Consider the table showing the given, predicted, and residual values for a data set.
A 4-column table with 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled given with entries negative 1.6, 2.2, 4.5, 6.1. The third column is labeled predicted value with entries negative 1.2, 1.5, 4.7, 6.7. The fourth column is labeled residual value with entries negative 0.4, 0.7, negative 0.2, negative 0.6.
Which point would be on the residual plot of the data?
Answer:
(4, -0.6)
Step-by-step explanation:
The table is:
x Given Predicted Residual value
1 -1.6 -1.2 0.4
2 2.2 1.5 0.7
3 4.5 4.7 -0.2
4 6.1 6.7 -0.6
The points on the residual plot must be the pairs (x, residual value). This is:
(1, 0.4)
(2, 0.7)
(3, -0.2)
(4, -0.6)
Thus, the correct choice is the last one: (4, -0.6)
The point that would be on the residual plot of the data is (4, -0.6). See the explanation below.
What is a residual plot?A residual plot is a graph in which the residuals are displayed on the vertical axis and the explanatory variables is displayed on the horizontal axis.
From the analysis of the table attached, we have the following points on the residual plot:
(1, 0.4)
(2, 0.7)
(3, -0.2)
(4, -0.6)
Point on the residual plot must include the point on x and a residual value, hence, the correct answer is (4, -0.6).

II'll mark brainliest who is the first to answer both questions correctly.
A)
You take the four Aces, four 2's, and four 3's from a standard deck of 52 cards, forming a set of 12 cards. You then deal all 12 cards at random to four players, so that each player gets three cards. What is the probability that each player gets an Ace, a 2, and a 3?
B)
In the SuperLottery, three balls are drawn (at random) from ten white balls numbered from 1 to 10, and one SuperBall is drawn (at random) from ten red balls numbered from 11 to 20. When you buy a ticket, you choose three numbers from 1 to 10, and one number from 11 to 20.
Answer:
A) The probability that each player gets an ace, a 2 and a 3 with the order unimportant = (72/1925) = 0.0374
B) The probability of winning the jackpot = (1/1200) = 0.0008333
Step-by-step explanation:
A) There are four Aces, four 2's, and four 3's, forming a set of 12 cards
These cards are to be divided at random between 4 players.
What is the probability that each player gets an ace, a 2 and a 3.
We start with the first player, the probability of these cards for the first player, with order not important (because order isn't important, there are 6 different arrangement of the 3 cards)
6 × (4/12) × (4/11) × (4/10) = (16/55)
Then the second player getting that same order of cards
6 × (3/9) × (3/8) × (3/7) = (9/28)
Third player
6 × (2/6) × (2/5) × (2/4) = (2/5)
Fourth player
6 × (1/3) × (1/2) × (1/1) = 1
Probability that each of the players get different cards is then a multiple of the probabilities obtained above
= (16/55) × (9/28) × (2/5) × 1
= (288/7700) = (72/1925) = 0.0374
B) The concluding part of the B question.
To win the jackpot, the numbers on your ticket must match the three white balls and the SuperBall. (You don't need to match the white balls in order). If you buy a ticket, what is your probability of winning the jackpot?
Probability of wimning the jackpot is a product the probability of getting the 3 white balls correctly (order unimportant) and the probability of picking the right red superball
Probability of picking 3 white balls from 10
First slot, any of the 3 lucky numbers can fill this slot, (3/10)
Second slot, only 2 remaining lucky numbers can fill this slot, (2/9)
Third slot, only 1 remaining lucky number can fill this slot, (1/8)
(3/10) × (2/9) × (1/8) = (1/120)
Probability of picking the right red superball
(1/10)
Probability of winning the jackpot = (1/120) × (1/10) = (1/120) × (1/10) = (1/1200) = 0.0008333

The price of gasoline increased 25% from July to August. If c = cost of gasoline in July, write two expressions that represent the price of gas in August. If you know the cost of gas in July, which expression do you think would be easier to use to calculate the cost of gas in August and why?
Answer:
Wrote it in the explanation :)
Step-by-step explanation:
Expression One: c + 25% = price of gas in august
Expression Two: c + 0.25 = price of gas in august
Expression Two would be easier to use if we knew "c" because the numbers are already in decimal form. If it were in percentage form, it would cause us an extra step to convert it into a decimal.

What is the answer for this for a graph 3j>6
First divide both sides of the inequality by 3.
On the left, the 3's cancel and you're left with j
and on the right, 6 divided by 3 is 2.
So we have j >2 which is the solution to this inequality.
I have graphed the inequality for you below.
Start with an open dot on 2.
We use an open dot because j > 2 but it is not equal to 2.
Then draw an arrow to the left to

Aisha wants to paint the four walls of her living room. Each wall is 2.1 m high and 4.5 m long. One wall has a door of 1.8 m by 0.9 m. Tins of paint cost £10 per 1.5 L tin. Each litre of paint can cover 12 m2 of wall. There is an offer of: Buy 2 tins get the 3rd at half price. How much will Aisha pay to paint her living room?
Answer:
£25 or £20.10
Step-by-step explanation:
calculate the area to be painted:
2.1x4.5= 9.45m^2 for each wall
x4= 37.8m^2
area of door= 1.8x0.9= 1.62m^2
subtract the area of the door from the wall area
37.8-1.62= 36.18m^2 to be painted
divide the area by the area that 1L of paint can cover
16.18/12= 3.015 L needed
if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L- so another can (3 cans total) add price up.
£30- but buy 2 get 3rd 1/2 price, so take £5 off. price is £25
or
calculate price for 0.015L
1.5=£10
divide both sides by 100
0.015= £ 0.10
if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L
£20+£0.10= £20.10

2. Determine if the two quadrilaterals are similar,
if they are, state the scale factor.
Answer:
Yes, they are similar. The scale factor is 5/3
Step-by-step explanation:
The longest to the shortest side of quadrilateral KLMJ are: JM, ML, KJ, LK
The longest to the shortest side of quadrilateral QPSR are: QP, PS, RQ, SR
If the two quadrilaterals are similar, the following proportion must be satisfied:
JM = k*QP
ML = k*PS
KJ = k*RQ
LK = k*SR
where k is the scale factor. Solving for k and replacing with lengths:
k = 25/15 = 24/14.4 = 20/12 = 15/9 = 5/3
From the figure, we can also see that:
∠M ≅ ∠P
∠L ≅ ∠S
∠R ≅ ∠K
∠Q ≅ ∠J
Therefore, the two quadrilaterals are similar.

to determine the inverse of the given function change f(x) to y switch and y and solve for
Answer:
x, y, 4, 0
Step-by-step explanation:
To determine the inverse of the given function change f(x) to y switch x and y and solve for y.
f(x) = sqrt(x - 4)
y = sqrt(x - 4)
x = sqrt(y - 4)
x^2 = y - 4
x^2 + 4 = y
y = x^2 + 4
The domain of the inverse is the same as the range of the original function.
inverse f(x) = x^2 + 4
x^2 + 4 >= 4
x^2 >= 0
x >= 0
The resulting function can be written as inverse f(x) = x^4 + 4, where x >= 0.

Answer:
Yes, because it passes the vertical line test
Step-by-step explanation:
A function has one output for each input. This is called a one to one correspondent. This is shown by the vertical line test
This graph passes the vertical line test and is therefore a function
Answer:
D
Step-by-step explanation:
The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.
-------------------------------------------------------------------------------------------
Example: The first table is a function because each input value has only 1 output value, but the second table has more that one output value per input. (View Attached Picture Below)
The input value 4 in Table A has only 1 output value, 20. But in Table B, the input value for 4 has 2 output values, 16 and 17. So Table A is a function, while Table B is not.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The product of the two resulting integers is 80.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Let the unknown integer be represented by x. Given that the sum of two consecutive integers is -15. Therefore, we can write,
x + (x+1) = -15
2x + 1 = -15
2x = -16
x = -8
Thus, the smaller integer is -9 and the larger integer is -8.
Now, If 1 is added to the smaller integer and 2 is subtracted from the larger integer.
Smaller Interger = -9 + 1 = -8
Larger Integer = -8 - 2 = -10
Further, the product of the two resulting integers is,
Product = -8 × -10
= 80
Hence, the product of the two resulting integers is 80.

The coordinate grid shows points a through k. Which points are solutions to the system of inequalities 2x+y 8 please help this is my last resort
Answer:
The points that verify the system of inequalities are:
point E, pointF, and point G.
Step-by-step explanation:
Please see the attached image that illustrates the boundary lines in your system of inequalities.
The boundary line for the inequality [tex]2x+y<10[/tex] is depicted in green, while the boundary line for the inequality [tex]2x-4y>8[/tex] is depicted in red.
By solving for y in each inequality, we understand which half-plane should be considered for the inequality:
First inequality (green boundary line) :
[tex]2x+y<10\\y=10-2x[/tex]
This means that we are to consider the points below the green boundary line.
Second inequality (red boundary line) :
[tex]2x-4y >8\\2x-8>4y\\y<\frac{1}{2} x-2[/tex]
This means we have to consider the points below the red boundary line.
Recall as well that both conditions we arrived at have to be satisfied by the points that are solutions of both inequalities.
From the image, we can see that there are only three points that reside at the same time below the green and the red boundary lines. These points are: point E, pointF, and point G.
On the other hand, we have two points that lie on a boundary line (point J and H), but they should be ignored, since the system of inequalities contain just inequality symbols < or >, and not the "equal" sign.
