Answer: Option B (2x=28°, x=14°)
Step-by-step explanation: 2x+44° = 72°
<u><em>Let the point of intersection be O</em></u>
∠O = 180° - (28°+44°)
180°-72° = 108°
∴ As we know that 2x+44=72°
2x= 72-44
2x=28°
∴x=28/2 = 14°
Therefore the correct answer is Option B (2x=28°, x=14°)
Answer:
A) According to the regression equation, regardless of whether or not smoking is allowed in bars, the number of cigarette packs sold per 1000 people decreases by approximately 1424 for each additional dollar of cigarette tax.
Step-by-step explanation:
Given the regression equation:
PACKS i= 57221.431732 − 1423.696906TAXi + 155.441784BARSi + eᵢ.
BARS i= 1 if city i allows smoking in bars
BARSi = 0 if city i does not allow smoking in bars
R2 = 0.351292
P-value = 0.086529
Conlusion:
Simnce p value, 0.0865 is greater than level of significance, 0.05, BARS is not significant. Thus, allowing smoking in bars increase cigarette sales, since the coefficient of BARS is positive.
Correct answer is option A.
According to the regression equation, regardless of whether or not smoking is allowed in bars, the number of cigarette packs sold per 1000 people decreases by approximately 1424 for each additional dollar of cigarette tax.
