More than a hundred million e-mails are sent around the world each day, and they are all vulnerable to interception. Digital technology has aided communication, but it has also given rise to the possibility of those communications being monitored. Which type of evidence is used in the excerpt?

Statistical evidence

Explanation:

Statistical evidence is a proof based on tests and experimental data collected through the use of adequate researches carried out that is used to convince others. These evidence are usually in mathematical form. Statistical evidence are used to make facts to be clearer and provide an understanding of the data collected thereby increasing the chances that these facts would be believed.

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4
