Both A) and C) are correct.
Moving to the left is more negative (x) and moving up is more positive (y). Hence x translating -4 --> -6 is 2 units left [A], and y translating 2 --> 4 is 2 units up [C].

I need help with this problem what fractions are equivalent to 4.05 repeating
kow [346]

Answer:

401/99 and 802/198

Step-by-step explanation:

Unfortunately the other answer to this question is wrong - you are looking for something equivalent to 4.0505050505050505, not just 4.05.

Typing the answer suggestions into a calculator you get:

405/99 = 4.0909090909 which is incorrect

401/99 = 4.0505050505 which is correct

81/33 = 2.45454545455 which is incorrect

802/198 = 4.0505050505 which is correct

405/100 = 4.05 which is incorrect as it doesn't repeat.

Hopefully this helps, let me know if you have any questions :)

Why do plasma particles have charges?​
r-ruslan [8.4K]

Answer:

"Because the particles (electrons and ions) in a plasma have an electrical charge, the motions and behaviors of plasmas are affected by electrical and magnetic fields. ... Ions have a positive electrical charge because they have more positively charged protons than negatively charged electrons."

A survey about phone service has a margin of error of 5%. Out of 150 people surveyed, 103 said that they were pleased with their
lapo4ka [179]

Answer:

The range of the number of people that are satisfied is option A. 46,968 to 51,912 customers.

Step-by-step explanation:

Hi, to solve this problem you need to calculate the total number of customers that are pleased with the service, based on the 150 people sample.

so:

(72,000 x 103 )÷150 = 49,440

The next step is to calculate the 5% margin of error of that result.

49,440 x 0.05= 2,472

Finally, to obtain the range you need to add and subtract the margin to the total number of customers that are pleased with the service.

49,440-2,472= 46,968

49,440 + 2,472=51,912

So, the range of the number of people that are satisfied is option A. 46,968 to 51,912 customers.
