Before you sit three chests – one made of wood, one of stone, and one of steel. you know that one of the chests contains a great treasure, while the other two contain vicious, angry, man-eating, deadly poisonous scorpions (also known as scorpions). on each chest hangs a sign, giving you information about which chest contains the treasure. problem is, you do not know which signs are true and which are false. the signs read:
wood chest: if the sign on the stone chest is true, then the treasure is not in the steel chest. stone chest: exactly two of these signs are false. steel chest: the treasure is in a chest with a false sign.
which chest contains the treasure? prove your answer is correct.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

191 students play sports and ninety-seven 10th graders were surveyed.

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
