Answer:

Step-by-step explanation:
<u><em>the mean in period</em></u> 1 :
(2.3+2.1+2.2+2.2+2.2+2.1+2.4+2.5+2.2+2.0+1.9+1.9+2.1+2.2+2.3)÷15=21.733...
<u><em>the mean in period</em></u> 2 :
(2.3+2.1+3.3+1.5+3.6+1.6+3.0+1.1+4.7+2.1+2.4+1.9+2.8+0.5+2.3)÷15=23.466...
Since 23.466 > 21.733 then “The mean in period 2 is higher than the mean in period 1”.
Answer:
Both ways are correct
If you multiply the cost by 8% and add, you will still get 108% as your total.
Answer:
B = log₃243 = 5
Step-by-step explanation:
By using the rule of aⁿ = b ==> logₐb = n, you can transform the exponent form into a logarithmic form by switching around the values of each letter to their desired place. It is interchangable between the two equations.
If you do 3 houses in one day then that would be 8 hours and 25 minutes.
