Answer:

x = 3

Step-by-step explanation:

use distribution to multiply everything in the parenthesis by -5.

(-5x - 40) = -55

add 40 to both sides to isolate the variable which in this case is x

-5x = -15

simplify

x = 3

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

I need some help with this question :/

You have one of the answers correct. The fraction 4/8 is equal to 1/2

Other answers are: 5/10, 10/20, and 6/12

If you reduced each of those fractions, you'd get to 1/2. 

You can use a calculator to find that
4/8 = 0.5
1/2 = 0.5
5/10 = 0.5
10/20 = 0.5
6/12 = 0.5
All fractions mentioned lead to the same decimal value, so this confirms all of the fractions are equivalent to one another.

What is the answer to:
velikii [3]
Weird way to write it but alright! (Sideways) 

19pq^-2 x 5pq^6 = ?

These problems are pretty much single operations between each of the variables / constants. 

So it's like this: 

(19*5)(p*p)(q^-2*q^6) = ?

19*5 is 95.

For p*p remember that when two variables multiply there given powers add. In the case where the powers are not shown (like in the case of p*p) they are always assumed to be 1. So what is 1+1? 2. 

p*p is p^2

For q^-2*q^6 it is the same deal with the previous problem. So now the problem looks like this: 

-2 + 6 = 4 
(The two is negative, because the power is negative 2) 

So, q^4. 

Our final answer is all of the combined.... like a so: 

95p^2q^4
