Average temperature change can be found through the equation
Avg Temp change per hour=Total temperature change ÷ Total time
=84÷12
=7
Since the temperature was decreasing, make the 7 negative -7
Hope this helps!
Answer:
c(h) = 50 +10h
c(4) = 90 . . . . . it costs $90 to rent the truck for 4 hours
Step-by-step explanation:
The problem statement tells you the total charge is the sum of $50 and a charge of $10 per hour. That is, for h hours, the total charge is ...
c = 50 + 10h
In functional form, this is ...
c(h) = 50 +10h . . . . . . total charger for a rental of h hours
__
The function value with an input of 4 is ...
c(4) = 50 +10·4
c(4) = 90
Since the input is the number of hours of rental, and the function value is the total charge, this represents the total charge for a rental of 4 hours.
<u>Answer:</u>
The correct answer option is B. equal.
<u>Step-by-step explanation:</u>
In a symmetrical distribution the mean, median, and mode are equal.
In any distribution which is symmetric, half of its curve is the mirror image of the other half. The pull remains same on each side and the frequencies are also symmetrically distributed.
Therefore, mean, median and mode all fall at the middle as one side balances the other sides.
