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
3:7:8 (divide each number for five)
<h3>Given:</h3>
<h3>To find:</h3>
The size of the unknown angle "x"
<h3>Solution:</h3>
The given polygon is a Pentagon so the sum of interior angle will be,

n means the number of sides
Let's substitute the values according to the formula.


Now, we can find the sum of one interior angle.

n means the number of sides.
Let's substitute the values according to the formula.

<h3>
Answer:</h3>
50
<h3>
Step-by-step explanation:</h3>
These numbers are double those of the (7, 24, 25) triple. 2×25 = 50.
You can also figure it out from ...
... x = √(14² +48²) = √(196 +2304) = √2500 = 50
