Atwo-way frequency table shows baldness in men over 45 and men under 45:
under 4 over 45 total
bald 24 16 40
not bald 36 24 60
total 60 40 100
based on this data, are baldness and being over 45 independent events?
no, p(bald ∩ over 45) ≠ p(bald) ⋅ p(over 45)
no, p(bald ∩ over 45) = p(bald) ⋅ p(over 45)
yes, p(bald ∩ over 45) ≠ p(bald) ⋅ p(over 45)
yes, p(bald ∩ over 45) = p(bald) ⋅ p(over 45)
it's not a.

‼️‼️‼️‼️‼️the pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas. if the pressure is 6 pounds per square inch when the temperature is 440 f, find the pressure exerted when the temperature of the gas is 380°f. (show work)
