Fictitious Scenario Suppose you perform a hypothesis test relating to environmental
toxins in a thriving small city in West Virginia. Environmental toxins
are at a safe level if they are rated at a score of 10 or fewer. A score
above 10 indicates an unsafe toxin level - a level at which doctors
believe people will develop health problems, diseases, and early
death.
Most of the residents who live there work in coal mines and
currently this is the only place left to do this type of work in the U. S.
The workers have been doing this for generations and have few
other skills. They are happy; they raise families there and the city
used to be known as one of the best places to live and bring up
children.

3; 9 is 8 to -4

step-by-step explanation:

i honestly dont know

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .

brainliest is always apprectiated

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
