Answer:
26°
Step-by-step explanation:
x = 90° - 64° = 26°
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
Answer:
6 years
Step-by-step explanation:
let x = # of years
6 + 2x = 12 + x
x = 6
Answer:
31.9
Step-by-step explanation:
We have the hypotonouse and need the adjacent side
to solve for x we will use CAH
Cos(15)=x/33
33cos(15)=x
x=31.87555 which rounds to 31.9
