Answer:

a)4/3

b)9/20 or 0.45

c)96

Step-by-step explanation:

a) j=3

72=20j+9p

72=20(3)+9p

72=60+9p

-9p=60-72

-9p=-12

p=-12/-9

p=4/3

b) m =1/2

20k-5=8m

20k-5=8(1/2)

20k-5=4

20k=4+5

20k=9

k=9/20 or 0.45

c) k=18

p+1/3k-20=82

p+1/3(18)-20=82

p+6-20=82

p=82+20-6

p=96

idk if this is right but I tried my best heh-

An electronic office product contains 5100 electronic components. Assume that the probability that each component operates witho
AURORKA [14]

Answer:

The probability that 2 or more of the original 5,100 components may fail during the useful life of the product is:

= 0.001

Step-by-step explanation:

Probability of operating without failure = 0.999

The probability of failed component = 0.001 (1 - 0.999)

The number of components of the electronic office product = 5,100

The number of components that may fail, given the above successful operation = 5.1 (0.001 * 5,100).

Therefore, the probability that 2 or more of the original 5,100 components may fail during the useful life of the product = 0.001

Probability of component failure is the likelihood that a component fails during the useful life of the product.  It is expressed as the number of likely failed components divided by the total number of components.  This result can be left in decimal form or expressed as a percentage.

(a/5) - (b/3) = (a/2) - (b/6), solve for a
Gnom [1K]

Answer:

a =  -  \frac{10}{17} b

Step-by-step explanation:

(a/5) - (b/3) = (a/2) - (b/6)

+(B/3) + (b/3)

NOTE: use property of equality to isolate <em>b</em> from <em>a</em>

(a/5) = (b/3) + (a/2) - (b/6)

-(a/2) - (a/2)

NOTE: continue to use property of equality to isolate <em>a</em><em> </em>from <em>b</em>

(a/5) - (a/2) = (b/3) - (b/6)

60((a/5) - (a/2)) = ((b/3) - (b/6))60

NOTE: 60 is a common multiple of 5, 2, 3, and 6

12a - 30a = 20b - 10b

NOTE: combine alike terms

-17a = 10b

-17a/-17 = 10b/-17

NOTE: decide by -16 to find what a is equal to

a =  -  \frac{10}{17} b

Final answer
