The first graph that we have in this question is the graph that can be used to model the relationship that we have in this table.
How to model the graph in the tableIn this table we can see that what we are having is a linear equation. First we have to check the slope that lies in any two of the points
This would be;
( 112.5- 75) / ( 3- 2) = 37.5 and
( 150 -112.50) / ( 4-3) = 37.50
We can have the equation of a straight line as: y = mx + c
y = 37.50x + c, x = 2
then c = 75 - 75 =0
When plotted on the graph we would have the first graph as the best solution. Hence option 1 is right

Anna is in charge of the alumni fundraiser for her alma mater. She is selling pre-sale tickets for $10 and at-the-door tickets for $20. The venue has the capacity to hold 400 people. The graph represents the number of tickets Anna needs to sell to offset her upfront costs and raise $5,000 for her school
A.400
B.300
C.250
D.100
Number of At-the-Door tickets Anna needs to sell to make her goal = 100
Anna is selling pre-sale and at-the-door tickets.
Let 'x' be the number of pre-sale tickets and 'y' be the number of at-the-door tickets.
Price of a pre-sale ticket = $10
Price of an at-the-door ticket = $20
Total price to be raised = $5000
So the equation corresponding is 10x+20y = 5000-----------(1)
Total number of people the venue can hold = 400
Thus the next equation is x+ y = 400---------(2)
From the graph the line with points (0,250) and (500,0) represent the equation (1) since 10 x 0 + 20 x 250 = 5000 and 10 x 500 + 20 x 0 = 5000.
The line with points (0,400) and (400,0) represent the equation (2) as 0+400 = 400 and 400+0 = 400.
So to find x and y we need to solve equations (1) and (2).
10 x (2) ⇒ 10x+10y = 4000-------(3)
Now subtract (3) from (1)
⇒ 10y = 1000
⇒ y = 100
Hence the number of At-the-Door tickets Anna needs to sell to make her goal = 100

Six Sigma process
What is Six Sigma?The phrase "Six Sigma" refers to a collection of quality-control methods that organisations can utilise to get rid of flaws and enhance operations so as to increase productivity and revenues. A scientist created it in the 1980s while he was employed by Motorola.
A statistical and data-driven technique called Six Sigma examines small errors or flaws. It places a focus on cycle-time gains while lowering manufacturing faults to no more than 3.4 incidents per million units or events. The fact that only 3.4 out of a million events along a bell curve will deviate by more than six standard deviations indicates that an error usually occurs with an event that deviates by six standard deviations from the mean.

Which of the following inequalities would be graphed with an open circle?
3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.
Open circle is a term used for numbers that are less than (<) or greater than (>). On the other hand, Closed circle is used for numbers that are less than or equal to (≤ ) and greater than or equal to (≥).
Here, we are given four inequalities, let us check them one by one-
A. h + 6 > -3h + 12
⇒ 4h > 6
or h > 3/2
Here, we see that there is no equality sign, this means that 3/2 won't be included and hence h + 6 > -3h + 12 would be an open circle inequality.
B. 7 ≥ d/3
⇒ d ≤ 21
Here, we can clearly see the equality sign which means that 21 will be included. Hence, 7 ≥ d/3 would not be graphed with an open circle.
C. 3(x - 2) < 18
x - 2 < 6
x < 8
Here, we see that there is no equality sign, this means that 8 won't be included and hence 3(x - 2) < 18 would be graphed with an open circle.
D. 2y ≤ 14
y ≤ 7
Here, we can clearly see the equality sign which means that 7 will be included. Hence, 2y ≤ 14 would not be graphed with an open circle.
Thus, 3(x - 2) < 18 and h + 6 > -3h + 12 would be graphed with an open circle.

Proportion of females who have less than 3 close friend working note
What is the statistical median?
The midway number in a set of data is known as the median. The data should first be arranged and ranked from smallest to greatest. Divide the total number of observations by two to get the midway value. The value in that location is the median if there are an odd number of observations; otherwise, round the number up.(a) Mean =1.04
Median=1
assuming the number of close friends as a whole value, our mean is also 1.
the distribution is roughly symmetric. because mean is approximately equal to median.
The explanation is provided in the image attached above;
Answer (b)Median number of a close friend for females is 1.
The calculation for median is provided in the image.
Answer(c) According to the shape of the distribution as we have observed from the data we can say that the median calculated for close friends of females is the same as the mean number of close friends for men.
Here we are not assuming the number of close friends in decimal(because it is not a continous variable).
Answer (d) P(less than 3) = P(0) + P(1) + P(2)
= 0.353+0.368+0.191=0.912

-4x+3y=1
6x-y=2
Answer: x=0.5, y=1
Step-by-step explanation:
-4x+3y=1
6x-y=2
6x-2=y
-4x+3(6x-2)=1
-4x+18x-6=1
-4x+18x=7
14x=7
x=0.5
6x-y=2
6(0.5)-y=2
3-y=2
y=1
Let's change the equation,
→ 6x - y = 2
→ y = 6x - 2
Then the value of x will be,
→ -4x + 3y = 1
→ -4x + 3(6x - 2) = 1
→ -4x + 18x - 6 = 1
→ 14x = 1 + 6
→ x = 7/14
→ [ x = 1/2 ]
Hence, the value of x is 1/2 (or) 0.5.
Now the value of y will be,
→ y = 6x - 2
→ y = 6(1/2) - 2
→ y = 3 - 2
→ [ y = 1 ]
Hence, the value of y is 1.

Given f(x) = 3x+9 and g(x) = 5x-1, find f(g(x)).
Step-by-step explanation:
In this equation, given
f(x) = 3x + 9 and g(x) = 5x -1
So the question is what is the value of f if we put the value of g(x) in f(x)
So to solve the equation we need to replace the value of x in f(x) with g(x)
So it was obtained as below
f(g(x)) = 3(5x-1) + 9
= (15 x - 3) + 9
= 15 x + 6

I would like to know how to find the percentage number of these increased numbers if that makes any sense at all
I will use the example that they gave to describe the method
First, you need to find the difference between the new amount and the original amount. The new one is 30, while the original one is 24, so the original amount incrased by 6.
Now, you take the difference that you got, and divide it by the original amount. 6 : 24 = 1/4, or 25%. So, the percentage increase is 25%
Applying the same for the others :
32 -> 56 (increased by 24, 24:32 = 3/4 -> 75%)
15 -> 18 (increased by 3, 3:15 = 1/5 -> 20%)
30 -> 33 (increased by 3, 3:30 = 1/10 -> 10%)
150 -> 153 (increased by 3, 3:150 = 1/50 -> 2%)
120 -> 126 (increased by 6, 6:120 = 1/20 -> 5%)
200 -> 202 (increased by 2, 2:200 = 1/100 -> 1%)
