Using the t-distribution, the critical value needed is: t = 2.2622.
<h3>How to find the critical value for the t-distribution?</h3>
The critical value is found using a calculator, with two parameters:
- The number of degrees of freedom, which is one less than the sample size.
For this problem, we have a confidence level of 95% and 10 - 1 = 9 df, hence the critical value is t = 2.2622.

Answer-44
You can turn both of the denominators ( bottom numbers on the fractions ) into 120 ( the whole number ) and the top numbers can be multiplied by how many times the denominators went into 120. Then add the top numbers which equals 76 and then 120-76=44. Hope that kinda helps !!
Answer:
29.4 degrees
Step-by-step explanation:
a = 53 cm = opposite side to the angle
b = 94 cm = adjacent side to the angle 
tan = opp/adjacent = 53/94 = 0.5638
= inverse tangent of .5638 = tan⁻¹ (.5638) = 29.4₋⁰
