A researcher found the average cost of one and two-bedroom apartments for different cities and graphed the data in a scatter plo

t, with costs of one-bedroom apartments along the x-axis. The variables have a strong linear correlation and the equation for the regression line is yˆ=1.377x+137.763 .
Based on the equation, what should the researcher expect for the average cost of a two-bedroom apartment in a city where the average cost of a one-bedroom apartment is $724?


about $1272


about $1135


about $1083


about $1062

The average cost of a two-bedroom apartment in the city will be about $1135

Step-by-step explanation:

The regression line equation is yˆ=1.377x+137.763 where x is the cost of one-bedroom apartment.

Given that the average cost of one-bedroom apartment is $724, then using this value for x

yˆ=1.377*724+137.763  = 1134.711

This value is approximately $ 1135

How do I solve this question?
Tanya [424]
Before attempting to solve this question, we must first know three things.

1. A straight line has a measure of 180 degrees.

2. When two angles add up to 180 degrees, those angles are called supplementary.

3. The interior angles of a triangle add up to 180 degrees.

We can see ∠ECT = 180 degrees.

∠DCT is supplementary to ∠DCE.

∠DCT = 140 degreees
∠DCE = x degrees

x + 140 = 180

Solve for x.

x + 140 = 180
x = 40 <-- Subtract 140 from each side

∠DCE = 40 degrees

We know the two interior angles of ΔDEC.

45 + 40 + x = 180

Solve for x.

45 + 40 + x = 180
85 + x = 180 <-- Combine like terms
x = 95

So, the missing angle is equal to 95 degrees.

What is the value of x ?
4vir4ik [10]

Answer:

What is the value of x?

Whenever we have a problem to solve we assume the unknown quantity(or value to be identified) as x. This is just a convention followed in algebra by using a variable to denote the unknown quantity and then arrive at the solution.

What is the value of X?

What's the value of X?

X + X = X, what is the value of X?

What is the value of x ? How can I find it?

Do you know the value of x?

Value of X can be any numerical value or anything but depends solely on your question .But I find no question ok lets take an example .

If an equation is given ,

X+2=4

=> X=4–2

=>X=2

We X's value as 2 .

Now another ,

X + Y = 5 , 2X + 5Y = 10

Now taking first equation

X = 5-Y ………………………..(1)

Now taking second equation

X= 10–5Y/2…………………(2)

Now,

2(5-Y) = 10–5Y

=> 10–2Y = 10–5Y

=> 2Y = 5Y

Y has no value here because this equation not correctly represented .

Hence ,

We conclude the value of X varies with equation .

Thank You ,
