Wong constructs the following arqurnent: Angle a is [missing reason 1] and therefore congruent to one angle in the triangle formed by lines m, x, and y.
Angles b and care [missing reason 2] and therefore congruent to two other angles in the triangle.
The sum of the three angles in a triangle is 180 degrees. Therefore m Za tm Zb+m lc= 18o.
What are the missing reasons in Wong's argument?
Reason 1: an alternating exterlor angle with one angle In the triangle
Reason 2: vertical angles with the other two angles In the trlangle
O
Reason 1: an alternating exterlor angle with one angle In the trlangle
Reason 2: complementary angles with the other two angles in the triangle
O

Which of the following are parts of a sphere

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
