Aproton represents a positive charge. write an integer to represent 5 protons. an electron represents a negative charge. write an integer to represent 3 electrons.

Answer

Given,

proton represent positive charge                                    

the integer that will give the  representation of 5 protons will be equal to + 5

an electron represents negative charge                                            

the integer that will give the representation of 3 electrons will be equal to -3

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
