11+6=17 17÷2= 8.5 hours so the answer would be 4:50pm. Maybe
For number 5: 180 -139 = x
For number 6: x = 41
For number 7: x + 18 = 90 (not 100% sure)
For number 8: x = 72
For number 9: you could write an equation about an acute angle and divide it into 2 parts the have one side 3 + 8 and have the other x. Then you could go from there. I’m sorry if you can’t figure out number 9. I tried to think of something.
Answer:
0.15866 is the probability of the average fracture strength of selected 100 pieces of glasses that of exceed 14.3.
Step-by-step explanation:
Given that, the strength of a tempered(x) a glass has average 14.1 and has standard deviation 2.
, 
n=number of selected pieces= 100.
The probability that the average fracture strength of 100 pieces of this glass exceed 14.3 is



= 1 - 0.84134
=0.15866.
Answer:

Step-by-step explanation:
Replace y with f(x).

Swap x and y and solve for y
