Answer:
If two quantities are proportional, then they have a constant ratio. If the ratio is not constant, the two quantities are said to be non-proportional.
Answer:
W
Step-by-step explanation:
To be a function, each input value can only go to one output
X has x=0 going to y=4 and y=6
Y has x=6 going to y=-2 and y =15
Z has x=4 going to y=0 and y =3
W is the only one that has each input going to only one output
Answer:
40%
Step-by-step explanation:
20 out of 50 simplifies to 2 out of 5 which is equivalent to 4 out of 10 which is also 40 out of 100 which is 40%.
Answer:
A) 8%
Step-by-step explanation:
A confidence interval of proportions has an upper end and a lower end.
The margin of error is the difference between these points divided by two. Also, it is the upper end subtracted by the estimated proportion, or the estimated proportion subtracted by the lower end.
In this problem, we have that:
Upper end: 0.68
Lower end: 0.52
Margin of error
The margin of error is 8%.
So the correct answer is:
A) 8%
