For figure ABCDEF shown here, identify the image after a clockwise rotation of 240°, or counterclockwise
rotation of 120°. The naming always begins at the top of the figure and proceeds clockwise. For example,
a reflection across AD has an image of AFEDCB. Drag and drop each letter into the correct box to identify
the image after a clockwise rotation of 240°, or a counterclockwise rotation of 120°.
Answer:
Step-by-step explanation:
Since, ABCDEF is a regular hexagon,
Measure of central angle of a regular polygon = [tex]\frac{360}{n}[/tex]
where n = number of sides of the polygon
Measure of central angle of regular hexagon = [tex]\frac{360}{6}[/tex] = 60°
That means when we rotate a regular hexagon by an angle in the multiple of 60°, hexagon overlaps itself.
Therefore, by the rotation of 240° clockwise, point C will replace the position of point A.
Image of hexagon ABCDEF will become CDEFAB.
Similarly, after rotation by 120° counterclockwise about the center image hexagon will be EDCBAF.

Compute the variance of job satisfaction scores for executives and middle managers (to 2 decimals). Executives Middle managers d. Compute the standard deviation of job satisfaction scores for both probability distributions (to 2 decimals). Executives Middle managers e. What comparison can you make about the job satisfaction of senior executives and middle managers? - Select your answer -
Answer:
Kindly see explanation
Step-by-step explanation:
Given the data:
JOB satisfaction (x) : 1, 2, 3, 4, 5
IS Senior ; p(x) : 0.05, 0.09, 0.03, 0.42, 0.41
IS Middle ; p(x) : 0.04, 0.10, 0.12, 0.46, 0.28
Expected value of job satisfaction for senior executives :
E(x) = Σp(x) * x = [(1*0.05) + (2*0.09) + (3*0.03) + (4*0.42) + (5*0.41)]
= 4.05
B) Σp(x) * x = [(1*0.04) + (2*0.10) + (3*0.12) + (4*0.46) + (5*0.28)]
= 3.84
C.) Job variance for executives:
Σ(x - E(x))² * p(x) :
((1 - 4.05)^2 * 0.05) + ((2 - 4.05)^2 * 0.09) + ((3 - 4.05)^2 * 0.03) + ((4 - 4.05)^2 * 0.42) + ((5 - 4.05)^2 * 0.41)
= 1.2475 = 1.25 ( using calculator)
job variance for middle managers :
Σ(x - E(x))² * p(x) :
((1 - 3.84)^2 * 0.04) + ((2 - 3.84)^2 * 0.10) + ((3 - 3.84)^2 * 0.12) + ((4 - 3.84)^2 * 0.46) + ((5 - 3.84)^2 * 0.28)
= 1.1344 = 1.13 (using calculator)
Standard deviation(sd) for (senior managers) :
sd = √variance
sd = √1.25 = 1.118 = 1.12
Standard deviation(sd) for (middle managers) :
sd = √variance
sd = √1.13 = 1.063 = 1.06
The expected value (mean) for senior executives (4.05) is slightly higher Than obtained for middle managers (3.84). Similarly the measure of Variation in job satisfaction ; standard deviation and variance is also higher for senior managers than in middle managers.

8. Ace Cable TV offers two monthly plans. Plan A costs $55 a month plus $3 for each premium
channel the customer selects. Plan B costs $25 a month plus $8 for each premium channel
the customer selects. What number of channels will cause the cost of both plans to be the
same?
Answer:
8x:16
Step-by-step explanation:
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
55 + 3x = 25 + 8x
Where x is the number of premium channels
The number of channels at which the cost of both plans will be the same is 6.
What is an equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Number of premium channels = x
Plan A:
Monthly cost = $55
Cost of each premium = $3
Total cost = 55 + 3x _____(1)
Plan B:
Monthly cost = $25
Cost of each premium = $8
Total cost = 25 + 8x ______(2)
From (1) and (2).
The number of channels when the cost of both plans will be same.
55 + 3x = 25 + 8x
Subtract 25 on both sides.
55 - 25 + 3x = 8x
30 + 3x = 8x
Subtract 3x on both sides.
30 = 8x - 3x
30 = 5x
Divide both sides by 5.
x = 6
Thus,
The number of channels at which the cost of both plans will be the same is 6.

What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
f(x) =x/2 -2
g(x) = 2x2 + x - 3
Now,
To find (8 + g)(x), we need to add 8 to the function g(x).
g(x) = 2x^2 + x - 3
(8 + g)(x) = 8 + g(x) = 8 + (2x^2 + x - 3)
Simplifying the expression inside the parentheses:
= 2x^2 + x + 5
Therefore, the function (8 + g)(x) will be equal to 2x^2 + 3x/5 - 5.
