Answer: Our required probability is 0.11.
Step-by-step explanation:
Since we have given that
Number of workers in first shift = 21
Number of workers in second shift = 15
Number of workers in third shift = 13
We need to find the probability of choosing exactly two second shift workers and two third shift workers.
So, it becomes,
Hence, our required probability is 0.11.

Answer:
<em>X Intercept:</em> (6,0)
<em>Y Intercept:</em> (0,2)
Step-by-step explanation:
Plug y = 0 into the equation and solve the resulting equation −3x = −18 for x. Plug x = 0 into the equation and solve the resulting equation −9y = −18 for y.
Answer:
2.5 seconds since the first ball was hit.
Step-by-step explanation:
The equations that model the heights are:
When the balls meet, both heights are equal, therefore:
-16t² + 56t = -16t² + 156t - 248
-16t² + 56t + 16t² - 156t + 248 = 0
- 100t + 248 = 0
248 = 100t
248/100 = t
t = 2.48 ≈ 2.5
