Answer:
x = 9
Step-by-step explanation:
60 + 6x + 16 = 13x + 13
6x - 13x = 13 - 16 - 60
- 7x = - 63
- x = - 63/7
- x = - 9
x = 9
Answer:
k=29
Step-by-step explanation:
Answer:
510 divided by 3= 170 170x4= number of students
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
