The final answer based on the given information, the correct answer is D.
Ordinary linear regression predicts the expected value of a given unknown quantity (the response variable, a random variable) as a linear combination of a set of observed values (predictors). This implies that a constant change in a predictor leads to a constant change in the response variable (i.e. a linear-response model). This is appropriate when the response variable has a normal distribution.
The relationship between the data points on the normal probability plot is approximately linear, which suggests that the variable under consideration is not normally distributed. A normal probability plot of a normally distributed variable would show a straight line, but the plot shown in this question appears to have a slight curve. Therefore, the variable is probably not normally distributed.

The wall is to be 5ft by 7 ft. A brick is 4 inches by 12 inches. How many bricks are needed
ok
Dimensions = 5 ft x 7 ft
Brick = 4 in x 12 in
1.- Convert ft to in
1 ft -------------------- 12 in
5 ft ------------------- x
x = (5 x 12) / 1
x = 60 in
1 ft -------------------- 12 in
7 ft -------------------- x
x = (7 x 12) / 1
x = 84 in
2.- Calculate the area of the wall
Area = 60 x 84
= 5040 in^2
3.- Calculate the area of a brick
Area = 4 x 12 = 48 in^2
4.- Divide the area of the wall by the area of the brick
Number of bricks = 5040 / 48
= 105
There will be 105 brick on the wall.

how to determine if a relation is a function calculator
Answer:
A relation is defined as the collection of inputs and outputs which are related to each other in some way. In case, if each input in relation has accurately one output, then the relation is called a function.
Based on the given relation, we found that it is not a function because it has repeating x-values. Remember, for a relation to be a function, each input (x-value) must correspond to exactly one output (y-value).
To determine if a relation is a function, you need to check if each input (x-value) corresponds to exactly one output (y-value). You can use the following steps:
1. Identify the given relation as a set of ordered pairs, where each ordered pair represents an input-output pair.
2. Check if there are any repeating x-values in the relation. If there are no repeating x-values, move to the next step. If there are repeating x-values, the relation is not a function.
3. For each unique x-value, check if there is only one corresponding y-value. If there is exactly one y-value for each x-value, then the relation is a function. If there is more than one y-value for any x-value, then the relation is not a function.
Let's consider an example relation: {(1, 2), (2, 3), (3, 4), (2, 5)}.
Step 1: Identify the relation as a set of ordered pairs: {(1, 2), (2, 3), (3, 4), (2, 5)}.
Step 2: Check for repeating x-values. In our example, we have a repeating x-value of 2. Therefore, the relation is not a function.

Which statement is not true about rational numbers. A.All integers are rational numbers B.Rational numbers include repeating and terminating decimals C. All numbers are rational numbers D.The number of pie is a rational number
Answer:
C. All numbers are rational numbers
Step-by-step explanation:
In mathematics, any number that can be stated in fraction form or ratios is said to be a rational number. This simply means that some numbers cannot be written in fraction form and so all numbers are not rational numbers.
Examples of rational numbers include terminating decimals, integers, repeating decimals and the fractions.
The other non-rational numbers are called irrational numbers, as they cannot be written in fraction form.

Write an equation for the line that is parallel to the given line and that passes through the given point.
y = –5x + 3; (–6, 3)
A. y = –5x – 27
B. y = 5x – 9
C. y = –5x + 9
D. y = –5x + 27
Answer:
A. y = –5x – 27
Step-by-step explanation:
You would need a new y-intercept in order for this to be parallel. So you use the points given and the slope and fill it in. 3=-5(-6)+b. 3=30+b. Then subtract 30 from both sides. -27=b. Then just put it all back into slope intercept form. y=-5x-27.
y = –5x + 3
slope of the given line by comparing with y=mx+b is
m= - 5
Concept is that the slope of parallel lines are equal so we need a line with slope same as m=-5
and passes through point (-6,3)
Equation using the point slope equation
y-3 = -5 (x-(-6))
y-3=-5(x+6)
y-3= -5x-30
y= -5x -27

The launch used for captain lighners scenic tours hold 170 litres of fuel. The boat uses 34L each hour. i need an equation for this please help
Answer:
The information we have is:
The boat can hold 170 L of fuel
The boat uses 34L each hour.
With this information, we can find the total amount of time that the boat can be used.
If the boat is used x hours, then it needs:
x*34L of fuel.
And the maximum amount of fuel that the boat can use uis170 L
Then we can solve:
x*34L = 170L
Now we can divide both sides by 34L to isolate x.
x = 170L/34L = 5
This means that the boat can be used for 5 hours.

(1) The area of the trapezoid is 192 square meters.
(2) The area of the circle is A = 144π square cm or A ≈ 452 square cm.
(3) The circumference of the circle is C = 24π cm or C ≈ 75 cm.
(4) The perimeter of the figure is ≈ 110 cm.
(5) The area of the figure is 321 square meters.
What is the area?The measurement that indicates the size of a region on a plane or curved surface is called the area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
(1)
The height of the trapezoid is 12m and the lengths of the parallel sides are 11m and 21 m.
The area of the trapezoid is:
A = (1/2)(11 + 21)(12)
A = 192 square meters.
(2)
The area of the circle with a radius of 12 cm is:
A = π(12)²
A = 144π
A ≈ 452 square cm.
(3)
The circumference of the circle with a radius of 12 cm is:
C = 2π(12)
C = 24π
C ≈ 75 cm
(4)
To find the perimeter of the figure, first, find the circumference of the semicircle,
The diameter of the semicircle is 30 - 12 = 18.
Therefore, the radius is 18/2 = 9 cm.
Hence, the perimeter of the figure is:
12 + 20 + 30 + 20 + π(9)
≈ 110 cm
(5)
To find the area of the figure, first, find the area of the large horizontal rectangle, then the upper triangular part, and then the lower rectangular part, and add them together.
The area of the large horizontal rectangle is:
(24 + 5) × 8
= 232
The area of the triangular portion is:
(1/2)×(24 + 5 -10 -10)×12
= 54
The area of the small rectangular part is:
5×7
=35
Now, add all the areas together to find the total area of the figure:
232 + 54 + 35
= 321
Hence, the area of the fifth figure is 321 square meters.

order the measurements from greatest to least 45 inches, 6 yards, and 2 and1/4 feet
Answer:
2.25 feet, 45 inches, and 6 yards
Step-by-step explanation:
first, convert all to the same unit of measurement
I will use inches
45 inches = 45 inches
6 yards, 1 yard = 3 feet so 6 yards are equal to 18 feet and 1 foot is equal to 12 inches so 12*18 is 216 inches so 6 yards = 216 inches
Next 1 foot equals 12 inches so 2.25 * 12 = 27 so 2.25 feet = 27 inches.
Now let's look at the complete conversion
45 inches
6 yards = 216 inches
2.25 feet = 27 inches
looking at the inches we can see that 27 is the least then 45 then 216 therefore
2.25 feet < 45 inches < 6 yards so the order is
2.25 feet, 45 inches, and 6 yards

Which graph best represents -2y =4x - 8 ? ASAP like RIGHT NEOW
The equation - 2y = 4x - 8 in slope intercept is y = - 2x + 4.
Consider the function,
- 2y = 4x - 8
The equation of a line in slope intercept form is y = mx + b where m is the slope and b is the y-intercept.
So,
- 2y = 4x - 8
y = - 2x + 4
Now,

y = - 2(0) + 4 = 4
When x = 1,
y = - 2(1) + 4 = 2
When x = 2,
y = - 2(2) + 4 = 0
When x = - 1,
y = - 2( - 1 ) + 4 = 6
When x = - 2,

Determine the equation of the circle with center (-7, 2) containing the point
(-16,8).
The equation of the circle with center (-7, 2) containing the point
(-16,8) is (x + 7)^2 + (y - 2)^2 = 117.
How to determine the equation of the circleThe equation of a circle with center (h, k) and radius r is:
(x - h)^2 + (y - k)^2 = r^2
We are given the center of the circle as (-7, 2) and a point on the circle as (-16, 8).
Using the formula, we can substitute the values into the equation:
(-16 - (-7))^2 + (8 - 2)^2 = r^2
(-16 + 7)^2 + 6^2 = r^2
(-9)^2 + 36 = r^2
81 + 36 = r^2
r^2 = 117
Therefore, the equation of the circle is:
(x - (-7))^2 + (y - 2)^2 = 117
Simplifying:
(x + 7)^2 + (y - 2)^2 = 117
So, the equation of the circle is (x + 7)^2 + (y - 2)^2 = 117.

A ________ is the ratio of probabilities that two genes are linked to the probability that they are not linked, expressed as a log10.
LOD score
A LOD score is the ratio of probabilities that two genes are linked to the probability that they are not linked, expressed as a log10. This measure is commonly used in linkage analysis, a statistical method used to determine whether genes are located on the same chromosome and thus tend to be inherited together.
In linkage analysis, the LOD score is used to determine the likelihood that two genes are linked, based on the observation of familial inheritance patterns. A LOD score of 3 or higher is generally considered to be strong evidence for linkage, indicating that the likelihood of observing the observed inheritance pattern by chance is less than 1 in 1000.
The LOD score is also used to estimate the distance between two linked genes, with higher LOD scores indicating that the two genes are closer together on the chromosome. In general, the LOD score is a useful tool for identifying genetic loci that contribute to complex diseases or traits.
