Answers
Answer:
Step-by-step explanation:
Hello!
Given the variables
Y: Cost of a previously owned Camry.
X: Mileage of a previously owned Camry.
Scatter plot in attachment.
As you can see in the scatter plot, the price of the previously owned Camry decreases as their mileage increases this suggest that there is a negative linear regression between these two variables.
Hypothesis test for the y-intercept
H₀: β₀ = 0
H₁: β₀ ≠ 0
Level of significance α: 0.01
p-value < 0.0001
The decision is to reject the null hypothesis. You can conclude that the population mean of the cost of a previously owned Camry, when the mileage is zero, is different from zero.
H₀: β = 0
H₁: β ≠ 0
Level of significance α: 0.01
p-value: 0.0003
The decision is to reject the null hypothesis. You can conclude that the population mean of the cost of a previously owned Camry is modified when the mileage increases in one unit.

Find the value of each variable in the parallelogram. Round your answers to the nearest tenth, if necessary. G a = (46) K (3a +19) b H 56°
Answers
The value of every variable in the parallelogram is: a = 9 HK = 27.0 GK = 46 G = 63.5°
What do you mean by Parallelogram ?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.These shapes include squares, rectangles, rhombuses, and rhomboids. All of these shapes have four sides, four corners, and four angles
We know that sides of a parallelogram are parallel and congruent, as opposite angle
According to question that GA equals HK, as:
46 is equal to 3a plus 19 When we subtract 19 from both sides, we get:
27 x 3a is the result of dividing both sides by 3:
we know that opposite angles in a parallelogram are congruent, we can use a = 9. Since angle H is 56 degrees, angle K must also be 56 degrees. The length of side HK can be determined using the Law of Cosines:
HK2 = GA2 + GK2 - 2(GA)(GK)cos(H) When we substitute the values we are familiar with, we obtain:
After solving the equation we obtain: HK2 = 462 + (3a + 19)2 - 2(46)(3a + 19)cos(56°).
HK2 = 2112 + 9a2 + 342a - 2764cos(56°) HK2 = 2112 + 9(9)2 + 342(9) - 2764cos(56°) HK2 732.4 By taking the square root of both sides, we obtain the following results:
∵ GA = 46, we can use the parallelogram's opposite sides being congruent to determine the length of side GK: HK 27.0
Then, we can use the Law of Cosines to determine the angle G's measurement:
cos(G) = (HK2 + GA2 - GK2) / (2(HK)(GA)) Using the values we are familiar with, we get,
cos(G) = (27.02 + 462 - 462) / (2(27.0)(46)) cos(G) 0.465 Using the inverse cosine, we get the following:
G ≈ 63.5°
Hence, the worth of every variable in the parallelogram is:
a = 9 HK = 27.0 GK = 46 G = 63.5°

a rectangular doorway has a temporary support beam across its diagonal. the height of the doorway is 2 times its width. if the beam across the diagonal is 14 feet, how wide is the door?
Answers
Answer:
The door has a width of 6.26 feet, with a height of 12.52 feet.
Step-by-step explanation:
You can solve this by taking two pieces of information we're given:
1) the diagonal size of the doorway is 14 feet
2) the height of the doorway twice its width
First lets describe the width and height using the diagonal length. We can do that with the Pythagorean theorem:
w² + h² = 14²
Now we can use the relationship between the width and height to eliminate one variable:
w² + (2w)² = 14²
w² + 4w² = 14²
5w² = 196
w² = 39.2
w ≈ 6.26
So the door has a width of 6.26 feet, with a height of double that, 12.52 feet.
Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The width of the door is 6.26 ft or √(196/5)ft.
What is Pythagoras theorem?The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between the three sides of a right triangle in Euclidean geometry. The size of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides, according to this rule.
Given the length of the rectangular door is two times its width, therefore, the length and width of the rectangular door are,
Width = x
Length = 2x
Since the measure of the diagonal of the rectangular door is 14 feet, therefore, using the Pythagorus theorem we can write,
x² + (2x)² = 14²
x² + 4x² = 196
5x² = 196
x² = 196/5
x = 6.26099 ≈ 6.26ft
Hence, the width of the door is 6.26 ft or √(196/5)ft.

They can buy 120 vans, 60 small trucks, and 80 large trucks.
How to find the number of van, small trucks and large truck needed?The truck company plans to spend 10 million on 260 vehicles. Each commercial van cost 25,000 dollars. Each small truck 50,000 dollars and each large truck 50,000 dollars. They needed twice as many van as small truck
Therefore,
let
s = number of small truck
number of van = v
let
l = number of large truck
v + s + l = 260
25,000(v) + 50,000(s) + 50,000(l) = 10,000, 000
v + 2s + 2l = 400
Hence,
v = 2s
So,
2s + 2s + 2l = 400
4s + 2l = 400
2s + s + l = 260
3s + l = 260
2s + l = 200
s = 60
l = 200 - 2(60)
l = 200 - 120
l = 80
v = 2(600 = 120
Therefore, they can buy the following:
number of small truck = 60
number of van = 120
number of large truck = 80

What are the coordinates of the vertices of the image of a rectangle?
In this question we find the coordinates of the four vertices of the rectangle, whose locations are described in the statement. Each point must be transformed by the following sequence of rigid transformations:
Reflection over the x-axis: P'(x, y) = P(x, y) + (0, - 2 · p)Reflection over the y-axis: P''(x, y) = P'(x, y) + (- 2 · p', 0)If we know that P(x, y) = (1, 4), Q(x, y) = (6, 4), R(x, y) = (6, 1) and S(x, y) = (1, 1), then the locations of the images of the four vertices are:
P'(x, y) = (1, 4) + (0, - 8)
P'(x, y) = (1, - 4)
P''(x, y) = (1, - 4) + (- 2, 0)
P''(x, y) = (- 1, - 4)
Q'(x, y) = (6, 4) + (0, - 8)
Q'(x, y) = (6, - 4)
Q''(x, y) = (6, - 4) + (- 12, 0)
Q''(x, y) = (- 6, - 4)
R'(x, y) = (6, 1) + (0, - 2)

Point :
Parallel lines have same slopes.
_________________________________
\(6x + 5y = 11\)
Subtract sides -6x
\( - 6x + 6x + 5y = - 6x + 11\)
\(5y = - 6x + 11\)
Divided sides by 5
\( \frac{5}{5}y = \frac{ - 6}{5}x + \frac{11}{5} \\ \)
\(y = - \frac{6}{5}x + \frac{11}{5} \\ \)
Look :
This is the slope-intercept of the given line. We know that the coefficient of x is the slope of the linear functions in slope-intercept form.
Thus the slope of the line which we want is :
\(slope = - \frac{6}{5} \\ \)
_________________________________
We have following equation to find the point-slope form of the linear functions.
\(y - y(given \: point) = (slope) \times (x - x(g \: p) \: ) \\ \)
Now just need to put the slope and the coordinates in the above equation.
\(y - ( - 8) = - \frac{6}{5} \times (x - ( - 2) \: ) \\ \)
\(y + 8 = - \frac{6}{5}(x + 2) \\ \)
To find the slope-intercept form of the above equation we need to take the y alone and then simplifies the equation.
Look :
\(y + 8 = - \frac{6}{5}x - \frac{12}{5} \\ \)
Subtract sides by -8
\(y + 8 - 8 = - \frac{6}{5}x - \frac{12}{5} - 8 \\ \)
\(y = - \frac{6}{5}x - \frac{12}{5} - \frac{40}{5} \\ \)
\(y = - \frac{6}{5}x - \frac{52}{5} \\ \)
This is what we want...
_________________________________
Now we must Check the equation by using the given point :
\(( - 8) = - \frac{6}{5}( - 2) - \frac{52}{5} \\ \)
\( - 8 = \frac{12}{5} - \frac{52}{5} \\ \)
\( - 8 = \frac{ - 52 + 12}{5} \\ \)
\( - 8 = \frac{ - 40}{5} \\ \)
\( - 8 = - 8\)
So the equation is right.

Answer:
|x| > 6
Step-by-step explanation:
The correct statement is: |x| > 6.
This means that the distance between x and 0 on the number line is greater than 6 units, so x can be any number greater than 6 or less than -6.
The options given are:
|x| < 6: This statement indicates that the distance of x from 0 on the number line is less than 6 units. In other words, x could be any value between -6 and 6, not including -6 and 6.|x| > 6: This statement indicates that the distance of x from 0 on the number line is greater than 6 units. Therefore, x could be any value less than -6 or greater than 6.|x| = 6: This statement indicates that the distance of x from 0 on the number line is exactly 6 units. Therefore, x could be either 6 or -6.|x| ≥ 6: This statement indicates that the distance of x from 0 on the number line is greater than or equal to 6 units. Therefore, x could be any value less than or equal to -6 or greater than or equal to 6.|x| ≤ 6: This statement indicates that the distance of x from 0 on the number line is less than or equal to 6 units. In other words, x could be any value between -6 and 6, including -6 and 6.Therefore, the correct statement is |x| > 6.
here's how to express the statement |x| > 6 as an inequality part 10a^2
| x | > 6
Squaring both sides of this inequality, we get:x^2 > 6^2
Simplifying, we get:x^2 > 36
Multiplying both sides by 10, we get:10x^2 > 360
So the inequality we get after multiplying both sides by 10 is:10x^2 - 360 > 0
Therefore, the inequality for |x| > 6 in terms of 10a^2 is:10x^2 - 360 > 0
Note that this inequality does not directly involve "a," as it is not mentioned in the original statement.
