5+(-7)+3+(-6)=-5
Answer is zero
Answer:
A
Step-by-step explanation:
This is a strict inequality so the line must be dotted, meaning it can only be A or D.
The inequality says that y is less than -2x+4 so we want the region under the line, making A the correct answer.
Using a 1-sample z-interval for the population proportion with confidence level 0.997, the sample probability is 0.69 with margin of error of 0.16, so between 0.69+0.16=0.85 of the population and 0.69-0.16=0.53 of the population prefers coffee. 84% and 54% are the correct answers.
