Page 5. 5, 6, 7, 8
Page 6. 12.5
Page 7. 4(3x)
Page 8. 0, 4
i don't know number 7
Answer:
9, 10
12.5
4 + 3x
0, 4
Step-by-step explanation:
5. This just looks to be some simple multiplication so lets work this out 1 by 1 .
Plugging each answer possible into m this is what we get :
8 x 5 = 40
8 x 6 = 48
8 x 7 = 56
8 x 8 = 64
8 x 9 = 72
8 x 10 = 80
Considering these answers lets find which ones are GREATER than 67.
That would be :
72, 80
So your answers would be :
9, 10
6. Alright so this one is asking you what the value of q would be in the equation :
0.5q = 6.25
So to find q we need to see that whatever q is will be multiplied by 0.5. And this answer will be equal to 6.25 due to the = sign. So an easy way of doing this is actually just finding what 6.25 x 2 is. Since q x 0.5 will equal to 6.25, finding 6.25 x 2 is just flipping the equation in a way.
So doing this we get 12.5 which is the very top answer of that question.
8. Alright so it looks like this question is just meant to make your brain turn into a raisin when you read it, but it isn't that hard.
Lets lay everything out :
Joe is 4 more than triple the age of luke.
x represents lukes age (x = Lukes age)
And we are finding the expression that shows joes age.
Alright so looking at the problem lets look at the key word MORE. More means addition in the math world usually so lets go off that. Lucky for you that's all you need cause you only have one addition answer here but lets still go over it why don't we.
4 + 3x
4 represents the "4 MORE than lukes age"
Then we have 3. The 3 represents the "triple the age of luke"
And finally x represents Lukes age.
So if we do 3 multiplied by x (Lukes age) we get triple lukes age :
4 + (Triple lukes age)
So now we just add the 4 and it would be in theory :
Triple Lukes age + 4 = Joes age. And that's all they want.
And then finally we have 7.
This is one fairly simple just another one meant to confused you a bit it seems.
You're basically taking the variable which is q and adding +2 to it and checking to see if the sum of that is less than 7.
So lets do that with the answers given
We will just input the number where q is in the equation and then check! :
2 + 0 < 7
2 plus 0 is 2, and is less than 7!
2 + 4 < 7
2 plus 4 is 6, and is less than 7!
2 + 5 < 7
2 plus 5 is 7. It would be correct if there was an equal sign or less than or equal to sign. But there is not so this is incorrect.
2 + 7 < 7
2 plus 7 is 9, which is greater than 7.
2 + 9 < 7
2 plus 9 is 11, which is greater than 7.
So lets look at what we plugged in that is less than (<) 7 and those are our answers! :
0 , 4
The others are either equal or greater than 7 which is not what we are looking for. So the only two correct answers here are 0, 4.
I hope this helps you! If you have any questions feel free to ask them in the comments and I will help you the best I can! :)

Answers
The solution to this equation is p = -6
This expression is related to a First Degree Equation.First degree equation is a mathematical expression and sentence, which is defined by having only one unknown. Its representation is given by: ax+b=0.
— To solve this expression, let's eliminate these square root symbols:
√-5p = √24-p
-5p = 24 - p
— Move the p term before the positive sign equality, thus also shifting the 24th term:
-5p = 24 - p
-5p + p = 24
-4p = 24
— Finally, let's divide the second to the first term of this equation:
-4p = 24
p = 24 ÷ (-4)
p = -6
Therefore, the correct result of this expression will be p = -6
If deviations are positive, then .......1. observations are above the mean 2.there is no need to perform Linear Regression 3.observations are below the mean 4.SSE will be negative
Answers
If deviations are positive, it means that the observations are above the mean. This is option 1.
Positive deviations indicate that the individual observations are greater than the mean of the dataset. Deviation is a measure of how far each observation deviates from the mean. When the deviations are positive, it implies that the observations are higher than the average or central value represented by the mean.
Linear regression is a statistical technique used to model the relationship between variables. It is not directly related to the sign of deviations. Therefore, option 2 is incorrect.
Option 3, which states that positive deviations indicate that observations are below the mean, is incorrect. Positive deviations indicate observations above the mean, not below.
Option 4, stating that SSE (Sum of Squared Errors) will be negative, is not necessarily true. SSE is a measure of the discrepancy between the observed values and the values predicted by a regression model. It is calculated by summing the squared differences between the observed and predicted values. The SSE can be positive or zero, but it cannot be negative.
In summary, when deviations are positive, it indicates that the observations are above the mean, not below. The statement that SSE will be negative is incorrect.

Consider the following normal form game: L U 0,0 D 2-3 R 2, -2 1,-1 Assume that x > 0. Moreover, assume that Player Row chooses U with probability p and Player Column chooses L with probability q. a) Derive and plot players' best response functions (p on the horizontal axis and q on the vertical axis). b) Find all the Nash equilibria (pure and mixed strategies) of the above game. Illustrate your answer in a graph (p on the horizontal axis and q on the vertical axis. Comment. Consider now the following two-player simultaneous-move game, called the rock-paper-scissors-lizard game. R stands for rock, P for paper, S for scissors, and L for lizard. R beats S but loses against P and L; P beats R but loses against S and L; S beats P and L but loses against R; L beats R and P but loses against S. The payoff for winning is 1 and that for losing is -1; when both players choose the same strategy they each get 0. Assume that Player Row chooses R with probability r, P with probability p, and S with probability $ (similarly for Player Column). c) Write down the normal form representation of the game. d) Find all the Nash equilibria (pure and mixed strategies) of the game. Comment.
Answers
(a) Player Column's best response is given by:
BR_Column(p) = { L if p < 1/2, R if p > 1/2 (indifferent if p = 1/2)
(b) Where both players are indifferent between their available strategies.
(c) The normal form representation of the game is above.
(d) No player can gain an advantage by deviating from this strategy.
This equilibrium results in an expected payoff of 0 for each player.
(a) To derive the best response functions, we need to find the strategies that maximize the payoffs for each player given the mixed strategy of the other player.
Player Row's best response function:
If Player Column chooses L with probability q, Player Row's expected payoff for choosing U is 0q + 2(1-q) = 2 - 2q.
If Player Column chooses R with probability 1-q, Player Row's expected payoff for choosing U is 0*(1-q) + 1*q = q.
Therefore, Player Row's best response is given by:
BR_Row(q) = { U if q < 1/3, D if q > 1/3 (indifferent if q = 1/3)
Player Column's best response function:
If Player Row chooses U with probability p, Player Column's expected payoff for choosing L is 0p + 2(1-p) = 2 - 2p.
If Player Row chooses D with probability 1-p, Player Column's expected payoff for choosing L is 0*(1-p) + (-1)*p = -p.
Therefore, Player Column's best response is given by:
BR_Column(p) = { L if p < 1/2, R if p > 1/2 (indifferent if p = 1/2)
Plotting the best response functions on a graph with p on the horizontal axis and q on the vertical axis will result in two line segments: BR_Row(q) is horizontal at U for q < 1/3 and horizontal at D for q > 1/3, while BR_Column(p) is vertical at L for p < 1/2 and vertical at R for p > 1/2.
The two segments intersect at the point (p, q) = (1/2, 1/3).
(b) To find the Nash equilibria, we look for the points where the best response functions intersect. In this case, the only Nash equilibrium is at (p, q) = (1/2, 1/3), where both players are indifferent between their available strategies.
Now let's move on to the rock-paper-scissors-lizard game:
(c) The normal form representation of the game can be written as follows:
R P S L
------------------------
R | 0,0 -1,1 1,-1 1,-1
P | 1,-1 0,0 -1,1 1,-1
S | -1,1 1,-1 0,0 -1,1
L | -1,1 -1,1 1,-1 0,0
(d) To find the Nash equilibria, we look for any strategy profiles where no player can unilaterally deviate to improve their payoff.
In this game, there are no pure strategy Nash equilibria since each strategy can be countered by another strategy with a higher payoff.
However, there is a mixed strategy Nash equilibrium where each player chooses their actions with equal probabilities: r = p = s = l = 1/4.
In this case, no player can gain an advantage by deviating from this strategy.
This equilibrium results in an expected payoff of 0 for each player.
In summary, the rock-paper-scissors-lizard game has a unique mixed strategy Nash equilibrium where each player randomly chooses their actions with equal probabilities.

3. A demand loan of $10,000 is repaid by payments of $5000 in one year, $6000 in four years, and a final payment in six years. Interest on the loan is at 10% per annum compounded quarterly during the first year, 8% per annum compounded semi-annually for the next three years and 7.5% per annum compounded annually for the remaining years. Determine the final payment.A demand loan of $5000.00 is repaid by payments of $2500.00 after two years, $2500.00 after four years, and a final payment after six years. Interest is 9% compounded quarterly for the first two years, 10% compounded monthly for the next two years, and 10% compounded annually thereafter. What is the size of the final payment? The final payment is 5 (Round the final answer to the nearest cent as needed. Round all intermediate values to six decimal places as needed.)
Answers
For the first loan, the final payment is $1,576.25. For the second loan, the final payment is $0. The calculations consider the given interest rates and compounding periods.
To determine the final payment for the first loan, we need to calculate the accumulated value of the loan after six years. For the first year, interest is compounded quarterly at a rate of 10% per annum. The accumulated value after one year is $10,000 * (1 + 0.10/4)^(4*1) = $10,000 * (1 + 0.025)^4 = $10,000 * 1.1038125.For the next three years, interest is compounded semi-annually at a rate of 8% per annum. The accumulated value after four years is $10,000 * (1 + 0.08/2)^(2*4) = $10,000 * (1 + 0.04)^8 = $10,000 * 1.3604877.
Finally, for the remaining two years, interest is compounded annually at a rate of 7.5% per annum. The accumulated value after six years is $10,000 * (1 + 0.075)^2 = $10,000 * 1.157625.To find the final payment, we subtract the payments made so far ($5,000 and $6,000) from the accumulated value after six years: $10,000 * 1.157625 - $5,000 - $6,000 = $1,576.25.For the second loan, we calculate the accumulated value after six years using the given interest rates and compounding periods for each period. The accumulated value after two years is $5,000 * (1 + 0.09/4)^(4*2) = $5,000 * (1 + 0.0225)^8 = $5,000 * 1.208646.
The accumulated value after four years is $5,000 * (1 + 0.10/12)^(12*2) = $5,000 * (1 + 0.0083333)^24 = $5,000 * 1.221494.Finally, the accumulated value after six years is $5,000 * (1 + 0.10)^2 = $5,000 * 1.21.To find the final payment, we subtract the payments made so far ($2,500 and $2,500) from the accumulated value after six years: $5,000 * 1.21 - $2,500 - $2,500 = $0.
