Answer:
A: 171.75
B: 170
Step-by-step explanation:
The mean (or average) can be found by...
- add all the numbers together (we will call this y)
- divide the total sum (or y) by the total amount of numbers used to add
Formula:
(x₁ + x₂ + x₃ + ... + xₙ) ÷ n
For A:
(172 + 130 + 173 + 212) ÷ 4 = 171.75
For B:
(136 + 184 + 168 + 192) ÷ 4 = 170

A department store is hiring for the positions of manager, associate manager, and assistant manager. If 15 people have applied for all the positions and are equally qualified for each position, in how many ways can the positions be filled?
Answer:
The positions can be filled in 2730 ways
Step-by-step explanation:
The number of all posible ways is equal to the number of possibilities of who can become the manager, times the number of possibilities of who can become the associate manager, times the number of possibilities of who can become the assistant manager.
Now...
The number of possibilities of who can become the associate manager = 15
The number of possibilities of who can become the associate manager = 14
(it decrease by one because one person already got the position of manager)
The number of possibilities of who can become the assistant manager = 13
(based on the same logic as for the number of who can become the associate manager)
So now we know the number of ways equals...
15 x 14 x 13 = 2730
help please i am stuck
Answer:
x = 25
Angle B = 65 degrees
Angle C = 50 degrees
Step-by-step explanation:
All triangles will add up to 180 degrees.
65 + 3x - 10 + 2x = 180
Combine like terms
55 + 5x = 180
Subtract both sides by 55
5x = 125
Divide both sides by 5
x = 25
Plug in the value for x in angle B:
3(25) - 10
75 - 10
65
Do the same for angle C:
2(25)
50
Check your work:
65 + 65 + 50 = 180
180 = 180
Correct

The two-sided limit exists as long as the limits from either side also exist and are equal. So to compute the limit, you have to compute the one-sided limits,
[tex]\displaystyle\lim_{x\to0^-}f(x)[/tex]
[tex]\displaystyle\lim_{x\to0^+}f(x)[/tex]
f(x) has a different definition and thus different behavior as x approaches 0 depending on which direction x is approaching 0:
• When x approaches 0 from the left (or from below), you use the definition of f for x < 0, so
[tex]\displaystyle\lim_{x\to0^-}f(x) = \lim_{x\to0}(-x-2) = -2[/tex]
• When x approaches 0 from the right (or above), you use the other definition, so
[tex]\displaystyle\lim_{x\to0^+}f(x) = \lim_{x\to0} \left(\frac x2-2\right) = -2[/tex]
The limits from either side match, so the two-sided limit exists and is also -2.
Which is equivalent to 12 - 5x?
-12x+5
-5x+12
5x-12
12x -5
The equivalent expression to 12 - 5x is -5x+12. The correct option is B.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 12 - 5x. The equivalent expression will be calculated as,
-5x+12 = 12 - 5x
Hence, the correct option for the given expression will be B.

Two decimals numbers, to the thousandths, that have a sum of about 5 and a difference of about 3. Then do the math to prove it works.
Answer:
The numbers are approximately: 4.000 and 1.000
Step-by-step explanation:
The given parameters can be expressed as:
[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]
[tex]\frac{x}{1000} - \frac{y}{1000} \approx 3[/tex]
Required
Determine the numbers
In each of the equations, multiply by 1000
[tex]1000 * [\frac{x}{1000} + \frac{y}{1000} \approx 5][/tex]
[tex]x + y \approx 5000[/tex]
[tex]1000 * [\frac{x}{1000} - \frac{y}{1000} \approx 3][/tex]
[tex]x-y \approx 3000[/tex]
So, we have:
[tex]x + y \approx 5000[/tex]
[tex]x-y \approx 3000[/tex]
Add the two equations
[tex]x + x + y - y \approx 5000 + 3000[/tex]
[tex]2x \approx 8000[/tex]
Solve for x
[tex]x \approx 8000/2[/tex]
[tex]x \approx 4000[/tex]
Substitute [tex]x \approx 4000[/tex] in [tex]x + y \approx 5000[/tex]
[tex]4000 + y \approx 5000[/tex]
[tex]y \approx 5000 - 4000[/tex]
[tex]y \approx 1000[/tex]
Using:
[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]
We have:
[tex]\frac{4000}{1000} + \frac{1000}{1000} \approx 5[/tex]
[tex]4.000 + 1.000 \approx5[/tex]
This implies that, the numbers approximates to 4.000 and 1.000, respectively.

Law of sines:
sin(C)
C
Answer:
Step-by-step explanation:
''he Law of Sines is the relationship between the sides and angles of non-right (oblique) triangles . Simply, it states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle.''
The best approximation value of a by using sine rule is 3.0cm. so option C is correct.
What is sine rule?The sides and angles of non-right triangles are related according to the Law of Sines.
The relationship between the angles and lengths of the sides:
a/sinA = b/sinB = c/sinC
We know according to law of sines:
a/sinA = b/sinB = c/sinC
by putting the values we can write,
a/sin40° = 4.7/sin95°
a = (4.7 ×sin40°)/sin95°
= 3.032
by putting the value of Sin40° and Sin95°.
we get a = 3.03cm.
Approximation value of a is 3.0cm.

According to the US Census, the percent of residents aged 65 or older in the 50 states and District of Columbia has mean 13.26% and standard deviation of 1.67% Find and interpret the standardized score for the state of Colorado, which had 9.7% of residents age 65 or older.
Answer:
z = -2.13
The standardized score for the state of Colorado is negative and this means the score is smaller than the mean.
Step-by-step explanation:
The above question can be solved using z score.
The formula for z score is given as:
z = (x-μ)/σ,
where
x is the raw score = 9.7%
μ is the population mean = 13.26%
σ is the population standard deviation = 1.67%
z = z score or standardize score
Hence,
z = 9.7 - 13.26/1.67
z = -2.13174
Approximately z = -2.13
Therefore, the standardized z score for the state of Colorado is negative and this indicates that the score is below or smaller than the mean.

Answer:
The answer is D
Step-by-step explanation:
the standard equation for circle is (x －h)² ＋(y －k)² = r² which h is the x coordinate, k is the y coordinate, r is radius. In this case, both x coordinate and y coordinate are 0, so the left side of the equation is x² + y², since the radius is √249, the r² is 249. So the equation is x² + y² = 249, and the answer is D.
