Answer:
0.4444
Step-by-step explanation:
Use the following property to ease the calculation:
P(At least one)=1-P(None)
Total number of electrical components: 9
Number that does not function well :1
Number that functions well : 8
We have
ways to to choose 4 good components from 8.
We have
ways to choose 4 components from a total of 9.
If all function properly then none is bad, we
way to do this.
P(At least one)=
P(At least one)=
P(At least one)=0.4444
Answer:
2/3, 1,2,4
Step-by-step explanation:
y = mx + b
When a function is reflected over the y-axis, the b (2) stays the same but the slope (m) changes to its opposite sign.
since the slope is negative in this equation, it will become positive.
so the new fuction will be
y = 5x + 2
