Amethods and measurements analyst for digital devices needs to develop a time standard for the task of assembling a computer mouse. in a preliminary study, she observed one of her workers perform this task six times with the following results: observation 1 2 3 4 5 6 time(seconds) 46 38 40 34 42 40 what is the standard time for this task if the employee worked at a 20 percent faster pace than average and an allowance of 25 percent of the workday is used? 40 seconds 50 seconds 53.3 seconds 60 seconds 64 seconds

step-by-step explanation:

in which figure is point g a centroid

oof

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours
