In order to find the average you have to add up all the data values and then find the sum of the data values.
So on average he ran about 82.5 miles.
Answer:
A sample size of 6755 or higher would be appropriate.
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 M is given by:
90% confidence level
So , z is the value of Z that has a pvalue of , so .
52% of Independents in the sample opposed the public option.
This means that
If we wanted to estimate this number to within 1% with 90% confidence, what would be an appropriate sample size?
Sample size of size n or higher when . So
A sample size of 6755 or higher would be appropriate.
Answer:
<em>$18.40</em>
Step-by-step explanation:
(find the tip)
$32 x 15% = $4.80 (tip)
Total bill:
32 + 4.80 = 36.80
Each girl paid:
36.80 / 2 = $18.40
The roots of f(x) are the values for x at which f(x)=zero. The root of f(x) at point P is a bit redundant, since point P is the root of the function (and based on the graph, the only root).
We could plug zero in for f(x) to find the value of x at Point P, but based on the graph/options provided and the complexity of the function, it may be easier to just eyeball the graph to get the correct answer. We see that point P is between 1/2 and 1 on the x-axis.
Of the options provided, we want the value for x that satisfies: 1/2 < x < 1
a) 1/2 < 3/5 < 1 CORRECT ANSWER
b) 1/5 < 1/2 INCORRECT
c) 5/3 > 1 INCORRECT
d) 1/3 < 1/2 INCORRECT
