6x - 15 = 75 (Third Equation)
6x = 90
x = 15 ✅
x + (x - 10) = 26 (Fourth Equation)
x + x - 10 = 26
2x - 10 = 26
2x = 36
x = 18 ✅
5x - 3x = 10 (First equation)
2x = 10
x = 5 ✅
2(2x - 1) = 46 (Second equation)
4x - 2 = 46
4x = 48
x = 12✅
Answer:
0.7455
Step-by-step explanation:
First, we note that there are C
= 220 ways of selecting the defective items.
The probability that the inspector will have to test at least 9 widgets would be 1 minus the probability that the inspector will have to test 8 or less widgets.
This is 1 - P(8 or less widgets have to be checked)
1 - 
= 1 - 56/220
= 1 - 0.2545
= 0.7455
