Option D is the correct answer. if the residuals from a fitted regression violate the assumption of homoscedasticity their variance is not constant.
Homoscedasticity: It is an assumption of equal or similar variances in different groups are being compared. It is a condition in which the variance of the residual, or error term, in a regression model, is constant.
This is one of the most important assumptions of parametric statistical tests because they are sensitive to any dissimilarities. It is valid when X and Y are independent.
To deal with this First, we have attempted to transform your target using square root, log, reciprocal square root, or reciprocal transformations.

What value of x is in the solution set of the inequality 9(2x 1) < 9x – 18? –4 –3 –2 –1
The value of x in the solution set of the inequality is -4.
What are inequalities?Inequalities are of two types, > and <. The > sign means that left hand side is greater than the right hand side, while the < sign means that the left hand side is less than than the right hand side.
How to solve inequalities?We can solve the inequality by assuming the inequality sign as the = sign, except that when we divide or multiply one side by (-1), the inequality sign will reverse (for eg it will change from > to <).
9(2x+1) < 9x - 18
2x+1 < x - 2
2x < x - 3
x < -3
This means that x can be any value less than -3 (but not equal to -3 since the sign is < and not ≤) . Hence, the answer is -4.

What is the actual length of the wings of thethe airplane from tip to tip?
Answer:
68cm
Step-by-step explanation:
Because the scale factor is 2, which means the drawing is 2 times smaller than the actual airplane, multiply 34, the length of the wings tip to tip in the drawing by 2.
34 x 2 = 68
Answer: 68 meters
(Hope I'm correct, but read the explanation to make sure)
Step-by-step explanation:
Let's start with what we know. We know that the scale factor is 2, so in our model, from tip to tip, it is 34 cm. However, since the scale factor is 2:
34 * 2 = 68 meters
The area of a rectangle i 42 quare millimeter. The length i 7 millimeter. What i the perimeter of the rectangle?
millimeter
The area of a rectangle is 42 quare millimeter. The length is 7 millimeter. 28 millimeters is the perimeter of the rectangle.
Perimeter = 2 × (Length + Width)
Perimeter = 2 × (7 + 6)
Perimeter = 28 millimeters
To calculate the perimeter of a rectangle, we need to multiply the length and the width of the rectangle, and then multiply that value by 2. In this case, the length is 7 millimeters, and the area is 42 square millimeters. To calculate the width, we can divide the area by the length, which is 42 divided by 7, which is equal to 6. So the width is 6 millimeters. Now we can calculate the perimeter using the formula: Perimeter = 2 × (Length + Width). Plugging in the values, we get: Perimeter = 2 × (7 + 6) = 28 millimeters.

Amy, Becky and Chloe went shopping.
Becky spent only 15% of what Chloe spent.
However, Amy spent 60% more than Chloe.
Together they spent £55.
How much did Amy spend?
Let's say Chloe spent X
Then Amy spent 60% more so Amy spent
X+60% of X =X + 0.6X =1.6X
Becky spent 15% of what Chloe spent so amount spent by Becky =15% of X = .15X
Now, in total, they spent 0.15X+ X + 1.6X =2.75X which is given as £55
So , X=55/2.75 = 20

Find the value of z such that 0.12 of the area lies to the right of z. Round your answer to two decimal places.
Answer:
Step-by-step explanation:
To find the value of z such that 0.12 of the area lies to the right of z, we need to know the distribution of the data and the total area under the curve. If the data follows a normal distribution, the area under the curve is always 1, and 0.12 of the area corresponds to a z-value of approximately 0.84.
We can use a standard normal table or a calculator to find the exact value of z. For example, using a standard normal table, we can find that the z-value corresponding to an area of 0.12 to the right of z is 0.8416.
Therefore, the value of z such that 0.12 of the area lies to the right of z is approximately 0.84.

What is a slope ?
A line's slope is how steeply it slopes from LEFT to RIGHT. The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change. No matter which two locations on the line you choose, the slope of a line is always constant (it never varies).
The ratio of the increase in elevation between two points to the run in elevation between those same two points is referred to as the slope.
The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope. And b is the value of b at the y-intercept (0, b).

The sum of two number is 92. Their difference i 20Let x and y represent the 2 number. Let x=the lager value and smaller valuex = 92 + 20 = 11,y = 92 - 20 = 72
Let x = the larger value and y = the smaller value.
We know that the sum of x and y is 92, so
x + y = 92
We also know that the difference between x and y is 20, so
x - y = 20
Add the two equations to get
2x = 112
Divide by 2 to get
x = 112
Substitute x = 112 into the first equation to get

$
per gallon
Answer: $0.08
Step-by-step explanation:
First, let's find last week's price
Take 35.40 divided by 12 = $2.95 per gallon

A preschool has 100 feet of fencing to enclose 3 sides of a rectangular playground. The fourth side is formed by a wall of the school. The function A(x) = 100x − 2x2 represents the possible area of the playground with side length x feet. Which range is appropriate for this situation?
Answer:
This answer assumes that the function is A(x) = 100x − 2x^2. The function as written is A(x) = 100x - (4 or 4x)
The domain is 0 - 50 feet.
Step-by-step explanation:
The area function is a polynomial with a vertex (hghest area possible) at (25,1250). This is telling us that for a side length of 25 feet, the area is at a maximum of 1250 ft^2. This is actually not totally correct. We only need 3 sides of fencing since the school wall will make up the fourth. The given equation does not seem to allow for this caveat, since it uses 100 feet for all four sides.
Given the equation, the domain for the function A(x) is positive for all values between 0 and 50 feet. The domain is 0 - 50 feet.

The interest amount that will be capitalized is $4.04 million.
What is the interest amount that will be capitalized?The entire cost to purchase a good or service is referred to as an expense. A $30 million piece of equipment with a six-year useful life, for instance, is considered a capital expenditure. An expense is something that calls for the transfer of funds, or fortune in general, from one person or group to another as payment for a good, service, or other type of cost. Rent is a cost to a tenant. Tuition is a cost to parents or students.
The following can be deduced from the information:
Average Expenditure for 2023
= 78 million* 6/6 month + 46 million ** 3/6 month
= 101 million
Amount of interest that should capitalized in 2023 using a specific interest method

Examine the sequence. From viewing the first 2 terms, we know that it can either be a geometric sequence that multiplies by 11/3 every time the term increases or an arithmetic sequence that adds 8 every time the term increases.
Looking at the 2nd and 3rd term, we know it is an arithmetic sequence because 19 is not equal to 11 times 11/3.
A tree, which i approximately 80% of it full height, i preently 60 feet tall. How tall will the tree be when it i fully grown?
The tree will be 75 feet tall when it will be fully grown.
The total tree height is the distance between the tree's base and its highest point on the ground. A yardstick provides a quick and relatively accurate way to gauge the height of a tree.
If the tree is currently 60 feet tall and is approximately 80% of its full height, we can assume that the tree will be 100% of its full height when it is fully grown. To determine the full height of the tree, we can use the proportion:
60 feet / 80% = X feet / 100%
We can then cross-multiply to solve for X:
X = (60 feet * 100%) / 80%
= 75 feet
So, when the tree is fully grown, it will be approximately 75 feet tall.

50% = 0.5
Take 12000 times 0.5 = 6000 students
6000 students would actually enroll
someone help me i hate log functions
Answer:
Step-by-step explanation:
[tex]log_{10}(2000xy)-(log_{10}x})(log_{10}y)=4\\\\log_{10}(2000(xy))-log_{10}(xy)=4\\\\log_{10}(2000)+log_{10}(xy)-log_{10}(xy)=4\\\\log_{10}(2(1000)=4\\\\log_{10}2+log_{10}(1000)=4\\\\log_{10}2+log_{10}(10^3)=4\\\\log_{10}2+3log_{10}(10)=4\\\\log_{10}2\approx0.3\\\\Hence,\\\\log_{10}2+3\neq 4[/tex]
[tex]log_{10}(2yz)-(log_{10}y)(log_{10}z)=1\\\\log_{10}(2(yz))-log_{10}(yz)=1\\\\log_{10}2+log_{10}(yz)-log_{10}(yz)=1\\\\log_{10}2\neq 1[/tex]
[tex]log_{10}(zx)-(log_{10}z)(log_{10}x)=0\\\\log_{10}(zx)-log_{10}(zx)=0\\\\0\equiv0[/tex]

In the first circle, the measure of angle ABC is 24°
In the second circle, the measure of angle ABC is 20°
Circle Geometry: Calculating the measure of anglesFrom the question, we are to determine the measure of angle ABC
In the first diagram,
The measure of the arc is 48°
From one of the circle theorems, we have that
The angle subtended by an arc in a circle is twice the angle subtended at the circumference.
Then, we can write that
2 × ∠ ABC = 48°
∠ ABC = 48°/2
∠ ABC = 24°
Question 5
Using the same theorem,
The angle subtended by an arc at the center of the circle is twice the angle subtended at the circle
∠ ABC = 1/2 × 40°
∠ ABC = 20°
Hence, the measure of the angle is 20°

a) The equation is y = 4/x².
b) The value of x is 2/9 when y = 25.
What is relationship?
The relation in mathematics is the connection between two or more sets of values. Assume that there are two sets of ordered pairs, x and y. If set x and set y are related, then the values of set x are referred to as the domain while the values of set y are referred to as the range.
Given table is
x 1 2 3 4
y 4 1 4/9 1/4.
Given that y is inversely proportional to the square of x.
y∝ 1/x²
y = k/x² where k is proportional constant.
Putting x = 1 and y = 4 in equation y = k/x²:
4 = k/1²
k = 4
Putting x = 2 and y = 1 in equation y = k/x²:
1 = k/2²
k = 4
Putting k = 4 in y = k/x²:
y = 4/x²
Putting y = 25 in y = 4/x²
25 = 4/x²
25x² = 4
Divide both sides by 25:
x² = 4/25
Take square root on both sides:
x = 2/5
