Answer:
0.0016283
Step-by-step explanation:
Given that:
Proportion of defective bulbs, p = 30% = 0.3
Sample size, n = 19 bulbs
Probability that the lot will pass inspection :
P(none of the 19 is defective) Or P(only one of the 19 is defective)
P(none of the 19 is defective) = (1 - p) ^n = (1 - 0.3)^19 ; 0.7^19
0.7^19 = 0.0011398
P(only one of the 19 is defective) :
P(1 defective) * P(18 not defective )
(0.3) * (1 - 0.3)^18
0.3 * 0.7^18
0.3 * 0.001628413597910449 = 0.0004885
Hence,
P(none of the 19 is defective) + P(only one of the 19 is defective)
0.0011398 + 0.0004885) = 0.0016283
Answer:
1x
Step-by-step explanation:
Area is length times width. Because there isnt a value for x, the area is just 1x. Let me know in the comments if it was right!
Malia : y = 8.1x.....this tells me she makes 8.10 per hr worked
Bill : if he earned 144.90 for working 18 hrs.....144.90/18 = 8.05 per hr worked.
so Malia makes 5 cents more per hr worked.
Is that the answer ur looking for ?
Answer:
