Answer:
The 10% trimmed mean is the mean computed by excluding the 10% largest and 10% smallest values from the sample and taking the arithmetic mean of the remaining 80% of the sample (other trimmed means are possible: 5%, 20%,, etc.) Example Consider the data (sample)
Answer:
a+B=c. x+8=17. x+8-8=17-8.
x=9
Answer: 135, 45, and 135 are the three other angles
==================================================
Explanation:
For a parallelogram, we'll have opposite angles with the same measure. So if one angle is 45 degrees, then the opposite angle is also 45 degrees. The other two angles are 180-45 = 135 degrees each. Adjacent angles in a parallelogram add to 180 degrees.
Answer:
Step-by-step explanation:
The direction of movement of Jordan on his birthday forms a right angle triangle. His movement from his house to his parents due south represents the opposite side of the right angle triangle. His movement due west represents the adjacent side and the movement back home along the straight line, d represents the hypotenuse. To determine d, we would apply the Pythagorean theorem. Thus
d² = 6² + 4² = 52
d = √52 = 7.2 km
The total distance that he drove on his birthday is
6 + 4 + 7.2 = 17.2 km
20% of the regular price was off.
So 80% of the regular price stayed on.
$33.96 was that 80% of the regular price.
(0.8) · (regular price) = $33.96
Divide both sides by (0.8).
Regular price = ($33.96) / (0.8)
<em>Regular price = $42.45</em>
