Using PEMDAS, 3x 100,00= 300,000 4x10,000= 40000 8x100=800 3x10=30 add them all together 300,000+40,000+800+30+9 =======34,839
Answer:
-x/4-2/3
Step-by-step explanation:
f^-1(x)=-x/3-2/3
Answer:
0.102
Step-by-step explanation:
The number of defective modems in the inventory is 20% * 30 + 8% * 0.50 =10 (out of 80)
Note that the number of defectives in the inventory is fixed i.e. we are told that there is 1/8 probability that a modem in the inventory is defective, but rather that exactly 1/8 of all modems are defective.
The probability that exactly two modems in a random sample of five are defective is :
(10↓2)(70↓3) / (80↓5) = 0.102

We know that 5% of 100 is 5
And 5% of 200 is 10
5% of 300 is 15
So that must mean 5% of 400 is 20
