A company manufactures a new type of LED light bulb. The lifespans of these light bulbs, in hours, are a continuous random variable with probability density function f(x)=0.0008−0.00000032(x−14000) from 14,000 to 16,500 hours. Use Excel to find the probability that a randomly selected LED light bulb will have a life span between 15,500 and 15,800 hours. Use an interval width of 10.

12*c

step-by-step explanation:

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

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

step-by-step explanation:

infinity is the answer
