The altitude of the airplane after it descends is 13,409 feet.
What is altitude?The meaning of ALTITUDE is the vertical elevation of an object above a surface (such as sea level or land) of a planet or natural satellite.
Now it is given that,
Initial Altitude of airplane = 14,382 feet
Then plane ascends = 9,372 feet
So, Altitude of airplane = 14,382 feet + 9,372 feet = 23,754 feet
Again airplane descends = 10,345 feet
So, Altitude of airplane = 23,754 feet - 10,345 feet
⇒ Altitude of airplane = 13,409 feet
Thus, the altitude of the airplane after it descends is 13,409 feet.

Given m
11
n, find the value of x and y.
m
(5x+9)
(y+20)
n
(4x+17)
Answer: x=8 and y=29
Step-by-step explanation:
Since the lines M and N are parallel to each other, the corners that are across from each other are equal. This is true for the corners formed by the lines on the top and bottom.
So, all of the given equations can be set equal to each other. ie: (5x+9)=(4x+17)=(y+20).
Now, since the first two expressions both have x as their only variable, set those equal to each other and do not include the y expression.
ie: (5x+9)=(4x+17)
Now solve for x by subtracting 4x from each side.
ie: x+9=17
Now subtract 9 from each side
ie: x=8
Now you have your X value
Use your X value to solve one of the x variable equations.
ie: 5(8)+9
This equals 49.
Use this answer to substitute it in the equation where we set them all equal.
ie: 49=y+20
Now solve for y using this equation
ie: y=29

II. The standard deviation of this new distribution is 5+ 7.
III. The variance of this new distribution is 52 + 72
A) I only
B) II only
C) I and II only
D) I and III only
E) I, II, and III
Answer:
I and III only. Got it correct on Stats test.
Thus, the mean of this new distribution is 168 + 117 and the standard deviation of this new distribution is 5+7. Therefore, option C is the correct answer.
Given that, at King Kong High School, the average weight of senior boys is 168 lbs.
What is standard deviation?Standard deviation is the positive square root of the variance. Standard deviation is one of the basic methods of statistical analysis. Standard deviation is commonly abbreviated as SD and denoted by 'σ’ and it tells about the value that how much it has deviated from the mean value.
Here, a new distribution is created by adding the boys' weights and the girls' weights together.
So, the new average weight of senior boys and girls
= 168+117
= 285 lbs
The new standard deviation is 5+7
= 12 lbs
Thus, the mean of this new distribution is 168 + 117 and the standard deviation of this new distribution is 5+7. Therefore, option C is the correct answer.

Laura's yard is in the shape of a square and a half-circle. She just got a puppy named Sprinkles for her birthday. In order to keep him safe, she wants to line the perimeter of her yard with a fence. How much fencing will she need to enclose the entire yard and keep Sprinkles from running away?
Answer:
The total perimeter she would need to fence would be:
4L + πr
Step-by-step explanation:
Since her yard is a square and half a circle, and she wants to fence the whole distance around the square and the half circle, then she needs to know the perimeter of a square and semicircle.
The perimeter of a square which is the distance around the square is given by 4L where L is the side length.
The perimeter of a circle, which is the circumference of a circle is 2πr, where r is the radius of the circle Therefore, half a circle would be 2πr/2 = πr.
The total perimeter she would need to fence would be:
4L + πr.
A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 95,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 4% each year. How many total fish did the company catch over the first 10 years, to the nearest whole number?
Answer/step-by-step explanation:
We know that during their first year, the company caught 95,000 fish, and the amount of fish caught decreased 4% each year. First, let's calculate 4% of 95,000, by doing the equation: 95,000 x 0.04 = 3,800
So, each year, the company catches 3,800 less fish.
In order to find out how many fish the company caught in ten years, we need to multiply 3,800 x 10 and then subtract it from 95,000. Then we need to multiply that number by 10.
3,800 x 10 = 38,000
95,000 - 38,000 = 57,000 x 10 = 570,000.
Therefore, the company caught a total of 57,000 fish in the first ten years.

Answer:
The equation of the line:
[tex]y=\frac{3}{2}x+9[/tex]
Step-by-step explanation:
Given
The point (-4, 3)m = -2/3We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -2/3
perpendicular to m = -1/m
[tex]=-\frac{1}{\left(\frac{-2}{3}\right)}=\frac{3}{2}[/tex]
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 3/2 and the point (-4, 3)
[tex]y-3=\frac{3}{2}\left(x-\left(-4\right)\right)[/tex]
[tex]y-3=\frac{3}{2}\left(x+4\right)[/tex]
Add 3 to both sides
[tex]y-3+3=\frac{3}{2}\left(x+4\right)+3[/tex]
[tex]y=\frac{3}{2}x+9[/tex]
Thus, the equation of the line:

Find the value of the variable p and YZ if Y is between X and Z, XY=3p, YZ=2p-1, and XZ=6p-6
Using the segment addition postulate, the value of p = 5, and YZ = 9 units.
How to Apply the Segment Addition Postulate?Since point Y lies between points X and Z, the three points are collinear, therefore, based on the segment addition postulate, XY + YZ = XZ.
Given the following:
XY = 3p
YZ = 2p - 1
XZ = 6p - 6
Substitute
3p + 2p - 1 = 6p - 6
Add like terms
5p - 1 = 6p - 6
5p - 6p = 1 - 6
-p = -5
p = 5
YZ = 2p - 1
Plug in the value of x
YZ = 2(5) - 1
YZ = 9 units.

=======================================================
Explanation:
Recall that midsegments are half as long as the side they are parallel to. In this case, midsegment PQ is parallel to segment GJ. This means PQ is half as long as GJ. Phrased another way, we can say GJ is twice as long as PQ.
So,
GJ = 2*PQ
Also, we can see that GR = RJ due to the triple tickmarks they share. This leads to GJ = GR+RJ = RJ+RJ = 2*RJ
Or in short,
GJ = 2*RJ
---------
In summary we can see that
GJ = 2RJGJ = 2PQequating both right hand sides leads to
2RJ = 2PQ
RJ = PQ
Because PQ is 10 units, this means RJ is also 10 units.
--------------------
Another way to see why PQ = RJ is to notice how triangles HPQ and QRJ are congruent triangles (use SAS to prove this). The corresponding pieces PQ and RJ are the same length, so PQ = RJ = 10.

Protozoa are single-celled organisms.
Paramecium aurelia is one type of protozoan. The
number of Paramecium aurelia protozoa doubles
every 1.25 days. There was one protozoan on a slide
5 days ago. How many protozoa are on the slide now?
The number of protozoa makes a series where every next term is double its previous term so on the slide now the number of protozoa is 16.
What is a series?A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.
Number of protozoa 5 days ago = 1
Since protozoa double every 1.25 days.
Number of times protozoa doubles in 5 days ⇒
5 / 1.25 = 4 times.
So,
1 →2 → 4 → 8 → 16
Hence "The number of protozoa on the slide now is 16".

2x + -10 = 10 + -3x
Explanation
Reorder the terms:
-10 + 2x = 10 + -3x
-10 + 2x = 10 + -3x
Solving for variable x
Move all terms containing x to the left, all other terms to the right
Add 3x to each side of the equation
-10 + 2x + 3x = 10 + -3x + 3x
Combine like terms: 2x + 3x = 5x
-10 + 5x = 10 + -3x + 3x
Combine like terms: -3x + 3x = 0
-10 + 5x = 10 + 0
-10 + 5x = 10
Add '10' to each side of the equation.
-10 + 10 + 5x = 10 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 10 + 10
5x = 10 + 10
Combine like terms: 10 + 10 = 20
5x = 20
Divide each side by '5'.
x = 4

The required value of f(-2.2) is 1 for the given function f(x)=x+3. The correct answer is an option (C).
The given function is f(x)=x+3.
To find f(-2.2) on the given graph of f(x) = x + 3, we need to locate the corresponding point on the step graph.
From the information provided, we know that the left-most segment starts at (-5, -1) and ends at (-4, -1), and each segment is 1 unit higher and 1 unit farther to the right than the previous segment.
To determine the value of f (-2.2), we need to find the segment that includes the x-coordinate of -2.2.
Since the x-coordinate -2.2 falls between -4 and -3 (1 unit to the right of the left-most segment), the corresponding y-coordinate is 2 units higher than the starting y-coordinate of -1.
So, f(-2.2) = −1 + 2
f(-2.2) = 1.
Thus, the required value of f(-2.2) is 1.
