Answer:
+/- 1.9983
Step-by-step explanation:
The critical values for a confidence interval for the population mean, with population standard deviation not known, are obtained from the student's t distribution.
The sample size is given as 64. The degrees of freedom will thus be;
sample size - 1 = 64 - 1 = 63
The confidence level is given as 95%. The level of significance will thus be;
100 - 95 = 5%.
The area in the right-tail will thus be 2.5%. Therefore, we looking for a t-value such that the area to its right is 2.5% and the degrees of freedom being 63. From the t-tables we have;
+/- 1.9983
Answer:
<h2>
<em><u>30°F</u></em></h2>
Step-by-step explanation:
Simply subtract 15 from 45 and you are left with 30. Hope this helps you!
The question ask to calculate or find the limit when x approaches 0 from the right when int x/x. Base on the said problem and understanding the said equation and variables, I would say that the limit would be X>0. I hope you are satisfied with my answer and feel free to ask for more
Answer:
B, 6
Step-by-step explanation:
In the equation (x - c)² + (y - d)² = r², (c, d) is the center and r is the radius. In this case, c = -2, d = 7 and r = 6 so the center is (-2, 7) and the radius is 6.
