The value of B1 shows a fall in demand as price rises by a unit. The point prediction is given as y = 306,560.8
<h3>How to solve the question using the intercept</h3>
The regression equation shows that y= 306,619-27.71.x
b1 = -27.71
The interpretation for b1 is that if the price of this good is increased by 1, then the demand for the good would fall by about 27.71.
<h3>The point prediction for demand</h3>
The regression line equation is given as
y= 306,619-27.71.x
when x which is price is = 2.10
Then the value of y would be:
y = 306,619 - 27.71*2.10
y = 306,560.8
c. a 95% C1 for B1 is given as:
1.96 * 27.71.
= 54.31

What you should do first is simplify the equation into the y = mx + b format. Move 2x to the other side. Know that in doing this, 2x must become the opposite of what it currently is (-2) in order for the equation to remain true. We also have to take away the '10' because the line is parallel, not exactly the same, which means a different y intercept. This looks like:

Next, simplify y to make things easier. This can be done by dividing both sides by 5, like so:

What you should also know is that if a line is parallel to another, then this means the slope has to be the same because they both have the same changes in rise and run. With this in mind, simply plug in the x and y values.



Add 2 to both sides to isolate b.

Which means that -2 = b.
Now that we have the y intercept, we can write the equation of the line, which is
.

Answer:
see below
Step-by-step explanation:
The circumference is given by
C = pi *d
C = 15.5 pi
If we approximate pi by 3.14
C = 15.5 * 3.14
C =48.67
If we use the pi button
C =48.69486813
Answer:
88 I think
Step-by-step explanation:
Well 3/5 of 220 is 132, so 132 of the students are girls and 88 of the students are boys because 220 - 132 = 88.
