Answer:The mean is most likely exactly 27.5 pounds, is true about the given statement The median weight of a checked bag is 27.5 pounds.
Explanation:
Median weight of a checked bag is= 27.5 pounds
it means , if there are n bags , the middlemost bag has weight 27. 5 pounds.
For , a data set, if it is symmetrical on both sides that is if difference between two succeeding values are same,then
Median = Mean
Otherwise , in some cases
Either, Median > Mean or Mean > Median.
Supposing each bag to be Equivalent, that is if they have equal weight,
Mean can't exceed ≥ 27.5 Pounds
A) You want to find t such that
.. C(t) = d
.. d = 20 +60*0.95^t
.. (d -20)/60 = 0.95^t
.. log((d -20)/60) = t*log(0.95)
.. t = log((d -20)/60)/log(0.95) . . . . . . time to cool to d degrees (d > 20)
b) C'(t) = 60*0.95^t*ln(0.95)
.. C'(1) = 60*0.95*ln(0.95) ≈ -2.924 °C/min
I’m pretty sure that the answer is D
The answer is 5 13/15 or atleast according to calculator.net (the website used in the picture) :)
