Answer:
Don't spin the barrel.
Step-by-step explanation:
Each time you spin the barrel, the probability A of finding a bullet, having two bullets in six chambers is:
For you to get shot in the second try but not the first, the barrel spin would have to stop precisely at one specific chamber: the one right before the bullets, so that probability would be:
which means that this event is half as likely as finding a bullet every time the barrel is spun. Your chances are better if you pull the trigger for the second time without spinning the barrel.
Answer:
(-16.494 ; -3.506)
Step-by-step explanation:
student Prob A Prob B difference, d (A-B)
1 20 35____ - 15
2 30 40 ___ - 10
3 15 20 ___ - 5
4 40 50 __ - 10
Difference, d = -15, -10, -5, -10
Xd = Σd/ n = - 40 / 4 = - 10
Standard deviation of d ; Sd = 4.082
The confidence interval for the difference is given as :
Xd ± Tcritical*(Sd/√n)
Tcritical at 95%; df = n - 1 ; 4 - 1 = 3
Tcritical(0.05, 3)). = 3.182
C.I = -10 ± 3.182(4.082/√4)
C.I = -10 ± 6.494462
C. I = (-16.494 ; -3.506)
I got x=-3.
Simplify both sides of the equation, then Isolate the variable.
Hope this helps! :D
Answer:
5. 4 6. 6
Step-by-step explanation:
Number 5
Subtract the numbers: 10 - 6 = 4
Number 6
![70-\left(\sqrt[3]{64}\right)^3](https://tex.z-dn.net/?f=70-%5Cleft%28%5Csqrt%5B3%5D%7B64%7D%5Cright%29%5E3)
![\left(\sqrt[3]{64}\right)^3=64](https://tex.z-dn.net/?f=%5Cleft%28%5Csqrt%5B3%5D%7B64%7D%5Cright%29%5E3%3D64)
Subtract the numbers: 70 - 64 = 6
