In math, "is" means "is equal to"
"of" means "times"
Multiply each side by 10: 0.4 = 'x'
(a) True
Because the sum of the angles in a triangle is 180°
Obtuse angle = angle greater than 90°.
180° - Obtuse angle = less than 90°
So there cannot be another obtuse angles, therefore both the other angles will be acute.
Y= mx+b is the formula for writing and equation for slope.
M= slope
B= y-intercept
You replace the m and b with the info given to you in the problem.
Answer: y = -3/4x -6
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
