A spinner with 8 equal sections is labeled 1 through 8. The spinner is spun 4 times. Three out of the 4 times, the arrow lands on 7. The predicted probability of the arrow landing on 7 is 1/8. Which statement BEST explains why the observed frequency is different from the predicted probability. * The spinner is spun more than 1 time.

The sample size is too small.
The section labeled 7 is bigger than the rest.
The predicted probability is incorrect.

If m∠abc = 70°, what is m∠abd? justify your reasoning. using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°. using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°. using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality. using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
