A lot of 100 semiconductor chips contains 20 that are defective. (a) two are selected, at random, without replacement, from the

borishaifa [10]

Given: all selections are without replacement
Let D=event that chip is defective
N=event that chip is normal
note that D and N are complementary.
x=undefined event
(a) Second is defective
Probability for second chip to be defective
P(xD)=P(ND)+P(DD)
P(ND)=(80/100)*(20/99)=1600/9900
P(DD)=(20/100)*(19/99)=380/9900
=>
P(xD)=(1600+380)/9900=1980/9900=1/5

(b) All three are defective
P(DDD)=(20/100)*(19/99)*(18/98)=19/2695

Note: in probabilities, it is preferable to use the exact values (i.e. fractions).

4−6=−2−16−2 4 k - 6 = - 2 k - 16 - 2 for

Fofino [41]

Answer:

k = -2

Step-by-step explanation:

4k - 6 = -2k - 16 - 2

Add 2 to each side

4k - 4 = -2k -16

Add 4 to each side

4k = -2k - 12

Add 2k to each side

6k = -12

Divide by 6 on both sides

k = -2 :)

Find the future value of #8000 at 12percent for 3 years

Bas_tet [7]

Answer:

Future value using simple interest = $10,880

Future value using Compound interest = $11,240 (Approx.)

Step-by-step explanation:

Given:

Principal Amount = $8,000

Rate = 12% = 0.12

Number of year = 3

Find:

Future value

Computation:

Future value using simple interest

Future value = P + (P)(R)(T)

Future value = 8,000 + (8,000)(0.12)(3)

Future value = 8,000 + 2,880

Future value using simple interest = $10,880

Future value using Compound interest

Future value = P[1+r]ⁿ

Future value = 8,000[1+0.12]³

Future value = 8,000[1.12]³

Future value using Compound interest = $11,240 (Approx.)
