}[/tex]
a) Put x= 2 into f(x) then
=> f(2) = [tex]\frac{2+3}{2}[/tex]
=> f(2) = [tex]\frac{5}{2}[/tex]
b) Now to find inverse function , take y=f(x) then
=> y = f(x)
=> y = [tex]\frac{x+3}{2}[/tex]
Now interchange x and y and solve for y then,
=> x = [tex]\frac{y+3}{2}[/tex]
=> 2x= y+3
=> y = 2x-3
Then y = [tex]f^{-1}(x)[/tex]
=> [tex]f^{-1}(x)[/tex] = 2x-3.
c) Now put x=12 into [tex]f^{-1}(x)[/tex] = 2x-3 then

The distribution of density along one axis will be equal to that on all the axis as the density is uniform and center of the sphere is at the origin.
A sphere is a geometrical object that resembles a two-dimensional circle in three dimensions. In three-dimensional space, a sphere is a collection of points that are all located at the same r-distance from a single point.
The particle P is attracted to a solid sphere of uniform density and radius R by a gravitational force of attraction F1. The particle is located 2R from the sphere's center.

A formula declares that two things are equal. The equals sign "=" will be present. According to that formula, the left (x + 2) is equal to the right (6)
The statement "this equals that" is analogous to an equation.
A variable is a symbol used to represent an unknown number. Typically, a letter like x or y is used.
A Constant is a number that exists by itself.
When multiplying a variable, a coefficient is used (4x means 4 times x, so 4 is a coefficient)
In reality, variables have a coefficient of 1 when there isn't a number next to them (x is really 1x)
Given the problem R+7=-6+5r+8-3r

What is inverse function?Inverse is a function that is severs to undo another to the function.thag is produces y,then putting y and into the inverse of f of the produces the output x.
To find the inverse of h(t), we need to first solve for t in the equation h(t) = 16t^2 + 144. This can be done by finding the roots of the equation, which can be done by setting the equation equal to zero and using the quadratic formula,
t = ±√(h(t) - 144)/16
Since h(t) is a quadratic function, the inverse of h(t), h-1(t) will also be a quadratic function. Therefore, h-1(t) can be written as:
h-1(t) = ±√(t - 144)/16
To show that h(t) and h-1(t) are inverses, we can plug in a known value, such as t = 10, and check that the results of both equations are equal.
h(10) = 16(10)^2 + 144 = 272
h-1(272) = ±√(272 - 144)/16 = ±√(128)/16 = 10
