Answer:
Explanation:
i took the test
The answer is 24.5 by rounding off nearest tenth it becomes 25
PROCEDURE:
1: put all the numbers in numerical order i.e.22,23,24,24,25,26,28,29;
2:now the total amount of values is even, so the median will be the mean of two central values i.e.
(24+25)/2=24.5
now by rounding it off to nearest tenth it becomes 25
Answer:
emissions = 40·0.65^t
Step-by-step explanation:
The decay factor in an exponential equation is 1+(decay rate), so the equation can be written ...
amount = (initial amount)×(decay factor)^t
where the decay factor applies to 1 unit of time t. Filling in the given values, we find ...
decay factor = 1 +(-35%) = 0.65 . . . . for 1 year
emissions = 40×0.65^t . . . . . million tons, for t in years
Enter them into a calculator (most significant digit first), pressing the "+" key between them and the "=" key after the last one.
Answer:
Step-by-step explanation:
Add 7 to both sides:
Multiply both sides by -1:
Divide both sides by 5:
