Answer:
B, C
Step-by-step explanation:
to make a triangle the sum of lengths of any and every pair of sides must be longer than the third side. otherwise the end points cannot connect.
A
3+4<8 so, it cannot be a triangle.
B
7+6>12 true
7+12>6 true
6+12>7 true
C
5+11>13 true
5+13>11 true
13+11>5 true
D
4+6<12 so, it cannot be a triangle.
E
special case
4+6 = 10
but 4+6 is not longer than 10, so, all 3 lines would "fold" into one flat line. that does not count as triangle either, although I, personally, would consider it an "extreme triangle". but the general definition does not agree with me and requires the "longer than" condition.
Median is a better measure of center than the mean(average)
a) 56,62,68,71,104,507 ⇒ Median is a better measure. Mean is not a better measure because of the outliers.
b) 2,8.5, 9.2, 9.8, 10.1 lb ⇒ Median is a better measure.
c) Mean is a better measure. No outliers. Data set values are close with each other.
d) Mean is a better measure.
Answer:
As a rule of thumb, if you know only the two shorter side, their ratio is the tangent of the angle opposed to the side you use as a numerator.
If you know one side and the hypotenuse, the ratio side/hypotenuse is either the sine of the opposite angle, or the cosine of the adjacent angle.
