m-137.25=30.75
What number is m?
Answer: it is 168
Step-by-step explanation: m−137.25=30.75
Step 1: Add 137.25 to both sides.
m−137.25+137.25=30.75+137.25
m=168

What is a relation and what makes it different from a function? How can you determine the domain and range of a function?
Answer:
Note that both relations and functions have domains and ranges. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.
For the function f(x)=−x2+x−7, find f(1)
Answer:
f(1)= -(1)2 + (1) -7
f(1)= -1+1-7
f(1)= -7
Step-by-step explanation:
when you substitute 1 in the function it doesn't carry the negative sign it's independent
What is the volume of this figure? *
10 m
2 m
4 m
length×width×height= volume
Answer:
Given,
l = 10 m
b = 2m
h = 4m
Now,
Volume of a cuboid = l×b×h
= 10 × 2 × 4 m
= 20 × 4
= 80 m

since the standard deviation is 14
variance=the square of the standard deviation i.e
14*14=196

D; The outlier
Answer:
D - outlier
Step-by-step explanation:
It can’t be A - the spread would the minimum and maximum.
‘Can’t be B - the mean in the overall average, which would probably be a bit higher than 13
Can’t be C - the median is the “middle” number when ordered smallest to largest. It would be 13 in this example
24 is an odd number compared to the rest. It seems like it might be an error in the data, because it is so different than all the rest - hence it is the outlier.

Using the Chisquare distribution calculator :
Chisquare :
(Observed - Expected)² ÷ Expected
Chisquare value = 1.759
Degree of freedom (df) = (row - 1) * (column - 1)
Df = (9-1) * (3-1) = 8*2 = 16 at α = 0.10
Pvalue = 0.999
Decision region :
Reject H0 if Pvalue < α
Since, 0.999 > 0.10 ; Then, Fail to reject H0
Hence, there is no difference in the mean price and the store means.

DJ Titus is making a playlist for a radio show; he is trying to decide what 10 songs to play and in what order they should be played. Step 1 of 2 : If he has his choices narrowed down to 7 blues, 7 disco, 5 pop, and 7 reggae songs, and he wants to play no more than 4 reggae songs, how many different playlists are possible
Answer:
Different playlists possible = 18287141644800
Step-by-step explanation:
Given - DJ Titus is making a playlist for a radio show; he is trying to
decide what 10 songs to play and in what order they should be
played.
Step 1 of 2 : If he has his choices narrowed down to 7 blues,
7 disco, 5 pop, and 7 reggae songs.
To find - He wants to play no more than 4 reggae songs.
How many different playlists are possible ?
Proof -
Given that he wants to play no more that 4 reggae songs.
So the possibility of choice of reggae song is 0, 1, 2, 3, 4
Now,
Case I -
If 0 reggae song is selected
⇒All 10 songs selected from 7 blue, 7 disco, 5 pop,
Number of ways = ¹⁹C₁₀ ₓ ⁷C₀ = 92,378
Case II -
If 1 reggae song is selected
⇒All 9 songs selected from 7 blue, 7 disco, 5 pop,
Number of ways = ¹⁹C₉ ₓ ⁷C₁ = 646,646
Case III -
If 2 reggae song is selected
⇒All 8 songs selected from 7 blue, 7 disco, 5 pop,
Number of ways = ¹⁹C₈ ₓ ⁷C₂ = 1,587,222
Case IV -
If 3 reggae song is selected
⇒All 7 songs selected from 7 blue, 7 disco, 5 pop,
Number of ways = ¹⁹C₇ ₓ ⁷C₃ = 1,763,580
Case V -
If 4 reggae song is selected
⇒All 6 songs selected from 7 blue, 7 disco, 5 pop,
Number of ways = ¹⁹C₆ ₓ ⁷C₄ = 949,620
So,
Total possible ways = 92,378+ 646,646+ 1,587,222+ 1,763,580+ 949,620
= 5,039,446
⇒Total possible ways = 5,039,446
Now,
Also the 10 songs selected can arranged themselves in 10! ways. ( because order of song played does not matter )
∴ we get
Different playlists possible = 10! × 5,039,446
= 18287141644800
⇒Different playlists possible = 18287141644800
Type 3 values for x that make this statement true, “x is less than or equal to 0”
Type 3 values for y that make this statement true, “ y is greater than or equal to -2”
Type 3 values for z that make this statement true, “z is less than or equal to 4”
Answer:
1.) x= -1,-2,-3
2.) y= -2,-1,0
3.) z= 4, 3, 2
Step-by-step explanation:
1.) The number being negative makes them less than zero
2.) The numbers are equal to -2 or greater, since with negative numbers the symbol for the letter may seem like it is decreasing, but that would only be the case if it was positive, as a negative, it works backwards.
3.) The numbers are less than or equal to 4
evaluate in the following expression when x = 4 and y = 5

A book weighs 1/3 pound. How much do 4 books weigh?
Using the unitary method, if the weight of a book is [tex]\frac{1}{3}[/tex] pound, then the weight of 4 books is [tex]\frac{4}{3}[/tex]
What is unitary method?"The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value."
Apply unitary method
Weight of 1 book = [tex]\frac{1}{3}[/tex]
Weight of 4 books = [tex]4(\frac{1}{3})[/tex]
Hence, the weight of 4 books is [tex]\frac{4}{3}[/tex]

He earns $25 per hour for training and $15 per hour for data entry support. Steven can work no more than 40 hours a week. He wants to use linear programming techniques to optimize his income. Part A Construct a model to represent the amount of time Steven can spend on data entry and training. Be sure to define your variables. Sketch a graph of your model. Part B While Steven would like to spend most of his time training, the number of hours spent training cannot exceed twice the number of hours doing data entry support. Steven must spend at least 10 hours each week on data support. Construct a model to show the constraints. Sketch a graph of your model. Part C Find the vertices of the feasible region. Show your work or explain how you found the coordinates. Part D What is the maximum possible amount of money Steven can earn in a week given the constraints? Round to the nearest dollar. Validate your solution to assess the reasonableness of you Part E The number of hours Steven worked one week resulted in a gross income of $800. From this, a portion was withheld for benefits, retirement, and taxes. The total amount withheld from Steven’s check was $264. The amount withheld for taxes was twice the amount withheld for retirement, and the amount withheld for benefits was $24 less than the sum of retirement and taxes. Construct a system of equations that can be used to find the amount of benefits, retirement, and taxes. Be sure to define your variables. Part F Solve the system from Part E. Validate your solution to assess the reasonableness of your model.
