Answer: i will give you the first couple answers and how i got it you do the rest yourself. You need to combine like terms so add or subtract only the same numbers with the same sign. if the sign has no number imagine an invisible 1 before it. so for example the first one would be (4A) all i did was add the A together to get that i will also give you the last answer for another example. the problem is  20-9z+4y+7-x. all you gotta do is add 7 to  the 20  add -9+-x and leave the 4y alone since there is no other y the answer would be 27-10z+4y+

\\ \bull\tt\dashrightarrow \dfrac{-3}{8}x-20+2x>6

\\ \bull\tt\dashrightarrow \dfrac{-3}{8}x+2x=6+20=26

\\ \bull\tt\dashrightarrow \dfrac{-3+16}{8}x=26

\\ \bull\tt\dashrightarrow \dfrac{13}{8}x=26

\\ \bull\tt\dashrightarrow x=26\times \dfrac{8}{13}

\\ \bull\tt\dashrightarrow x=8(2)=16

A group of people were asked if they had run a red light in the last year. 315 responded "yes", and 190 responded "no".
Iteru [2.4K]

Answer:

0.624

Step-by-step explanation:

Number who have run a red light = 315

Number who haven't run a red light = 190

From the data :

The total number of people sampled = total possible outcome = (315 + 190) = 505

Selecting a person at random, probability that the selected person has run a red light :

P = required outcome / Total possible outcomes

Required outcome = Number who have run a red light = 315

P(having run a red light) = 315 / 505 = 0.624
