sssssssssssssssssssssssssssssssssssssssssssssssssssssssss
anybody know the answer?
Answer:
Step-by-step explanation:
You can read f(x) to mean y. y is above the x axis between -2 and - 6. To put it more formally,
-6 <x <-2
Why don't you use ≤ ?
It's because where is f(x) positive? 0 is not a positive value,, so you cannot use the endpoints.
Using euler's formula how many edges does a polyhedron with 7 faces and 7 vertices have
Answer:
12 Edges
Step-by-step explanation:
Top one is right but had 2 stars for some reason. 12 Edges is the answer. (Just did it btw)
Edges of a polyhedron are 12.
What is polyhedron?"Polyhedron is a three dimensional solid shape with a certain number of faces, edges and vertices.
If the number of faces and the vertex of a polyhedron are given, we can find the edges using the polyhedron formula. This formula is also known as ‘Euler’s formula’."
F + V = E + 2
Here,
F = Number of faces of the polyhedron
V = Number of vertices of the polyhedron
E = Number of edges of the polyhedron
Given
Number of Faces (F) = 7
Number of Vertices (V) = 7
For any polyhedron,
Euler's Formula:
F + V - E = 2
⇒ 7 + 7 - E = 2
⇒ 14 - E = 2
⇒ E = 14 - 2
⇒ E = 12
Number of Edges (E) = 12
Hence, Edges of a polyhedron are 12.

Julio is paid 1.2 times his normal hourly rate for each hour he works over 31 hours in a
week. Last week he worked 35 hours and earned $486.88.
Enter and solve an equation to find Julio's normal hourly rate, r. Complete the explanation
how you know that your answer is reasonable.
9514 1404 393
Answer:
$13.60
Step-by-step explanation:
Julio worked 35 -31 = 4 overtime hours. For those 4 hours, he was paid at the rate 1.2r. Then his earnings were ...
31r +4(1.2r) = 486.88
35.8r = 486.88
r = 486.88/35.8 = 13.60
Julio's normal hourly rate is $13.60.
_____
Why do we believe this is reasonable?
35.8 is a reasonable number of hours to be paid for, considering that each of the 4 hours of overtime effectively adds 0.2 hours of straight-time pay, for a total of 35 +4(0.2) = 35.8 hoursthe pay rate is an integer number of cents per hour, and is in the right ballpark between 480/30 = $16 per hour and 480/40 = $12 per hour.we can check the numbers to verify: 31×$13.60 +4×1.2×$13.60 = $421.60 +4×16.32 = $486.88.PLease help i will give extra points

A survey of 300 people found that 60 owned an iPhone, 75 owned a Blackberry, and 30 owned an Android phone. Furthermore, 40 owned both an iPhone and a Blackberry, 12 owned both an iPhone and an Android phone, and 8 owned a Blackberry and an Android phone. Finally, 3 owned all three phones. (a) How many people surveyed owned none of the three phones? (b) How many people owned a Blackberry but not an iPhone? (c) How many owned a Blackberry but not an Android?
Step-by-step explanation:
We let A be the set of those who owned an iPhone, B be the set of those who owned a Blackberry,
and C those that owned an Android. Therefore we have |A| = 60, |B| = 75, and |C| = 30. Also,
we know that |A ∩ B| = 40, |A ∩ C| = 12 and |B ∩ C| = 8. Finally, |A ∩ B ∩ C| = 3. Therefore,
by the principle of inclusion/exclusion, we have
|A ∪ B ∪ C| = |A| + |B| + |C| − |A ∩ B| − |A ∩ C| − |B ∩ C| + |A ∩ B ∩ C|
= 60 + 75 + 30 − 40 − 12 − 8 + 4
= 109
(a) Since there are 300 total people, there are 191 without one of the types of phone.
(b) Since |A ∩ B| = 40 and |B| = 75, there are 35 people with a Blackberry that don’t own
an iPhone.
(c) Since |B ∩ C| = 8 and |B| = 75, there are 67 people with a Blackberry that don’t own
an Android.

Which graph shows a function whose inverse is also a function?
Step-by-step explanation:
Using the concept of inverse function, it is found that the first graph shows a function whose inverse is also a function.
----------------------------------------
A function f(x) will only have an inverse function if: f(a) = f(b) \leftrightarrow a = bf(a)=f(b)↔a=b , that is, a value of y will have only one respective value of x.
----------------------------------------
In the first graph, for each value of y, there is only one value of x, so the inverse is also a function, and this is the correct option.
In the second graph, for example, y = 0 when x = -1 and when x = 1, so the inverse is not a function.
In the third graph, for example, y = -3 when x = 0 and x = 2, so the inverse is not a function.
In the fourth graph, for example, y = 1 for two values of x, so the inverse is not a function.
A researcher is interested in the mean mileage for all school buses in a school district. Forty buses are randomly selected from a computer printout that contains every bus in the district. For each bus they record the name of the school it is used for, mileage, and age. It is calculated that 32.5% of the 40 buses are over 15 years old. With 99% confidence they find that the mean mileage for all school buses in the school district is between 85,261 and 134,890 miles.What is the qualitative variable in this study
Using classification of variables, it is found that the qualitative variable in this study is the name of the school the bus is used for.
-----------------------------
Variables may be classified as quantitative or qualitative.
A variable is quantitative if it assumes numerical values, for example 1,2,3. If it assumes "labels", for example good or bad, it is qualitative.-----------------------------
In this question, the variables are:
School name, which is qualitative.Mileage, which is quantitative.Age, which is quantitative.Thus, the qualitative variable is the school name.

usa a straightedge and a compass to construct a segment of length ab+cd ILL GIVE BRAINLIEST
Step-by-step explanation:
To create a perpendicular bisector, you need a compass, a straightedge, and a pencil. As well as the line segment AB drew down.
1> You start by opening the compass and stretching it to a width greater than half the length of AB.
2> Then you simply place one point of the compass on the line segments A. From here, you move the compass and draw arcs above and below the line AB.
3> Without moving the compass measure, remove it from point A and place it onto point B. You basically repeat step 2 by drawing arcs above and below the line again.
4> If you've done it right, the arcs should be in the middle, X and Y, and using a straightedge/ruler you draw a line that goes vertically through where they connect.
and that should be your perpendicular bisector using segment AB.

the bake sale and spent $175 on supplies. What was their overall profit?
9514 1404 393
Answer:
-$25 (a loss of $25)
Step-by-step explanation:
Profit is the difference between revenue and cost.
profit = $150 -175 = -$25
The cheerleaders took a $25 loss on their bake sale.

Additional comment
The wording "made $150" can be interpreted two ways. We have taken it to mean the revenue from sales was $150. The same wording could also be used to indicate the profit was $150.

This pool has a deep end and a shallow end.The pools perimeter is 70 ft.Hiw wide is the deep end,d?
Work Shown:
L = d+9 = length along the horizontal
W = 10 feet = width along the vertical
P = 2(L+W) = perimeter of rectangle = 70 feet
70 = 2(d+9+10)
70/2 = d+19
35 = d+19
d+19 = 35
d = 35-19
d = 16
The deep end is 16 feet wide
