Answer:
The degrees of freedom for this sample are 27.
The sample size to get a margin of error equal or less than 0.3656 is n=4450.
Step-by-step explanation:
The degrees of freedom for calculating the value of t are:
With 27 degrees of freedom and 95% confidence level, from a table we can get that the t-value is t=2.052.
The sample size to get a margin of error equal or less than 0.3656 can be calculated as:
Answer:
72 inches
Explanation: because if you divide 72 by 12 you would have 6 and that would be 6 feet
I set it up as an equation. 1/4x = 1/7x + 3. After you solve it out, it’s 28.
Answer:
D,
Step-by-step explanation:
the volume of a sphere is 4/3πr^3
For a line to be parallel to another line, the slope must be the same.
The line given is y = 3x - 5 , so the other line's slope has to be 3.
so your answer would be A. y = 3x + 5.
