Step-by-step explanation:
Answer:
2 step equation problems.
Step-by-step explanation:
So you need to replace -3 into that to add -18 on both sides and that gives you the negative number is -20 and then you add the -5r+-3r less than or equal to -20. Now, negative -5 +3 = -8 + -20 = -28. r=-28.
8,000,000 + 200,000 + 5,000
This should be the answer and I showed you how to do it
(X,Y), ( 2,-8)
Answer:
2
Step-by-step explanation:
Given that:
Flawed bulbs = 4
Not flawed = 26
Total examined = (flawed + not flawed)
Total examined = (4 + 26) = 30
P(flawed) = flawed / total
P(flawed) = 4 / 30 = 0.1333333
If 15 is examined :
Expected number of flawed bulbs :
(4/30) * 15 = 2
