The bar graph below displays students’ responses to the question "What caffeinated drinks do you consume?” A bar graph titled Caffeinated Drinks has drink on the x-axis and relative frequency on the y-axis. Coffee, 0.8; tea, 0.7; soda, 0.7; energy, 0.2.

Would it be appropriate to display the data with a pie chart?

Yes, because the data are grouped into categories.
Yes, because the data can be represented by a relative frequency compared to the whole.
No, because the data add up to more than 100%.
No, because the data categories are too broad.

Yes, because the data are grouped into categories.

Step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

you would need to also lose 1 point for each of the other outcomes for it to be fair.
