13 + 15 + 18 +14 = 60 total hats
15 are white
60-15 = 45 hats that are not white
45/60 reduces to 3/4
3/4 =0.75 probability the hat will not be white
Answer: Fatigue level
Step-by-step explanation: Dependent variable refers to the measured or observed variable in an experimental study. The dependent variable is the variable observed or studied in other to make assessment of effects which occurs by varying the independent variable. In the study described above, the self reported fatigue level is measured or recorded while subjecting the participant to varying conditions of noise; white noise and normal noise level, which are the independent variables. The dependent variable, fatigue level is the variable being measured in the experiment by subjecting the participants to the two different traet ment conditions which are the independent variables.
To find the mean just add all the numbers together then divide them by how many numbers there are.
To find the median you have to rewrite the list in numerical order then pick out the middle one which will be your answer
The mode is the number that is repeated more often than the others
For range pick out the largest and smallest number in the group and subtract those, the value you get will be the range :) Hope this helped

Answer:
<em>The final price including tax is $41.89</em>
Step-by-step explanation:
The following items are on sale:
Sleeved dress $17.99
Skirt $16.19
T-shirt $8.99
Subtotal $43.17
The cheapest item is the T-shirt for $8.99 and it will be discounted by 30%:
$8.99 - 30/100 * $8.99 = $8.99 - $2.70 = $6.29
The total sale price is now: $43.17-$2.70=$40.47
Now we add the 3.5% tax:
$40.47 + 3.5/100 * $40.47 = $40.47 + $1.42 = $41.89
The final price including tax is $41.89
