An appliance store sells microwave ovens and has many different styles to choose from. A handout from the store contains details about brand, price, number of power settings, and color. What are the individuals in this data set?
a) microwave ovens
b) brands
c) prices
d) colors
Answer:
a) microwave ovens
Step-by-step explanation:
Since we don't know what the dataset is, we cannot say with certainty what its elements are. The first sentence talks about microwave ovens, so it may be reasonable to assume that will be the members of the data set.
_____
Additional comments
In computer programming terms (as for a shopping web site, for example), the data set would consist of tuples of ...
(brand, price, number of power settings, color)
and perhaps other attributes, such as dimensions, home/commercial, length of warranty, and more. That is, the appropriate answer would be "all of the above."

Answer:
A
Step-by-step explanation:
Which of these relations is a function?
Why is this? This is the only relation that passes the vertical line test.
The other choices have situations where we can draw a single straight vertical line through more than one point on the blue curve. That means the graph fails the vertical line test and we do not have a function.
For a function to be possible, any x input must lead to exactly one y output.

What is the slope of the line that passes through the pair of points?
( 1,7 ) , ( 10,1 )
Answer:
m = -2/3
Step-by-step explanation:
We can find the slope of the line from the given two points:
m = (y2-y1)/(x2-x1)
m = (1-7)/(10-1)
m = -6/9
m = -2/3

A total of 4500 tickets to a concert were sold and the price for each ticket was either $59 or $85. If the
amount collected was $291, 500, how many tickets were sold at each price?
O (35, 10)
O (3500, 1000)
O (1000, 2200)
O (3000, 1500)
Answer:
3500 tickets were sold at $59
1000 tickets were sold at $85
(3500, 1000)
Step-by-step explanation:
x + y = 4500
59x + 85y = 291500
x + y = 4500
x = 4500 - y
59(4500 - y) + 85y = 291500
265500 - 59y + 85y = 291500
265500 + 26y = 291500
26y = 26000
y = 1000
x + y = 4500
x + 1000 = 4500
x = 3500
Check:
x + y = 4500
3500 + 1000 = 4500
4500 = 4500
59x + 85y = 291500
59(3500) + 85(1000) = 291500
206500 + 85000 = 291500
291500 = 291500

A. (4, 8, 16) C. (8, 16, 4)
B. (4, 8, 12) D. (12, 6, 8)
Answer: C. (8, 16, 4)
Step-by-step explanation:
Given the following:
Let:
Trucks = T ; Cars = C ; SUVs = S
T =0.5(C + S) - 2 - - - (1)
C = 2T - - - (2)
T + C + S = 28 - - - (3)
T = 0.5(2T + S) - 2
T = T + 0.5S - 2
0 = 0.5S - 2
0.5S = 2
S = 2/0.5
S = 4
From T + C + S = 28
C = 2 T ; S = 4
T + 2T + 4 = 28
3T = 28 - 4
3T = 24
T = 24/3
T = 8
From T + C + S = 28
8 + C + 4 = 28
12 + C = 28
C = 28 - 12
C = 16
Hence, (T, C, S) = (8, 16, 4)

Solve 4x – 2(x + 1) = 3x + 10.
Answer:
x=-12
Step-by-step explanation:
4x−2(x+1)=3x+10
Step 1: Simplify both sides of the equation.
4x−2(x+1)=3x+10
4x+(−2)(x)+(−2)(1)=3x+10(Distribute)
4x+−2x+−2=3x+10
(4x+−2x)+(−2)=3x+10(Combine Like Terms)
2x+−2=3x+10
2x−2=3x+10
Step 2: Subtract 3x from both sides.
2x−2−3x=3x+10−3x
−x−2=10
Step 3: Add 2 to both sides.
−x−2+2=10+2
−x=12
Step 4: Divide both sides by -1.
−x/−1=12/−1
x=−12
Answer:
x=−12
Answer:
x=-12
Step-by-step explanation:
4x-2x-2=3x+10
2x-2=3x+10
2x-2+2=3x+10+2
2x=3x+12
2x-3x=3x+12-3x
-x=12
-x/-1 = 12/-1
x= -12
3=−2 |14s−5| +3 can i get a simple explination im kind of dumb lol
Answer:
s=5/14
Step-by-step explanation:
cancel equal terms on both sides of the equation
0=-2 x |14s-5|
swap the sides of the equation
-2 x |14s-5|=0
divide both sides of the equation by -2
|14s-5|=0
when the absolute value of 14s-5= 0, then 14s-5=0
move the constant to the right-hand side and change its sign
14s=5
now divide both sides of the equation by 14
s=5/14

Mai uses Triangle A and says the slope of this line is 6/4.
Elena uses Triangle B and says no, the slope of this line is 1.5.
Do you agree with either of them? Explain.
The slope of the line is the ratio of the rise to the run, or rise divided by the run. Yes i can agree with both of their statements.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
As we know that the slope of a line will be always same on a given line. If slope triangle A has slope 6/4. Then triangle B will be also have the same slope.
As both triangles are connected to the same line. These two triangles A and B will have same slopes.
Mai uses Triangle A and says the slope of this line is 6/4.
If we convert fraction 6/4 to decimal we get 1.5 value.
So i agree with both of their statements.

find the value of x
The answer is 40.
I need to show my work
Answer:
(2x+7)° + (5x+4)° + 69° = 360°
=> 2x + 7 + 5x + 4 + 69 = 360
=> 7x + 80 = 360
=> 7x = 360 – 80
=> x = 280/7
=> x = 40
Answer:
x=40
Step-by-step explanation:
(2x+7)*+(5x+4)*+69*=360* (360* because its a circle)
7x+80=360 (combine like terms)
- 80 -80 (minus 80 both sides)
7x=280 (divide 7 both sides)

Susan can read 72 words in One-third of a minute. Which statement is correct? She can read 24 words per minute, because 72 divided by One-third is equal to 24. She can read 24 words per minute, because 72 times One-third is equal to 24. She can read 216 words per minute, because 72 divided by One-third is equal to 216. She can read 216 words per minute, because 72 times One-third is equal to 216.
Answer:
The answer is
"She can read 216 words per minute because 72 divided by One-third is equal to 216."
Step-by-step explanation:
Given the statement
Susan can read 72 words in One-third of a minute ....pause
Whats is one-third of a minute
it is expressed as 1/3*60=20sec
so Susan can read 72 words in 20 second
this means that in a minute she can read
72+72+72 words= 216 word since 20sec*3 is 1 minute
alternatively

Two angles are supplementary. If one angle measures twice the other, and the number of degrees in the smaller angle.
Answer:
60 Degrees
Step-by-step explanation:
Supplementary means it equals 180 together, so you divide it by 3 because the one is twice as big and you take the smaller answer
[tex]\frac{180}{3} =60[/tex]
Small and large angle are 60° and 120°.
Given that;
Angles are supplementary
Computation:
Assume;
Smaller angle = a
So,
Large angle = 2a
So,
In supplementary
a + b = 180
a + 2a = 180
3a = 180
a = 60
Smaller angle = 60°
Large angle = 2(60)
Large angle = 180°

Kaitlyn is making big goods for charity bake sale he places a tray of scones a tray of muffins and a tray of cookies in the oven discounts bake for 15 minutes the muffins bake for 12 minutes and the cookies bake for 10 minutes when one trays done he removes it and replace it with another tray at the same I don't how many minutes after kaylan put the trays in the oven when he 1st remove the scones muffins and cookies at the same time
Answer:
So:
Counting from a given time t = 0min, we know that:
Each 15 mins she removes the scones
Each 12 mins she removes the muffins
Each 10 mins she removes the cookies.
So when will she remove both at the same time?
Well, this will happen in the smallest common multiple of 15, 12 and 10.
or at LCM(10, 12, 15).
How we find it?
well, in this case is easy.
All the multiples of 10 end with a zero.
So let's find the multiples of 12 and 15 that also end with a zero:
12*6 = 60
15*4 = 60
and
10*6 = 60
So the LCM(10,12,15) = 60.
Another way is by calculating:
10*12*15/(GCF(10,12)*GCM(12,15)*GCM(10,15)
Where GCF = greatest common factor.
Between 10 and 12 is 2.
Between 12 and 15 is 3
Between 10 and 15 is 5.
Then:
10*12*15/(2*3*5) = 60.
This means that 60 minutes after she starts, she will remove the scones, muffins and cookies at the same time.
