Answer:

13km

Step-by-step explanation:

We can use the formula [ r = C/2π ] to solve.

r = 81.64/2(3.14)

r = 81.64/6.28

r = 13km

A lot of 100 semiconductor chips contains 15 that are defective. three chips are selected at random from the lot without replace

Alex787 [66]

D=event that chip selected is defective
d=event that chip selected is NOT defective

Four possible scenarios for the first two selections:
P(DDD)=15/100*14/99*13/98=13/4620
P(DdD)=15/100*85/99*14/98=17/924
P(dDD)=85/100*15/99*14/99=17/924
P(ddD)=85/100*84/99*15/98=17/154

Probability of third selection being defective is the sum of all cases,
P(XXD)=P(DDD)+P(DdD)+P(dDD)+P(ddD)
=3/20

Which equation is equivalent to − ( 6 − x ) = 24 ?

kondor19780726 [428]

(6-x)=24

X=-18

If you subtract a negative number with a positive number it adds them together making it positive (6- -18)=24
