The makers of Laundry Whizz considered a new promotional method for their product. A small bottle of Laundry Whizz was placed in the mailbox of college students as they came on campus in the fall. Along with the Laundry Whizz, the students received a coupon for $1.00 off their next purchase. They could receive another coupon for $3.00 off if they went online and emailed five friends at another college, telling them about Laundry Whizz. The friends could then go to a website and print a coupon for $2.00 off their next purchase. The sample bottles given to the college students are an example of , while the emails to the five friends are an example of .

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

is there supposed to be a diagram or a graph for this one? ?

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
