Answer:
50
Step-by-step explanation:
6m-n
Let m = 9 and n = 4
6*9-4
Multiply first
54-4
Then subtract
50
Answer:
1,000
Step-by-step explanation:
all you have to do is y/x
3,000/3=1,000
14. < 3,< 6,< 7
15. < 3,< 7,< 5
16. Are there numbers marked?
17. < 1 , < 4 , < 5 = 110
< 7 , < 6 , < 3 ,< 8 = 70
Add MN and NR together.
25 + 12 = 37. Make sure to add the word units on the end if it’s not multiple choice.
Mean for each hour = 1
Mean for four hours, m = 4
P(x,m)=m^x*e^(-m)/x!
where x is number of defects.
P(X<=3,4)
=P(X=0,4)+P(X=1,4)+P(X=2,4)+P(X=3,4)
=0.01832+0.07326+0.14653+0.19537
=0.43355
Probability of at most 3 defects in four hours is 0.43355
