Abatchof140semiconductorchipsisinspected by choosing a sample of 5 chips without replacement. Assume 10 of the chips do not conf
Mkey [24]

Answer:

Step-by-step explanation:

given that a batch of 140 semiconductor chips is inspected by choosing a sample of 5 chips without replacement.

10 chips do not conform to customer requirements.

i.e. out of 140 chips 10 are defective and 130 are good

a) 5 chips can be selected form 140 chips in 140C5 ways

= 416965528

b) For containing exactly one non conforming chip we have one selected from 10 and other 4 selected from 130

No of ways = 10C1 (130C4)\\=10(11358880)\\=113588800

c) For atleast one nonconforming chip we can calculate as total - no non conforming

i.e. 416965528-130C5\\= 416965528-286243776\\=130721752

Chinedu sat down to do his homework, which included 30 math problems. He solved 2 problems each minute. Let f(n) be the number o
vova2212 [387]

Answer:

It would be an arithmetic sequence.

Step-by-step explanation:

This is because during each minute, he does another 2 problems. Or, in other words +2 each minute.

This is the result of the sequence during each minute:

(Problems Left): <em>30, 28, 26, 24, 22... 0</em>

Time (Minutes) --->

If it was instead a geometric equation, it would go by a multiple, such as the number 2. Or, ×2 each minute.

During the first minute, he learns 2 problems. But then as each minutes passes it turns into 4, then 8, and etc..

This is the result of the pretend sequence during each minute:       (Problems Left): <em>30, 28, 24, 16, 0</em>

Time (Minutes) --->

The formula would be for this equation would follow

an = a1 + (n-1)d

an is your result.

a1 is the first number you plug in

(n-1) is just there, don't mind it (aka: the term position).

and d is the rate.

So just plug them in from your equation, and you would get this:

an = 30(n-1)2
