Answer:
D. Mean absolute deviation
Step-by-step explanation:
Median gives us : 159
Range gives us: 680 - 127 = 553
mean gives us :
127+137+159+188+680 = 1291
1291 / 5
= 258.2
MAD gives us the mean deviation (avg change from the mean):
mean
= 258.2
258.2 - 127 =131.2
258.2 - 137 =121.2
258.2 - 159 =99.2
258.2 - 188 =70.2
680 - 258.2
=421.8
Find the mean of the variances:
70.2+99.2+121.2+131.2+421.8 = 843.6
843.6 / 5
= 168.72
Mad = 258.2 +- 168.72
Obtuse scalene, because none of the side are equal ( which would make none of the angles equal), but the one angle is over 90°
Answer:
The tax amount is 15.17$
The tax rate is 12.4%.
Step-by-step explanation:
First we subtract the cost from the selling price.
137.17 - 122 = 15.17
We have found the tax amount, now for the tax rate.
If tax rate is x, then
122 * x = 137.17
Divide both sides by 122 to get
x = 137.17/122 = 1.124, or .124.
Then convert into percentage by moving the decimal to the right 2 times.
.124 = 12.4%
Hope this helps you
Is that just the question? I can help you out but it doesn’t make any sense.
