The equation reads: y = 1/3x - 4/3.
Describe Line.The points that make up a line can be extended endlessly in opposite directions. Two points along the same line are referred to as collinear points.
The slopes are the same if two lines are parallel to one another.
Consequently, line h's slope would be equal to line g's 1/3.
All that is left to do is plug the points into the formula to determine the y-intercept.
2 = 1/3(10) + b
2 = 10/3 + b
2 - 10/3 = b
2-10/3 = b
-4/3 = b
Hence, the equation for h is y = 1/3x - 4/3.

graph this function f(x) = -7x - 64
The graph of the function f(x) = -7x - 64 will be a straight line.
A function may be defined as an expression in which for every input variable x there is only one output variable y. The input variable is called independent variable and output variable is called dependent variable. The function f(x) = -7x - 64 is in the form of linear equation in one variable as it is expressed in the form of f(x) = ax + b where a, b are coefficients and x are the independent variable. When we plot this function, we compare it from the slope intercept form of line that is y = mx + c where m is slope and c is y intercept. It will be a straight line having a negative slope which is equal to -7 and the y intercept will be equal to -64 as compared from slope intercept form. The graph of the function plotted is attached below. For x intercept we put f(x) = 0, so we get x intercept equal to -64/7. Coordinates of x intercept is (-64/7, 0) and that of y intercept is (0, -64).

A simple random sample of size n is obtained from a population that is skewed left with and. Does the population need to be normally distributed for the sampling distribution of to be approximately normally distributed? why? what is the sampling distribution of ?.
Normal distributions are frequently employed in the natural and social sciences to describe real-valued regressors with uncertain distributions, normal distributions are essential to statistics.
The central limit theorem is one reason they are significant.
This claim argues that, in some circumstances, the average of many samples (observations) of a random variable with finite variance and mean is itself a random variable, whose distribution tends to become normal with an increase in sample size. Because of this, distributions of physical quantities that are meant to be the culmination of multiple separate processes, such as error margins, frequently resemble normal distributions.Only the normal distribution has additional cumulants after the first two that are zero. It is also the continuous distribution with the highest level of entropy for a given mean and variance. Assuming that the mean and variance are finite, Geary has shown that the normal distribution is the only distribution in which the mean and variance calculated from a collection of independent drawings are independent of one another.The normal distribution is a form of elliptical distribution. The normal distribution is symmetric about its mean and non-zero over the whole real line. Consequently, it could not be an appropriate model for variables that are inherently positive or highly skewed, such as a person's weight or the value of a share.To learn more about normal distribution visit:

No, there is nothing wrong in the research that is done by the head of the institution. He said correct that the mean age of the full time students has declined.
Given above that a university's director of institutional research thought that the average age of full-time students was lowering. The average age of a full-time student in 1995 was 27.4 years old.
He registered all 4934 pupils for this and the average age was 27.1 years.
The fact that the inquiry concerns the average age of a full-time student makes this situation ideal. This is a trustworthy approach when the mean is calculated after accounting for all full-time students at the university.
Given that this is a left-tailed test, the hypothesis is also correct.
He rejected the null hypothesis because p = 0.0020.05.
The average age did decrease, in conclusion. The situation is ideal.
Therefore his hypothesis is absolutely correct. There is nothing wrong with it.

What is the equation of the graph?
The required equation of the graph is y = x - 1.
How can we define the slope for a given line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively. Therefore, the relationship between the change in the y-coordinate and the change in the x-coordinate is provided by the formula m = change in y/change in x = Δy/Δx, where "m" is the slope of a line.
Mathematically, slope of a line = m = (y₂ - y₁)/(x₂ - x₁)
What is the y-intercept for a given line?
When a graph crosses the y-axis, that location is known as the y-intercept. It is, in other words, the value of y at x=0.
What is the general equation of a line?
The equation for a standard line is y = mx + c, where m is the slope and c is the y-intercept.
Given, the line passes through the points (-1, 0) and (0, 1).
Also, the y-intercept for the line = c = -1
Now, using the formula established in the literature, we get:
slope = m = (y₂ - y₁)/(x₂ - x₁) = (1 - 0)/(0 - (-1)) = 1/1 = 1
y-intercept = c = -1
Therefore, equation of the standard line is y = mx + c, thus y = (1*x) + (-1)
Thus, the required equation of the graph is y = x - 1.

How many pounds of apples will he get if he goes to David’s orchard?
Answer:
David's orchid: 20 +x
Pam's orchid: 25 + 0.75x
Step-by-step explanation:
Framing linear equations:
David's apple orchid:Cost of first 10 pounds = 10 * 2 = $ 20
Let the weight of additional apples picked = x pounds
Cost of 'x' pounds = 1 * x = $ x
Total cost = cost of first 10 pounds + cost of additional 'x' pounds
= 20 + x
Pam's orchid:Entry fee = $ 10
Cost of first 10 pounds = 10 * 1.50 = $ 15
Cost of 'x' pounds = 0.75*x = 0.75x
Total cost = Entry fee + cost of first 10 pounds + cost of additional 'x' pounds
= 10 + 15 + 0.75x
= 25 + 0.75x

The preimage of M(-3,-5) under a translation is M'(6, -1).
Using the same translation, find the image of B', if B is (3,-2).
B'
By using the same translation applied to point M, the image of point B' is equal to (12, 2).
What is a translation?In Geometry, a translation can be defined as a type of transformation which moves every point of a geometric figure (object) in the same direction, as well as for the same distance.
Since the x-coordinate moved from a negative to a positive sign, we know that point M was translated to the right and then shifted down because it moved from a negative to a negative sign on the y-coordinate.
Next, we would determine the translation rule that was applied to point M:
(x, y) → (x + n, y - z)
-3 + n = 6
n = 6 + 3
n = 9.
-5 - z = -1
z = -5 + 1
z = -4
Now, we can determine the image of B':
(x, y) → (x + n, y - z)
Point B (3, -2) → Point B' (3 + 9, -2 - (-4)) = (12, 2).

Two parallel lines are cut by a transversal. Suppose <1 and <2 are alternate interior angles and that m<1=4(x+2) and m<2=2x+24. What is the m<2?
The value of m∠2 will be equal to 40°.
Transversal may be defined as a line which cuts two different lines which lie on the same plane at two different points. Alternate interior angles may be defined as the angles which are formed when a transversal cut the two different lines. These angles lie on the interior of the parallel lines, but they are on the opposite side of the transversal. If two parallel lines are cut by a transversal, then their alternate interior angles are equal. Thus, m∠1 = m∠2
4(x + 2) = 2x + 24
4x + 8 = 2x + 24
2x = 16
=> x = 16/2
=> x = 8
Now, m∠2 = 2x + 24
m∠2 = 2×8 + 24

we have a dataset of household income, with mean 80,000 and median 50,000 and standard deviation 40,000.we standardize this dataset by calculating the z-scores (the standard scores). a datapoint is mapped to number 2.5 in the standardized dataset. how much was the income of this household?
The income of the household having mean 80,000 and standard deviation 40,000 is 1,80,000
The mean of the Household income = 80,000
The median of the Household income = 50,000
Standard deviation of the household income = 40,000
Z- score of these household income = 2.5
Thus , the income of the household can be calculated by using the normal distribution formula
Z = (X - μ) /σ
where X is the income of the household
μ is the mean of the household income
σ is the standard deviation of the household income.
So, we can re-write this equation as
X = Zσ + μ
Now, let us substitute the known values in the above equation , we get
X = 2.5(40,000) + 80,000
X = 1,00,000 + 80,000
X = 1,80,000
Therefore, the income of the household is 1,80,000 .
