This problem has been solved! see the answera manufacturer received an order of 285 computer chips. unfortunately, 28 of the chips are defective. to test the shipment, a quality-control engineer randomly selects 17 chips from the box of 285 and tests them. the random variable x represents the number of defective chips in the sample. what is the probability of getting 4 defective chips? what is the probability of getting 3 defective chips? what is the probability that the quality-control engineer will not find any defective chips? what is the probability of finding 38 defective chips? how many defective chips would you expect to select?

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

30005

yes ok                                            

one peck is 9.309 quarts

9.309x 2

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
