From the sampling distribution, the correct answer is: Both the center will remain the same, but the spread will decrease.
How is the center and spread of the sampling distribution different from the first experimentThe center of the sampling distribution will remain the same, which is the expected proportion of even numbers showing on a single roll of the die, which is 1/2 or 0.5. This is because the probability of getting an even number on a single roll of the die does not change with the number of rolls in the experiment.
However, the spread of the sampling distribution will decrease as the number of rolls increases. This is because the larger the sample size, the more precise our estimate of the proportion of even numbers showing on each roll of the die will be. With more rolls, we will have a better idea of the true proportion of even numbers that the die produces.

The slope of the line below is -4. Which of the following is the iS point-slope
form of the line?
\ (2, -8)
O A. y+ 8 = -4(x-2)
O B. y+ 2 =-4(x-8)
• C. y-8 = -4(x+ 2)
• D. y- 2=-4(x+ 8)
Correct option is A, the iS point-slope form of the line is y+ 8 = -4(x-2). A straight line's equation can be written as both a point slope form and a slope intercept form.
What does "point-slope form of the line" refer to?A line equation written using a single line point and the slope of the line is the simplest definition of the term "point-slope form." The slope is expressed in point form as the ratio of the change in y values to the change in x values, also known as the rise over run (x, y).
The point slope form is useful when there is a slope and one or more points are present. Standard form is often easier to employ while doing algebraic computations. Depending on our needs or our level of expertise, we can alter the form of an equation. Both the point slope form and the slope intercept form can be used to express the equation for a straight line. The point slope form highlights any point on the line as well as the slope. The slope and y-intercept of a line are only shown in slope intercept form.
Given,
the slope of line = - 4 and point = (2,-8)
The equation of line = y - yo = m (x - xo)
where m = slope and x,y are coordinates
y + 8 = - 4 (x - 2)
y + 8 = - 4x + 8
y = - 4x
Therefore, the correct answer is option A, y+ 8 = -4(x-2)

The length of side AC is
The area of triangle ABC is
square units.
Answer:
The length of side AC is 5 units.
The areas of triangle ABC is 10 square units.
Step-by-step explanation:
From point A (1,3) to point C (1,-2) is 5 units
To check this:
3 - (-2) = 3 + 2 =5
We're subtracting since the point went down (from positive 3 to negative 2)
Now for the area:
Area formula for a triangle: \(\frac{1}{2}\)bh = \(\frac{1}{2}\)⋅b⋅h
We already found the height (length) : 5
The base is from point C (1,-2) to point B (5,-2), which is 4 units
To check this:
5 - 1 = 4
Now that we have found the base and height, Let's solve:
\(\frac{1}{2}\)⋅4⋅5 = \(\frac{1}{2}\)⋅20 = 10
Our area is 10 square units.

explain why it takes more 1/9s than 1/6s to make a fraction equivalent to 1/3
Answer:
1/9 is smaller than 1/6, so it takes more amounts of 1/9 to make make a fraction equal to 1/3
It takes more 1/9 than 1/6 to make a fraction equivalent to 1/3.
What is a fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
To make a fraction equivalent to 1/3, we need to multiply both the numerator and the denominator by the same non-zero constant. Let's call this constant "x". Therefore, the equivalent fractions are:
1/3 = (x1)/(x3)
To compare how many 1/9s and 1/6s are needed to create this fraction, we need to find the value of "x" that will make the denominators of 1/9 and 1/6 equal to the denominator of 1/3, which is 3.
For 1/9, we can find x as follows:
1/9 = (x1)/(x9)
Multiplying both sides by 3, we get:
3/9 = (x3)/(x9)
Simplifying, we get:
1/3 = x/9
Multiplying both sides by 9, we get,
x = 3
Therefore, to make a fraction equivalent to 1/3 using 1/9, we need to multiply both the numerator and denominator by 3.
Now let's look at 1/6. We can find x as follows:
1/6 = (x1)/(x6)
Multiplying both sides by 2, we get:
2/12 = (x2)/(x12)
Simplifying, we get:
1/6 = x/12
Multiplying both sides by 12, we get:
x = 2
Therefore, to make a fraction equivalent to 1/3 using 1/6, we need to multiply both the numerator and denominator by 2.

Linear sequence of 35/100,5/10,65/100
The linear rule for the sequence is f(n) = 7/20 + 3/20(n - 1)
Finding the linear rule for the sequenceFrom the question, we have the following parameters that can be used in our computation:
35/100,5/10,65/100
In the above sequence, we can see that 15/100 is added to the previous term to get the new term
This means that
First term, a = 35/100
Common difference, d = 15/100
The nth term is then represented as
f(n) = a + (n - 1) * d
Substitute the known values in the above equation, so, we have the following representation
f(n) = 35/100 + 15/100(n - 1)
So, we have
f(n) = 7/20 + 3/20(n - 1)

A dilation has center (0,0). Find the image of the point B ( 5/3, -7/2) for the scale factor 1/3
=======================================================
Explanation:
Since the center of dilation is (0,0), we multiply each coordinate of point B by the scale factor 1/3.
The coordinates of point B are x = 5/3 and y = -7/2
So we have
(1/3)*x = (1/3)*(5/3) = (1*5)/(3*3) = 5/9 as the new x coordinate
and
(1/3)*y = (1/3)*(-7/2) = (1*(-7))/(3*2) = -7/6 as the new y coordinate
The point (5/3, -7/2) moves to (5/9, -7/6)

In △ABC,a=14 , b=17 , and c=22 . Find m∠A . law of sines 4 A. 49.4 B. 39.5 C. 55.2 D. 50.45
The correct option is not available among the choices provided (A. 49.4, B. 39.5, C. 55.2, D. 50.45).
To find the measure of angle A in triangle ABC using the Law of Sines, we can use the formula:
sin(A)/a = sin(B)/b = sin(C)/c
Given that a = 14, b = 17, and c = 22, we can substitute these values into the formula:
sin(A)/14 = sin(B)/17 = sin(C)/22
To find angle A, we need to solve for sin(A) and then take the inverse sine (arcsin) of that value.
First, let's find sin(B) using the given information:
sin(B)/17 = sin(A)/14
sin(B) = (17 * sin(A))/14
Next, let's find sin(C):
sin(C)/22 = sin(A)/14
sin(C) = (22 * sin(A))/14
Since the sum of angles in a triangle is 180 degrees, we can calculate angle C:
angle C = 180 - angle A - angle B
Now, we can substitute the expressions for sin(B) and sin(C) into the equation:
(22 * sin(A))/14 = (17 * sin(A))/14 + sin(B)
To solve for sin(A), we can multiply both sides of the equation by 14:
22 * sin(A) = 17 * sin(A) + 14 * sin(B)
22 * sin(A) - 17 * sin(A) = 14 * sin(B)
5 * sin(A) = 14 * sin(B)
sin(A) = (14/5) * sin(B)
Finally, we can take the inverse sine (arcsin) of sin(A) to find the measure of angle A:
A = arcsin((14/5) * sin(B))
Now, since the values of angles B and C are not provided, it is not possible to directly determine the measure of angle A using the given information.
