Answer:
M= -4/2 B=5
Step-by-step explanation:
First we know that when a line is slanted like this \ it is automatically negative. So then we plot 2 points on the line , make a right traingle and count the points across the x axis and then up the Y axis . X will be on the bottom(2) and Y on the top(4). Add the negative sign. Therefor M = -4/2
Now to find B we need to find the point where the line intercepts the Y axis. we see that it touches the Y axis at 5. Therefor B= 5
Well the 384 part is the harder part because it is a more complex number (for humans) so after you find out what 4x384=(1536) then 4x5000 is simple and you just add the two answers together.
Answer:
Sample mean =119.42
Median = 92
25% trimmed mean = 102.42
10% trimmed mean = 95.69
Step-by-step explanation:
Data in increasing order :
12 13 20 23 31 35 40 43 48 49 58 62 66 67 69 71 73 77 78 79 82 85 86 89 91 93 97 99 101 105 106 106 112 117 124 135 139 141 147 159 161 168 183 207 249 262 289 323 388 513
Total no. of observations = 50
Sample mean =
=
= 119.42
Median: Since we have even number of observation
Median =
=
= 92
10% Trimmed Mean: We remove 5 values from each side
Trimmed set = 35 40 43 48 49 58 62 66 67 69 71 73 77 78 79 82 85 86 89 91 93 97 99 101 105 106 106 112 117 124 135 139 141 147 159 161 168 183 207 249
Trimmed mean =
=
= 102.42
25% Trimmed Mean: We remove 12 values from each side.
Trimmed set = 66 67 69 71 73 77 78 79 82 85 86 89 91 93 97 99 101 105 106 106 112 117 124 135 139 141
Trimmed mean =
=
= 95.69
Answer:
I would probably say independent but idk
Take $65.95 times (0.0825) for the sales tax = 5.44
then, add the tax of $5.44 to the original amount of $65.95 = $75.39
