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:
z=6
Step-by-step explanation:
z/3 + 1/2 = 5/2
Subtract 1/2 from each side
z/3 + 1/2-1/2 = 5/2-1/2
z/3 = 4/2
z/3 =2
Multiply each side by 3
z/3*3 = 2*3
z = 6
The biggest is hm that is because it matters
Answer:
One helpful technique I used to stay focused is to buy a pack of m&ms or mini candies and every time I complete a problem I eat one candy or m&m. Also, try making a goal for yourself for example "my goal is to complete 100 problems in an hour"
