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:
1 ten and 3 ones
Step-by-step explanation:
ten + three is 13. Hence, one ten and three ones.
1.5*100% = 150%
The book is worth 150% of the original amount.
Answer:
d) the slope of f(x) is greater than the slope of g(x)
Step-by-step explanation:
to find the slope of an equation, you look at its rise/run. for f(x), you can see that from one point (0, 3) to another (1, 1) it goes down 2 values (3 - 1) and over 1 value (0 + 1). because it goes down 2 values, the rise is -2, and because it moves to the side 1 value positively, the run is +1.
-2/+1 = -2. this means the slope of f(x) = -2.
finally, it says the slope of g(x) = -6, and -2 > -6. i hope this helps! :)
