Upper = 0.3441888
What is sampling distribution ?The probability distribution of a statistic acquired from a bigger sample size taken from a certain population is known as the sampling distribution. The frequency distribution of a variety of possible outcomes for a population statistic makes up the sampling distribution of a specific population. A population is the total group from which a statistical sample is taken in statistics. An complete collection of individuals, things, occasions, medical visits, or measures can all be referred to as a population. Thus, a population may be defined as an overall observation of persons that have been categorized according to a common characteristic.

Which of the following values are solutions to the inequality 3 − 4 x ≥ − 3 ? 3−4x≥−3?
The values in the solution set of the inequality are values that do not exceed 0
How to determine the values that are solutions to the inequality?The inequality expression is given as
3 − 4 x ≥ − 3
Rewrite the expression properly.
So, we have
3 − 4x ≥ −3
Add 3 to both sides of the inequality.
So, we have
3 + 3 − 4x ≥ −3 + 3
Evaluate the like terms
So, we have
− 4x ≥ 0
Divide both sides by -4
x ≤ 0

Which letter is at coordinate position (9, 5)?
OA. Y
OB. R
OC. F
OD. Q
The point R has an abscissa 9 and ordinate 5
is c=3.75x proportional
Answer:
No
Step-by-step explanation:
If we put x=1 in equation y=x+3.75
y=(1)+3.75
y/x=4.75
If that is proportional then y/x will be the same in each scenario
and if we put x=2 then y=(2)+3.75
y=5.27
y/x=2.875
So, it is not equal, it means that equation is not proportional.

What is circular motion ?
An object moving in a circular motion is defined as rotating while doing so. There are two types of circular motion: uniform and non-uniform. While the angular rate of rotation and speed are constant during uniform circular motion, they are not during non-uniform motion.The problem is asking to find the radius of the orbit of a satellite around a planet, given the orbital speed of the satellite.
For a satellite in orbit around a planet, the gravitational force provides the required centripetal force to keep it in circular motion, therefore we can write:
[tex]\frac{GMm}{r^{2} } = m\frac{v^{2} }{r}[/tex]
where
G is the gravitational constant
M is the mass of the planet
m is the mass of the satellite
r is the radius of the orbit
v is the speed of the satellite
Re-arranging the equation, we find
[tex]\frac{GM}{r} = v^{2}[/tex]
[tex]r = \frac{GM}{v^{2} }[/tex]

Triangle ABC lies on the coordinate plane with the vertices A(7,6), B(-3,5) and C(-6,1).
The triangle is transformed using the rule (x, y) --> (x+4, 3y) to create triangle A'B'C'.
What are the coordinates of B'?
The transformation, the coordinates of point B' become (1, 15).
The transformation rule (x, y) → (x + 4, 3y) involves shifting the x-coordinate by 4 units to the right and stretching the y-coordinate by a factor of 3. To find the coordinates of B' after applying this rule, we take the coordinates of point B(-3, 5):
x-coordinate of B' = x-coordinate of B + 4 = -3 + 4 = 1.
y-coordinate of B' = y-coordinate of B * 3 = 5 * 3 = 15.
Therefore, after the transformation, the coordinates of point B' become (1, 15). This means that B' is located 4 units to the right of B along the x-axis and its y-coordinate is three times that of B. The transformation has shifted and stretched the original triangle, resulting in a new position for point B'.

Select the correct answer from each drop-down menu. what is the end behavior of function h? as x approaches negative infinity, approaches . as x approaches positive infinity, approaches .
Because the variable has an even power, we will see that:
As x approaches -∞, h(x) approaches -∞
As x approaches ∞, h(x) approaches -∞.
Here we have h(x) = -4x^2 + 11
Notice that the variable is squared, this means that the sign does not matter, the outcome of:
-4x^2 will always be negative. So in both ends (when x tends to infinity and negative infinity), we will have the same end behavior.
When we take that limit, -4x^2 will just tend to negative infinity, then in both cases, the function tends to negative infinity.
So we have:
As x approaches negative infinity, h(x) approaches negative infinity.
As x approaches positive infinity, h(x) approaches negative infinity.

a trapezoid was transformed on a coordinate grid using the rule (x, y) → (–x, y). which of the following describes this transformation?
reflect over x axis transformation represents this rule (x, y) → (–x, y).
How to find the type of transformation?Make a coordinate plot using squared paper.
An illustration.
take the coordinate points (2,3) and (-3,-2)
They are reflected in the x-axis.
The results that you should get are as follows.
(2,-3) and (-3,2)
The y-coordinate is the opposite of the original position, while the x-coordinate is unchanged.
This can be described generally as (x, y) → (–x, y).
When a point is reflected across the X-axis, its X-coordinate stays constant. On the other hand, the Y-coordinate is altered to the opposite sign.
The point (x,y) is therefore reflected across the X-axis as (x,-y).It is known as a reflect over x axis transformation.

Put the following equation of a line into slope-intercept form, simplifying all fractions.
20x+4y=8
the answer for the given question is slope is -5 and y- intercept is 2.
The slope intercept form of a straight line is one of the most common ways to represent a line's equation. When given the slope of a straight line and the y-intercept, the slope intercept formula can be used to find the equation of a line (the y-coordinate of the point where the line intersects the y-axis).
The slope-intercept form is y = mx + b , where m is the slope and b is the y-intercept.
y = mx + b
Take 20x off both sides of the equation.
4y = 8 − 20x
Simplify each term by dividing it by 4y = 8 - 20x.
y = 2 − 5x
Reorder 2 and -5x.
y =−5x + 2
Therefore after simplification we get the slope as -5
