Answer: A. 5x+x+18 = 180
Step-by-step explanation:
For B you need to find the value of x first.
5x + x + 18 = 180 is your equation.
Combine like terms: 5x+x = 6x
Equation should now look like this
6x + 18 = 180
Subtract 18 to both sides 180-18 = 162
Do 162/6 = 27
X = 27

A plastics company has 75 employees. Management wants to gather data about working conditions. A random sample of 30 employees was selected to receive an anonymous survey. Of those selected, 22 completed the survey. In this scenario, the population is . In this scenario, the sample is .
Answer:
22 completed surveys
Step-by-step explanation:
In the scenario described above, the sample to be used is the information given by the 22 completed surveys. This is because, the remaining 8 initial samples give no information regarding the working condition of employees. Hence, this data points are the null points and may have to be removed from the data.
Therefore, the sample in the scenario described above are the 22 completed surveys from the initial 20 samples selected.

Answer:
B and D are correct.
Step-by-step explanation:
First, we find the length of ALL the sides using the Pythagorean Theorem.
16² + b² = 20²
256 + b² = 400
b² = 144
[tex]\sqrt{144}[/tex] = 12
Now, we know that sine is opp/hyp, cosine is adj/hyp, and tangent is opp/adj.
A is incorrect because that's supposed to be cos. B is correct because that is indeed cos. C is incorrect. D is correct. E and F are incorrect because it's supposed to be sin.
Don't know if any of that made sense. All you need to do is remember the difference between sine, cosine, and tangent.
Answer:
The answer is B and D.
Step-by-step explanation:
Length of ladder AC = 20 feet
Height of the highest point of the ladder from ground AB = 16 ft
By Pythagoras theorem,
AC² = BC² + AB²
BC² = AC² - AB²
BC = √(20)^2-(16)^2
= √400-256
= √144
= 12
Now, Sinθ = opposite side/hypotenuse = AB/AC
= 16/20
Cosθ = adjacent side/hypotenuse = BC/AC
= 12/20
Therefore, A and D are the correct options.

Show that the area of triangle DEF is 11 cm2.
9514 1404 393
Explanation:
The length CD can be found from the Pythagorean theorem.
CF² + CD² = DF²
2² + CD² = (2√10)²
CD² = 40 -4 = 36
CD = √36 = 6
From here, any of several methods could be used to find the area of ΔDEF.
One of them is to subtract the areas of the triangles that are not ΔDEF from the area of the rectangle ABCD.
area ABCD = bh = (6 cm)(5 cm) = 30 cm²
area ΔADE = 1/2bh = 1/2(4 cm)(5 cm) = 10 cm²
area ΔBEF = 1/2bh = 1/2(2 cm)(3 cm) = 3 cm²
area ΔCDF = 1/2bh = 1/2(6 cm)(2 cm) = 6 cm²
Then the area of interest is ...
area ΔDEF = area ABCD -area ΔADE -area ΔBEF -area ΔCDF
area ΔDEF = (30 -10 -3 -6) cm²
area ΔDEF = 11 cm²
__
Alternate solution
If we define A as the origin of a coordinate system, then the coordinates of the vertices of ΔDEF are ...
D(0, 5), E(4, 0), F(6, 3)
The area can be computed as half the absolute value of the sum of the determinants of 2×2 matrices consisting of adjacent points.
[tex]A=\dfrac{1}{2}\left|\left|\begin{array}{cc}0&5\\4&0\end{array}\right|+\left|\begin{array}{cc}4&0\\6&3\end{array}\right|+\left|\begin{array}{cc}6&3\\0&5\end{array}\right| \right|\\\\=\dfrac{1}{2}|(0-20)+(12-0)+(30-0)|=\dfrac{1}{2}(22) = \boxed{11}[/tex]

Additional comment
The solution using coordinates is effectively equivalent to the computation of the area of trapezoid ABFD, less the areas of triangles EBF and AED.

For the data set 62, 73, 74, 75, 76, the mean is 72. What is the mean absolute deviation?
A. The mean absolute deviation is 4
B. The mean absolute deviation is 20
C. The mean absolute deviation is 5
D. The mean absolute deviation is 72
plz help i need to know asap
Answer: A. The mean absolute deviation is 4
Step-by-step explanation:
Mean absolute deviation (MAD) is found by finding the absolute value of difference between each number in set and mean, adding them together, then dividing by total numbers in set.
Differences
72-62= 10
72-73= 1
72-74= 2
72-75= -3
72-76= -4
add the absolute values...
10+1+2+3+4=20
divide by 5 because that is how many numbers in set...

A shipping container has a volume of 48 cubic meters. What could be the dimensions (length, width, height) of the container if none of the dimensions are 1 m? Explain how you found the dimensions.
Answer:
6m * 4m * 2m
Step-by-step explanation:
Given that :
Cubic volume = 48 m³
Possible dimension if none of the dimensions is 1 m
Volumetric Dimension = (length * width * height)
The product of the three dimensions must give 48m³
Constraint : none of the dimensions has a volume of 1 m.
Hence, possible dimension :
6m * 4m * 2m = 48m²
Hence, one possible dimension is :
6m * 4m * 2m
In pqr the measure of r is 90 degrees the measure of q is 38 degrees and qr is 8.8 feet. Find the length of pq to the nearest tenth of a foot
Answer:
11.2 feets
Step-by-step explanation:
Angle, P = 180 - (38 + 90) = 52
Using trigonometry :
Length pq:
SinP = opposite / hypotenus
Sin52 = 8.8 / pq
0.7880107 * pq = 8.8
pq = 8.8 / 0.7880107
pq = 11.167361
Hence, length of pq = 11.2 feets
list all prime numbers between 27 and 35.
Answer:
29 and 31 are the only primes.
The prime numbers that are between 27 and 35 are 29 and 31.
Prime numbers
Prime numbers are those values that can only be divided by 1 and itself (so the result is an integer).
Thus, analyzing all integer values between 27 and 35 we have: 28,29,30,31,32,33,34.
Among these values, the only ones that are not divisible by numbers other than 1 and themselves are 29 and 31.

What ismediaUntitled111538744764.
Answer:
A. 60°
Step-by-step explanation:
∠BEC = 1/2 arc BC = 32°
∠CED = ∠BED - ∠BEC = 62° - 32° = 30°
arc CD = 2 x ∠CED = 2 x 30° = 60°
The measure of the arc CD of the circle is 60°
Given data:
The central angle is an angle with two arms and a vertex in the middle of a circle.
The central angle of a circle formula is as follows.
Central Angle = ( s x 360° ) / 2πr
And, Central Angle = 2 x Angle in other segment
So,
∠BEC = 1/2 arc BC = 32°
The measure of the angle ∠CED is determined as:
∠CED = ∠BED - ∠BEC = 62° - 32° = 30°
So, the measure of the arc from the central angle is:
arc CD = 2 x ∠CED = 2 x 30° = 60°
Hence , the measure of arc CD = 60°

Focus on the angles at the bottom right
Those two angles add to 180 since they form a straight line. We consider them supplementary angles.
x+(4x-20) = 180

5x = 180+20
5x = 200
x = 200/5

The equations of two lines are y = -x - 6 and 2x - 3y = -2. What is the value of the y in the solution for this system of linear equations?
Answer:
x = - 4
Step-by-step explanation:
y = -x - 6
2x - 3y = -2
Insert the first equation y = -x-6 into the second 2x - 3y = -2 .
2x - 3 (-x-6) = -2
2x +3x + 18 = -2
5x = -2 - 18
5x = - 20
x = - 20/5
x = - 4
