What is the binomial distribution?
The discrete probability distribution of the number of successes in a series of n independent experiments is called the binomial distribution with parameters n and p in probability theory and statistics.
Let X be the count of successes in the first n flips by A, Y the indicator that the last flip by A is also a success, and Z the count of successes in n flips by B.
Because Y is independent of X and Z, then:
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)

the height of a cylinder is increasing at a constant rate of 2 centimeters per second, and the volume is increasing at a rate of 1152 cubic centimeters per second. at the instant when the height of the cylinder is 33 centimeters and the volume is 403 cubic centimeters, what is the rate of change of the radius? the volume of a cylinder can be found with the equation v
Answer:
about 2.758 cm/s
Step-by-step explanation:
You want the rate of change of a cylinder's radius, when its height is 33 cm increasing at 2 cm/s, and its volume is 403 cm³ increasing at 1152 cm³/s.
Rate of changeThe volume of a cylinder is given by the equation ...
V = πr²h
Solving for the radius gives ...
r = √(V/(πh))
Differentiating, we have ...
[tex]r'=\dfrac{1}{\sqrt{\pi}}\left(\dfrac{1}{2}V^{-\frac{1}{2}}h^{-\frac{1}{2}}V'-\dfrac{1}{2}V^{\frac{1}{2}}h^{-\frac{3}{2}}h'\right)=\dfrac{hV'-Vh'}{2h\sqrt{\pi Vh}}[/tex]
Filling in the values V = 403, V' = 1152, h = 33, h' = 2, we have ...
r' = (33·1152 -403·2)/(2·33·√(π·403·33)) = 37210/(66√(13299π))
r' ≈ 2.758 . . . . . cm/s
The rate of change of the radius is about 2.758 cm/s.
a biologist collected 326 fern and moss samples. there were 66 fewer ferns than moss samples. how many fern samples did the biologist collect?
There are 130 fern samples did the biologist collect.
What is fern and moss samples?
In contrast to ferns, which are vascular plants, mosses are nonvascular primitive plants that produce spores. Furthermore, unlike ferns, which have a plant body that is divided into real stems, leaves, and roots, mosses have none of these features. Ferns also have circinate vernation, which is not true of mosses.
Given:
A biologist collected 326 fern and moss samples. there were 66 fewer ferns than moss samples.
Let, f denotes the number of ferns collected and
m denotes the number of mosses collected
From the given information,
m + f = 326 ..(1)
m - 66 = f ..(2)
Plug equation (2) in equation (1),
m + m - 66 = 326
2m = 326 + 66
2m = 392
m = 196
Plug m = 196 in equation (2),
f = 196 - 66
f = 130
Hence, there are 130 fern samples did the biologist collect.

What is Set Theory?
We study sets and their characteristics in the area of mathematical logic known as set theory. A set is a collection of things or a group of things. These things are frequently referred to as elements or members of a set. A set is, for instance, a group of cricket players. A set is a clearly defined collection of things or people, as we already learnt in the introduction. Numerous examples from everyday life, such as the number of rivers in India and the colors in a rainbow, can be used to relate sets.
Given,
Total no of people =116
No of people visiting any of the three places = total - people visiting none of the places
= 116 -14 = 102
No of people visiting only Gateway arch = total people visiting gateway arch - (people visiting all the three + people visiting Gateway ans museum butnot zoo +people visiting gateway and zoo butnot museum)

Similarly, people visiting only zoo = 14

Find equations of the tangents to the curve x = 9t2 + 3, y = 6t3 + 3 that pass through the point (12, 9). (enter your answers as a comma-separated list. ).
y - 9 = 1(x - 15) is the required equation for the tangent.
What are equations?Equations come in two varieties: identities and conditional equations.
All possible values of the variables result in an identity.
Only certain combinations of the variables' values make a conditional equation true.
Two expressions joined by the equals symbol ("=") form an equation.
A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.
A formula would be 3x - 5 = 16, for instance.
When this equation is solved, we discover that the value of the variable x is 7.
So, the equation of the tangent is:
First, with respect to t, differentiate the function as follows:
dx/dt = d(9t² + 6)/dt
dx/dt = 18t
Like this, we have:
dy/dt = d(6t³ + 3)/dt
dy/dt = 18t²
Now, we will obtain:
dy/dx = 18t²/18t
dy/dx = t
We know that (15, 9) occurs on the curve, so we got:
d(9t² + 6)/dt and d(6t³ + 3)/dt ⇒ t = ±1 and t = 1 ⇒ t = 1
So, (15, 9) is the slope.
y - 9 = 1(x - 15) is the equation of the tangent.
Therefore, y - 9 = 1(x - 15) is the required equation for the tangent.

What are Statistical tests?
An instrument for making quantitative judgments about a process or processes is a statistical test. The goal is to decide whether there is sufficient data to "reject" a theory or hypothesis on the process.
In the given problem the average age of the corporate executives at the three locations is being calculated, it means more than two groups are being compared. hence, The appropriate statistic test would be ANOVA.
In order to calculate the degree of freedom, we must know the no. of observations.
here, no. of observations are 15 ( 3 × 5 ) and the no. of groups are 3.

Drag statements and reasons to each row to show why the slope of the line between D D and E E is the same as the slope between E E and F F , given that triangles A A and B B are similar.
By definition of slope , we have seen that Slope = 4/3 and 4/3 = 16/12
How to find the slope of a Line?The slope of a line is basically a measure of its steepness. Mathematically, the slope is calculated as rise over run.
To find the slope, we divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. This is change in y divided by change in x.
From definition of slope, we know that;
Slope between line D and E is; Slope = 4/3
Similarly, by definition of slope, we know that;
Slope between line D and E is; Slope = 16/12

Step-by-step explanation:
Looking at the equations,
x + 4y = 10
2x + 8y = 20
If x = 2, and y = 0 then it would look something like this:
2 + (4×2) = 10
Let's apply that to the next equation:
(2×2) + (8×2) = 20
In conclusion, x = 2, y = 2
the volume of a sample of nitrogen is 6.00 liters at 35oc and 0.974 atm. what volume will it occupy at stp?
5.152 L volume will it occupy at STP.
What is ideal gas law?
The equation of state for an ideal gas, in theory, is known as the ideal gas law. Even though it has a number of shortcomings, it provides a good approximation of the behavior of several gases under various circumstances. Theoretical point particles that move randomly and only collide in elastic ways make up an ideal gas.
Using the ideal gas equation PV=nRT, where n is the number of moles, it is possible to determine the volume that will be present at STP as follows.
n= PV/RT
p=0.974 atm
V=6.0 L
R = 0.0821 L.atm/k.mol
T= 35 +273= 308k
n= (0.974 atm x 6.0 L)/( 0.0821 L.atm/k.mol x 308 k)= 0.178 moles
STP 1 mole= 22.4 L what obout 0.23 moles
=22.4 x0.178moles/ 1moles =5.152 L
Hence, 5.152 L volume will it occupy at STP

The square on the right is a scaled copy of the square on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
The scale factor of the figure of the two squares is 1.5
How to find the scale factorThe scale factor is determine using division
The formula involve:
let the scale factor be r then we say
area of square A * r = area of square B
8 * 8 * r = 12 * 12
64r = 144
r = 144 / 64
r = 1.5
using the dimensions
8r = 12
r = 12 / 8
r = 1.5
