Answer:−
-12/31
Step-by-step explanation:
The z-score for 36,000 is (36,000 - 40,000) / (15,000 / √25) = -1.333
The z-score for 42,000 is (42,000 - 40,000) / (15,000 / √25) = 0.6667
P(36,000 < x < 42,000) = P(-1.3333 < z < 0.6667)
P(z < 0.6667) - P(z < -1.3333)
0.7475 - 0.0913
0.6562
Click off the first one because 180 (Thea) < 225 (Eleanor). Then keep the second one and click the third and fourth one.
Answer:
y=18 when x=6 k = 3

there,making k the subject of the formulae
k=y/x
k=18/6
k=3
