All possible samples of size n are selected from a population and the mean of each sample is determined. What is the mean of the sample means?
Answer:
The population mean
Step-by-step explanation:
Sample Mean is the mean of of the selected samples while the population Mean is the mean of all the population. The mean of the sampling distribution of the sample mean is equal to the mean of the original distribution (that is the sample mean is equal to the population mean).
The mean of the sample means is always approximately the same as the population mean

We are told that the coordinates of the image are of the formula:
P'(x-2 , y-3) where x and y are the actual points and x-2 and y-3 are the reflections
Finding the coordinates of point A:
We are given that the coordinates of reflection of A are: A'(-4 , 3)
we also know that reflected point follow the formula: P'(x-2 , y-3)
So, the points of A'(-4 , 3) follow the formula P'(x-2 , y-3)
So, their respective x and y coordinates will be equal
Hence,
x - 2 = -4
x = -2 [adding 2 on both sides]
Also,
y - 3 = 3
y = 6 [adding 3 on both sides]
Therefore, the coordinates of A are A(-2,6)
Finding the coordinates of B:
We are given the coordinates of B' are B'(-4 , 2)
So,
x - 2 = -4
x = -2 [adding 2 on both sides]
also,
y-3 = 2
y = 5 [adding 5 on both sides]
Therefore, the coordinates of B are: B(-2,5)
Finding the coordinates of C:
We are given that the coordinates of reflection of C are: C'(-2,3)
Using the general formula given in the question:
x - 2 = -2
x = 0 [adding 2 on both sides]
y - 3 = 3
y = 6 [adding 3 on both sides]
Therefore, the coordinates of C are: C(0,6)
Finally, the coordinates of A, B and C are:
A(-2,6) , B(-2,5) , C(0,6)

Reflecting the pre-image along the x-axis
To reflect along x-axis, we multiply the y-coordinate by -1
Coordinates of the pre-image:
A(-2,6) , B(-2,5) , C(0,6)
Coordinates of points reflected along the x-axis:
A(-2,-6) , B(-2,-5) , C(0,-6)

Factor -4 out of -8d + 20
Answer:
2d-5
Step-by-step explanation:
Take out or divide everything in the expression by -4
So, (-8d+20) ÷ -4 = 2d-5
To check your answer, multiply:
-4 × (2d-5) = -8d+20
The linear expression in one variable -8d + 20 can be written as -4(2d - 5) after factoring -4 from it.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The linear expression in one variable is:
= -8d + 20
Here d is the variable
Taking common as - 4 from the linear expression:
= -4(2d - 5)
Thus, the linear expression in one variable -8d + 20 can be written as -4(2d - 5) after factoring -4 from it.

La proporción de niños y niñas en la obra escolar es de 5 a 8. Hay 32 niñas que participan en la obra. ¿Cuántos niños participan en la obra escolar?
Answer:
Total children = 52
Step-by-step explanation:
The question says that "The ratio of boys to girls in the school play is 5 to 8. There are 32 girls participating in the play. How many children participate in the school play? "
Let there are 5x boys and 8x girls in a school play.
Total no of girls participating in the play = 32
ATQ,
8x = 32
x = 4
Boys = 5x
= 5(4)
= 20
Total children = boys + girls
= 20 + 32
= 52
Hence, there are 52 children participating in the school play.

Answer:
x = √66
Step-by-step explanation:
In a geometry like this, the right triangles are all similar. Then the length of the long side to the hypotenuse is ...
6/x = x/(6+5)
6·11 = x²
x = √66
_____
Additional comment
The relation g=√(ab) gives the geometric mean (g) of the two numbers 'a' and 'b'. In this geometry, there are three geometric mean relationships.
long side = geometric mean(long segment, hypotenuse) . . . x = √(6·11)
short side = geometric mean(short segment, hypotenuse) . . . y = √(5·11)
altitude = geometric mean(long segment, short segment) . . . BD = √(6·5)

A bridge hand is made up of 13 cards from a deck of 52. Find the probability that a hand chosen at random contains at least .
Answer:
10%
Step-by-step explanation:
Since the question is not complete, I will be solving for probability of 3 9s
To solve this, we would be using the principle of combination, and thus
A deck of 52 hours has 4 nines, the probability that it contains at least 3 9s is mathematically represented by the equation.
P ( x ≥ 3 ) = ( 48 C 10 · 4 C 3 ) / ( 52 C 13 ) + ( 48 C 9 · 4 C 4 ) / ( 52 C 13 )
Remember I told us were going to be using the principle of combination. Well then
nCr = n!/r!(n - r)!
Now, applying the above stated formula to the equation, we have
48C10 = 48!/10!(38!)
4C3 = 4!/3!(1!)
52C13 = 52!/13!(39!)
48C9 = 48!/9!(39!)
4C4 = 4!/4!(0!)
Solving for each independently, we find that
= 0.0412 + 0.588 = 0.1

explain a process to find at least three decimals that are in between two other decimals then provide an example. (Choose two decimals, then use your process to find 3 other decimals that are in between the ones you choose)
Answer:
Between 2.5 and 3.5, you have 2.56, 3.2376, and 3.001
Step-by-step explanation:
THE PROCESS:
If you wish to find 3 decimals that are in between 2 other decimals, first select 2 decimals that have some distance between them (one being larger in value than the other).
The number of decimals found between them will depend on the magnitude of the difference between the initial 2 decimals.
You can then pick out 3 or more decimals between these 2 numbers.
THE EXAMPLE:
2.5 and 3.5
The difference between these two values is 1. Many decimals can be found within this single unit.
2.56 is a decimal, 3.2376 is another decimal, 3.001 is a decimal too.
All these decimals fall between 2.5 and 3.5 above.
You should find many more decimals just between these two numbers.
Once the value of the decimal is greater than 2.5 and less than 3.5, it falls within this range.
It could be a number in one decimal place, a number in two decimal places, a number in three decimal places, and so on.

Given: x + y = 10.
If x = -21, what is y?
31
11
-31
Answer:
y is 31
Step-by-step explanation:
we need to substitute first
x + y = 10
x= -21 so...
-21 + y = 10
now we need to add 21 on both sides of the equation, we are adding because 21 because we want that 21 gone, and it's the oppisite of subtracting
-21 + 21 + y = 10 + 21
0 + y = 10 + 21
y= 31
Check:
x+y=10
-21 + 31= 10
10 = 10 correct!

A sampling distribution is the probability distribution of _____. Group of answer choices a population parameter a sample statistic an observation that is randomly selected from the population a sample
Answer:
"a Sample Statistic"
Step-by-step explanation:
A sampling distribution is defined as the probability distribution of "a statistic" drawn from a large number of samples gotten from a specific population. In order words, it is a sample statistic.
Thus, the correct answer is "a Sample Statistic"
The sampling distribution is the probability of a particular report based on random sampling; it displays the most likely values of various sample means
Sampling distribution:It is a probability distribution of data mining, which is the process of analyzing larger samples gathered from a given population.
In this, a particular population is the distribution of frequencies of a variety of possible outcomes for a population statistic.
It is the distribution of the probability for a statistic is generated from a large number of samples gathered from a certain population.
Therefore, "The sampling distribution is the probability of a particular report based on random sampling; it displays the most likely values of various sample means".

Someone please help me
Answer:
The third option
Step-by-step explanation:
If you plug -4 in for x in the first option, you would get 12 + which is 14 and
14 ≠ 5.
If you plug in -4 for the second option you would have -0.75 times -4 which is 3 and 3 plus 8/3 would not give you a whole number so it is not equal to 5.
If you plug in -4 to the third option you would get -4 times -0.75 which is 3 and 3 + 2 = 5. But to check the rest of the numbers you would plug in 0 for x and get -0.75 times 0 is 0 and 0 + 2 = 2.
For the last option, just to eliminate all other options, if you plug in -4 for x you would have 2 times -4 which is -8 and -8 - 0.75 would not be a whole number so it could not be 5.
