Answer: Probability that a randomly selected unit will contain at least two surface- finish defect is 0.04.
Step-by-step explanation:
Since we have given that
Mean rate defects per unit = 0.3
Since we will use "Poisson distribution":

But we need to find the probability that a randomly selected unit will contain at least two surface-finish defect.

So,

so, it becomes,

Hence, probability that a randomly selected unit will contain at least two surface- finish defect is 0.04.
Multiply 198 by 3 or 4 and find he closest one
Answer: x=-7
Step-by-step explanation:
1) The angles of a triangle are equal to 180
2) Add your angles together and set them equal to 180 like this:
x+59+x+51+84=180
3) Combine like terms:
2x+ 194 =180
4) Subtract 195 from both sides:
2x+ 194 =180
- 194 -194
2x = -14
5) Divide by 2 on both sides
2x= -14
/2 /2
x= -7

Answer:
14.4
Step-by-step explanation:
You know they have 12 apples, and they use 5/6 of them to bake a pie. So in that case you divide. and there you got your answer.
