31% adults favor the use of unmanned drones by police agencies. twelve u. s. adults are randomly selected. find the probability that the number of u. s. adults who favor the use of unmanned drones by police agencies is

(a) exactly three,
(b) at least four,
(c) less than eight.

a) 0.23

b)0.54

c)0.9856

Step-by-step explanation:

I have attached the steps

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.

step-by-step explanation:

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
