You would do 2 times 6 and get 12. Then you subtract 12 from -20 and you get -8. so -8 is your answer.
Answer:
The diameter of the hole is 20.04 ± 0.01 cm
The diameter of the piston is 19.92 ± 0.04 cm.
We are given that The clearance is one-half the difference between the diameters.
So, Clearance = 
= 
Uncertainty in the estimate = 
=
So, Clearance with uncertainty is 
Hence the clearance is 0.06 and the uncertainty in the estimate. is 0.025
Based on the venn diagram of siblings, the probability of being an only child or having only sisters is d. 0.50.
<h3>What is probability of being an only child or having a sister?</h3>
The probability of being an only child or having a sister can be found as:
= (Number of those only sister + Number of only children) / Total number of people in poll
Solving gives:
= (8 + 7) / (8 + 10 + 5 + 7)
= 15 / 30
= 0.50
In conclusion, the probability of having a brother and sister is 0.50.
