Answer:
2x-3y=2
x=6y-5
2(6y-5)-3y=2
use the distributive property.
2*6y=12y
2*-5=-10
12y-10-3y=2
combine like terms
12y-3y=9y
9y-10=2
add 10 to both sides.
9y-10+10=9y
2+10=12
9y=12
divide both sides by 9
9y/9=y
y=about 1.33
plug in the value of y in the expression equal to the value of x.
x=6(1.33)-5
solve
6*1.33=7.98
x=7.98-5
7.98-5=2.98
Step-by-step explanation:
x=2.98
y=1.33
Are rent rates influenced by the student population in a college town? Let rent be the average monthly rent paid on rental units in a college town in the United States. Let pop denote the total city population, avginc the average city income, and pctstu the student population as a percentage of the total population. One model to test for a relationship is log1rent 2 5 b0 1 b1log1pop2 1 b2log1avginc2 1 b3pctstu 1 u. (i) State the null hypothesis that size of the student body relative to the population has no ceteris paribus effect on monthly rents. State the alternative that there is an effect. (ii) What signs do you expect for b1 and b2? (iii) The equation estimated using 1990 data from RENTAL for 64 college towns is
Step-by-step explanation:
The regression equation is correctly written as:
log(rent) = β₀+β₁log(pop)+β₂log(avginc)+β₃pctstu+μ
1. this question requires us to State the null hypothesis that size of the student body relative to the population has no ceteris paribus effect on monthly rents.
null hypothesis
H₀ : β₃ = 0 (no effect exists)
alternative that there is an effect.
H₁ : β ≠ 0
2.
Due to increased demand when population is increased, the higher the number of people living in the city then there is a great likelihood that rent would increase. β1 will therefore be positive, all things being equal.
as average income rises, so also would rent as the people would have more money and therefore there would be increased demand for housing. This increase in demand would then cause a surge in the price of rent. β₂ would therefore be positive .
the last question you posted is incomplete so i was unable to go ahead with it.
please assist me with these problems
Answer: see below
Step-by-step explanation:
Speed = | Velocity |
4.
Velocity -14 20 -2 0 25 -15
Speed 14 20 2 0 25 15
5.
Velocity -16 16
Speed 16 16
6.
3 is greater then -4
|---------|---------|
-4 0 3
7.
A velocity of -4 has a greater speed than a velocity of 3
Velocity -4 3
Speed 4 3

A landlord is considering upgrades and repairs, including wood floors, kitchen tile, a new back door, and a repaired garage door. The landlord could do these things himself or hire a contractor. The contractor could finish the job in half the time but would charge more. The landlord wants to leave the choice of whether to actually upgrade the kitchen tile up to the optimization algorithm. How should this constraint be written if he uses the following scheme for decision variables? x1 = contractor works on wood floors x2 = landlord works on wood floors x3 = contractor works on kitchen tile x4 = landlord works on kitchen tile x5 = contractor works on back door x6 = landlord works on back door x7 = contractor works on garage door x8 = landlord works on garage door Group of answer choices x3+ x4≤ 1 x3+ x4= 1 x3- x4= 1 x3- x4≤ 1
Answer:
x3 + x4 ≤ 1
Step-by-step explanation:
Upgrades considered = wood floors, Kitchen tile, New back door and a repaired garage
The constraint of whether to upgrade the kitchen either by the landlord or by a contractor can be represented with the scheme below:
x3 + x4 ≤ 1
The constraint is written this way because only one scheme can be used at a time i.e when x3 = 1 , x4 = 0 and vice versa. also
note that both x3 and x4 can be = 0. because the upgrade of the kitchen tiles is under probability and the landlord might decide not to upgrade the kitchen tiles hence both schemes ( x3 and x4 ) can be = 0

Answer:
The answer is 1.5, 9
Step-by-step explanation:
If you can see the graph the speed increases
The ordered pair on the line (1.5, 9). The correct answer would be an option (D).
What is an ordered pair?An ordered pair is made up of two components isolated by a comma and put inside parentheses. (x, y) indicates an ordered pair, where 'x' is the first component and 'y' is the second component in the ordered pair.
The graph below represents the distance Manuel walks over several hours.
The first and second options are not accurate since the distance is measured in miles up to 10 miles, hence the options can't be correct
The correct answer is option D since the value at t = 1.5 is equal to 9 miles
Thus, the ordered pair is on the line (1.5, 9).
Hence, the correct answer is an option (D)

time the player hits a cone. What integer represents
the change in total points if the player hits 10 cones?
Answer:
-60
It is -60 because if it takes away 6 points for each cone you hit and you hit 10, then it would be -60 times 10, which equals -60.
