In two common species of flowers, A and B, the proportions of flowers that are blue are papa and pbpb , respectively. Suppose that independent random samples of 50 species-A flowers and 100 species-B flowers are selected. Let pˆap^a be the sample proportion of blue species-A flowers and pˆbp^b be the sample proportion of blue species-B flowers. What is the mean of the sampling distribution of pˆa−pˆbp^a−p^b ?
Answers
As per the given distribution, the mean of the sampling distribution is Pa - Pb
The term mean in distribution refers adding all numbers in the data set and then dividing by the number of values in the set.
Here we have given that the proportions of flowers that are blue are papa and pbpb , respectively.
And we need to find the mean of the sampling distribution
While we looking into the given question the mean of a sampling distribution is the population mean from which values are sampled.
Here for a population of mean µ, then the mean of the sampling distribution is μx
=> μα = μ
Here from the given parameters, let us consider that then independent random samples of 50 species-a flowers and 100 species-b flowers are selected
Then it can be written as Pa refers sample proportion of blue specie - a and Pb refers sample proportion of blue specie - b
Therefore, the resulting mean is Pa - Pb

Answer:
i think its =y7x-4
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
The slope is going to be associated with an “x” and we know that the slope equals -7 so it’s important to add the NEGATIVE sign.
Also, the x-intercept is POSITIVE. It won’t be A because their x-intercept is negative. It won’t be C because their slope is positive. It won’t be D. because they didn’t put -7 as a slope.

c) inside the cone y= x +z 2
Hint: you may want to use spherical-like coordinates, where the roles of x,y and z are permuted.
Answers
Answer:
Read carefully below
Step-by-step explanation:
We can use spherical coordinates to represent the points on the sphere. These coordinates are typically denoted as (r, θ, φ), where r is the radius of the sphere, θ is the polar angle, and φ is the azimuthal angle.
In order to find a parametric representation of the part of the sphere that lies inside the given cones, we can use the following approach:
First, we need to find the intersection of the sphere and the cone. This is the set of points that satisfy the equations of both the sphere and the cone.
Then, we can use spherical coordinates to represent these points on the sphere.
Finally, we can use these spherical coordinates as parameters in a parametric equation of the form x = x(r, θ, φ), y = y(r, θ, φ), z = z(r, θ, φ) to represent the points on the part of the sphere that lies inside the cone.
Let's use this approach to find a parametric representation of the part of the sphere that lies inside the cone z = 3(x^2 + y^2) in the first case.
To find the intersection of the sphere and the cone, we need to solve the following system of equations:
x^2 + y^2 + z^2 = 16 (equation of the sphere)
z = 3(x^2 + y^2) (equation of the cone)
Substituting the second equation into the first equation, we get:
x^2 + y^2 + 9(x^4 + y^4) = 16
This equation represents an ellipse in the xy-plane. We can use the parametric equations of an ellipse to represent the points on this ellipse:
x = a * cos(t)
y = b * sin(t)
where a and b are the semi-major and semi-minor axes of the ellipse, respectively, and t is a parameter that varies from 0 to 2π.
We can now use spherical coordinates to represent the points on the part of the sphere that lies inside the cone. We can let r be the radius of the sphere (r = 4), θ be the polar angle (0 ≤ θ ≤ π), and φ be the azimuthal angle (0 ≤ φ ≤ 2π).
The parametric equations of the sphere in spherical coordinates are:
x = r * sin(θ) * cos(φ)
y = r * sin(θ) * sin(φ)
z = r * cos(θ)
Substituting the equations for x and y from the ellipse into the equations for x and y from the sphere, we get:
x = 4 * sin(θ) * cos(φ) = a * cos(t)
y = 4 * sin(θ) * sin(φ) = b * sin(t)
z = 4 * cos(θ) = 3(x^2 + y^2) = 3(a^2 * cos^2(t) + b^2 * sin^2(t))
We can solve for a and b in terms of r and θ:
a = 4 * sin(θ)
b = 4 * sin(θ)
Therefore, the parametric equations for the part of the sphere that lies inside the cone z

Submit Question
Answers
A function is an expression that defines a relationship between an independent variable and a dependent variable.
The number of bacteria colonies after 2 hours is 220.
What is a function?It is an expression that defines a relationship between an independent variable and a dependent variable.
We have,
P(t) = 4t² + 27t + 150
Where t = time
P(t) = population of a slowly growing bacteria colony after a particular time
The growth rate after 2 hours:
P(2) = 4 x (2)² + 27 x 2 + 150
P (2) = 16 + 54 + 150
P (2) = 220
Thus the number of bacteria colonies after 2 hours is 220.

In figure, determine the character of the collision. The masses of the blocks, and the velocities before and after are given. The collision is A. perfectly elastic B. Partially inelastic C. Completely inelastic D. This collision is not possible
Answers
Since the velocity of both blocks after the collision is the same, the collision is completely inelastic, meaning that kinetic energy is not conserved.
The figure shows two blocks of masses m1 and m2 colliding with velocities u1 and u2 before the collision, and velocities v1 and v2 after the collision. Since the velocities of both blocks after the collision are the same (v1 = v2), the collision is completely inelastic. This means that kinetic energy is not conserved; some energy is transferred to other forms such as heat or sound. In a perfectly elastic collision, the velocities of the two blocks after the collision would be different and the kinetic energy would be conserved. In a partially inelastic collision, the velocities after the collision would be different but the kinetic energy would not be completely conserved. Therefore, the character of this collision is completely inelastic.

C. The inverse relation must be a straight line. The inverse relation must be a straight line.
D. The inverse relation must pass the vertical line test.
Answers
the correct option is D:
" The inverse relation must pass the vertical line test."
Which is one condition that must be present for an inverse relation to be a function?
Remember that a relation is only a function if each value in the domain is only mapped into a single value in the range.
All functions need to pass what is called the "vertical line test" this means that if you draw a vertical line on the graph of the function, the vertical line can intersect the graph at most one time. If the vertical line intercepts the graph two or more times, then it is not a function.
From this we conclude that the correct option is D:
" The inverse relation must pass the vertical line test."

Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die.

Answer:
A=82°
a= 67.4

Step-by-step explanation:
For A
A+B+C =180°
A= 180-(B+C)
A= 180-(36+62)
A= 189-(98)
A= 82°
For a
a/sinA= b/sinB
a/sin82= 40/sin36
a= (40*sin82)/sin36
a=( 40*0.9903)/0.5878
a=67.39
Approximately = 67.4
For c
c/sinC= b/sinB
c= (sinC*b)/sinB
c= (sin62*40)/sin36
c =(0.8829*40)/0.5878
c = 60.08
Approximately = 60.1
