hi there !

a supplementary angle is equal to 180⁰

a supplementary angle is equal to 180⁰ they are angles on a straight line / flat line

a supplementary angle is equal to 180⁰ they are angles on a straight line / flat lineif you want to find a missing angle in a supplementary angle then you have to subtract the given angles by 180⁰

hope this helps and please ask if you have any questions :)

URGENT!!! I NEED MATH HELP ASAP!!! I don't understand this assignment at all! It has 5 parts, the first four are charts or graph

Vika [28.1K]

First off, 23+12 isn't 45.

Anyways, Part A, graphing should be pretty simple, just match the corresponding values together as shown by the table on the left. For example, for the crop size that says "200," go up to where the value is seven, and mark it.

The function is also not that hard. Make "x" equal the value of the crop size. (Square yards) Thus for "x" crop size, the function B(x) = 3.5/100.

Part B
W(x) = 60*x

For the completing the table, just plug in some values for "x" (remember "x" is "Bushels of corn in a shipment") like 1, 2, 3, 4 etc, and write the corresponding output next to it.

Part C
The given information literally tells you the answer. P(x) = 4x. That's ur function. So for the graph, say "x" ("Bushels of Corn") is 1, than the corresponding "y" value ("Selling Price") is 4, since P(x) = 4*x.

As for completing the table, once again, just write in several values, geez. For example, "Bushels of Corn" = 5, than "Selling Price" = 20.

The function basically is the key to all the answers. 

Part D
Alright, remember, once you get the function, you have all the answers. 5 Bushels of corn equals 14 gallons of ethanol, so the function is 
E(x) = 14/5. (And remember, the "x" value is "bushels of corn")

The table and graph are easy to do, since you know the function, however the "y" axis values on the graph are kind of challenging to deal with, but I have faith that you can estimate and mark the values close enough.

Here's my best explanation for Part E,

Proportional relationships have graphs that always pass through the origin of a graph, while non-proportional graphs don't. And also, proportional relationships always have consistent ratios, while non-proportional relationships don't. And for their equations, proportional relationships equations are always one step, (Ex: y = 5x) while non proportional equations are two-step equations, which means they contain a constant value that is added or subtracted on the left side. (Ex: y = 3x - 12)

Use a separate sheet of paper to solve the system of inequalities by graphing. Use the graph to decide if the point (1, –1) is i

Lena [83]

Answer:

The answer is no though, the point (1,-1) is below both.

Step-by-step explanation:

So the two inequalities are y≤-3x+3 and 3x+8y≥3

With inequalities you have to know a few things. First, when you graph you may have to use non solid lines. for instance, if you had x<5, 5 would not be part of the answer because it is only answers less than 5. so you represent this by making a dashed line that says "you cannot include values on this line". Second, with algebra, if you multiply both sides by a negative it flips the inequality. for instance -y > 54 you would multiply (or divide) by -1 and it would change to y < -54. Third, when graphing an inequality, treat it like an equation and graph the line as if it were said equation(with solid or dashed lines as needed) then, if it is y > f(x) you shade in the section above the line and y < f(x) shades in below. The shaded part is your answer basically. Now lets get into yours.

y≤-3x+3

It is already in the form y = f(x) so grapht he line 3x + 3 with a solid line since it is y is less than or equal to, then shade below that line.

3x+8y≥3

First get it so y is by itself

3x+8y≥3

8y≥3 - 3x

y ≥ 3/8 - 3/8 x

Now grapht his line with a solid line and shade the area above it.

Now, the shaded area below between y ≥ 3/8 - 3/8 x and y≤-3x+3 and the lines are your answer, so you need to check if the point (1, -1) is in this shared shaded area or on one of the lines.

The answer is no though, the point (1,-1) is below both.

A GROUP OF STATISTICS STUDENTS DECIDED TO CONDUCT A SURVEY AT THEIR UNIVERSITY TO FIND THE AVERAGE (MEAN) AMOUNT OF TIME STUDENT

Kay [80]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

n = 240

mean = 22.3 hours

standard deviation = 6 hours

At 99% level of confidence, z = 2.58

So, interval would be

$\bar{x}\pm z\dfrac{\sigma}{\sqrt{n}}\\\\=22.3\pm 2.58\times \dfrac{6}{\sqrt{240}}\\\\=22.3\pm 0.99\\\\=(22.3-0.99,22.3+0.99)\\\\=(21.31,23.29)$

Hence, Option 'c' is correct.
