Part a): the first one Part b): 6688 (I think)
Step-by-step explanation:
15200/50= 304
304*22= 6688
The complete question is;
Marquis wrote the linear regression equation y = 1.245x - 3.685 to predict the cost, y, of x songs purchased. Marquis spent $40 on songs. Which is the best estimate of the number of songs that Marquis purchased?
Answer:
The best estimate of the number of songs that Marquis purchased = 35 songs
Step-by-step explanation:
First of all, let's make x the subject of the linear regression equation.
We are given that,
y = 1.245x - 3.685
So,
1.245x = (y + 3.685)
x = (y + 3,685) / (1,245)
We are told that Marquis spent $40 on songs.
Thus;
Substituting the value of $40 for y into the equation to get;
x = (40 +3,685)/(1,245)
x = 35.09
x ≈ 35
Thus, the best estimate of the number of songs that Marquis purchased is 35
Answer:
(-16x + 13)° + (-20x + 23)° = 180° ( St. angle)
-16x° + 13° - 20x° + 23° = 180°
-4x° + 36° = 180°
-4x° = 180°-36°
-4x° = 144°
-x° = 144°/4
-x° = -36°
x° = 36°
