Given:
u varies directly with the square of p and inversely with d.
To find:
The equation for the given situation.
Solution:
If y is directly proportional to x, then
If y is inversely proportional to x, then
It is given that u varies directly with the square of p and inversely with d. So,
It can be written as:
Where, k is the constant of proportionality.
Therefore, the required equation is .
Answer:
The magin of error is 0.0552 = 5.52 percentage points.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
For this problem, we have that:
99.5% confidence level
So , z is the value of Z that has a pvalue of , so .
M.E:
The magin of error is 0.0552 = 5.52 percentage points.
Answer:
The free show shooters are likely to be successful after ten attempts
Step-by-step explanation:
Being successful 85% of the time means they have a probability of 85/100 = 0.85
This is for the free throw shooters
for the hitters, there is an average of 0.42
Looking at the two, 0.85 is a better probability compared to 0.42
This is because it is closer to 1
What this mean is that after 10 throws, it is possible that the free throw shooters are likely to be successful since they have the better probability
Answer:
Quadrant 1
Step-by-step explanation:
Because (4,7) has both positive coordinates. Quadrant 1 is the only quadrant that can have both positive coordinates
