The correct choice is A) between 645.2 and 724.8.
According to the empirical rule, 68% of data will fall within 1 standard deviation from the mean. This means it will be either 39.8 lower than the mean or 39.8 higher than the mean:
685-39.8 = 645.2
685+39.8 = 724.8

Heyy, Edge user here!
Step-by-step explanation:
Your answers are most definitely the third and fifth one. I don't know if there are more answers, cause if there are, please show them. I'd say your last answer is second one, but I am not totally sure. Again, please tell if there are more answers!

Answer:
$19.15
Step-by-step explanation:
Equation 1: 8.50+4.25+4.25= 17.00 (price of the popcorn and drinks)
Equation 2: 17.00/7.89= 2.15 (how to find how much the tax is)
Solve: 17.00+2.15=19.15 (add the tax to how much the popcorn and drinks were)
IF you are solving for d:
isolate the D, do the opposite of PEMDAS.
-d/6 + 12 = -7
(subtract 12 from both sides)
-d/6 + 12 (-12) = -7 (-12)
-d/6 = -19
(multiply 6 to both sides)
-d/6(6) = -19(6)
-d = -19(6)
-d = -144
-d/-1 = -144/-1
d = 144
hope this helps
