A = πr²

3.14*20² = 1256

52/2 = 26

3.14*26² = 2122.64

A farmer owns chickens and sheep. One day, he observed that when his animals were all together, there were at least 30 legs but
motikmotik

Answer:

c+s < 12, 2c+4s >= 30.

Step-by-step explanation:

Known: at least 30 legs, less than 12 heads.

Each animal has one head, so if there are less than 12 heads, then c + s < 12.

Sheep have four legs and chickens have two legs, so if there are at least 30 legs, then # of chicken legs + # of sheep legs >= 30, ----> c(2) + s(4) >= 30, ----> 2c + 4s >= 30.

The graph attached models the problem is you set the x axis as "c" (# of chickens) and y axis as "s" (# of sheep).

A quality control inspector has drawn a sample of 19 light bulbs from a recent production lot. If the number of defective bulbs
Inessa05 [86]

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
