Answer:
Step-by-step explanation:
From the set of 100 with 10 defective microprocessors, the probability of picking a defective one is;
10/100 = 1/10
From the set of 99 remaining and 9 defective microprocessors, the probability of picking a defective one is;
9/99 = 1/11
From the set of 98 remaining and 8 defective microprocessors, the probability of picking a defective one is;
8/98 = 4/49
From the set of 97 remaining and 7 defective microprocessors, the probability of picking a defective one is;
7/97
Adding all 4 probabilities together, we get;
1/10 + 1/11 + 4/49 + 7/97 = 0.345 or 34.5%
This is the same as finding the sides of a triangle.
12^2 + X^2 = 25^2
144 + X^2 = 625
625 - 144 = 481
481 squared = 21.9317
round that up and you get 22. Hope that helps!
Answer:
x>-7
Step-by-step explanation:
2x+3>-11
subtract 3 on both sides
2x>-14
divide by 2 on both sides
x>-7
Note: When dividing or multiplying by a negative number, be sure to flip the inequality symbol!
Answer:
0.2983
Step-by-step explanation:
Let X be the reading on thermometer. Given that X is N(0,1)
We are to find the probability that a randomly selected thermometer reads between negative 0.12 and 1.02
Reqd probability = 
.
Since this x is already normal std variable x=z
i.e. reqd prob = 
Hence answer is 0.2983
