Answer:
Step-by-step explanation:
A number being divided by a number would be the same as a number multiplied by the reciprocal of the other number.
Reciprocal: the “flip” of a fraction (ex. the reciprocal of 6/7 is 7/6)
Example:
5/6 / 1/6
= 5/6*6/1
=30/6
=5
We can apply the same to the question 1/5 / 3.
1/5 / 3
=1/5*1/3
=1/15
I hope this helps! Please comment if you have any questions.
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:
8
Step-by-step explanation:
v = -3, w = -4,
vw + w,
Subsitute in (-3) for (v), and (-4) for (w).
(-3)(-4) + (-4)
Simplfiy,
12 + (-4)
12 - 4
8
