5+6h=37
Subtract 5 from each side
5+6h=37
-5 -5
-------------------
6h=32
divide both sides by 6
6h=32

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
-14 + x = 5
First, regroup terms. / Your problem should look like: x - 14 = 5
Second, add 14 to both sides. / Your problem should look like: x = 5 + 14
Third, simplify 5 + 14 to get 19. / Your problem should look like: x = 19
Answer: C) 19
Simplified ratio
30: 1
1: 1/30
