Answer:
0.9821
Step-by-step explanation:
Probability that a randomly selected value will be less than 2.1 deviations from the mean ; this means the Zscore = 2.1

Answer:
also 75°
Step-by-step explanation:
the angles across each other at a crossing point of 2 lines must be equal.
so, 2 = 3.
and the angles at the crossing point with a parallel line are simply a "mirror" or rather a copy of the angles at the crossing point with the first line.
so, 2 = 3 = 6 = 7
and 1 = 4 = 5 = 8
