Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 64
Sample mean = 22.3
Sample standard deviation = 8.8
We want to estimate 92% confidence interval.
92% Confidence interval:
Putting the values, we get,
Degree of freedom = n - 1 = 63
Answer:
The value of x = 18
Step-by-step explanation:
Given the data set
- Given that the median of the data is 18.
- We know that the median is the middle number in a data set when the data points are in ascending order.
As the given data is already in ascending order.
- Please observe that the data set has an odd number of data points, meaning that the middle number is the median of the data is 18.
As 'x' is the middle number, thus it represents the median value.
Therefore, the value of x = 18
Answer:
d = 6t
Time required will be 3 hours.
Step-by-step explanation:
Lakelyn can swim at a rate of 250 yards every 5 minutes. She can run 6 miles an hour and bike 12 miles an hour.
Therefore, her running speed is 6 miles per hour.
Therefore, the function that models the running distance (d) in miles and the time span of running (t) in hours is given by
d = 6t ............. (1)
Using the above equation we can calculate the time required by her to run 18 miles.
So, 18 = 6t
⇒ t = 3 hours. (Answer)
