12. on saturday, querida gave away 416 coupons for a free appetizer at a
local restaurant. the next day, she gave away about 52 coupons an hour.
a. is the number of coupons querida gave away on sunday proportional to
the number of hours she worked that day?

b. is the total number of coupons querida gave away on saturday and
sunday proportional to the number of hours she worked on sunday?

a. YES

b. NO

Step-by-step explanation:

On Saturday,

Querida gave away 416 coupons

on Sunday

she gave away about 52 coupons an hour.

a. Is the number of coupons Querida gave away on Sunday proportional to

the number of hours she worked that day?

YES

because, judging with saturday and sunday data, it can be deduced that

52 coupon = 1hour

416 coupon = 8hours = 1day

b. Is the total number of coupons Querida gave away on Saturday and

Sunday proportional to the number of hours she worked on Sunday?

NO

the total number of coupons Querida gave away on Saturday and

Sunday is proportional to twice the number of hours she worked on Sunday.

coupons (sat + sund) = 2* hours worked on Sunday

i would need to see the dot plot : )

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
