Answer: 30.2
Explanation:
The mean is calculated by taking the sum of the values and dividing by the count.
For instance, for the 6 women, with the mean being 31, we can see that the ages summed to 186:
186
6
=
31
And we can do the same for the men:
116
4
=
29
And now we can combine the sum and count of the men and women to find the mean for the office:
186
+
116
10
=
302
10
=
30.2
Step-by-step explanation:
Answer:
a) 
b) 
Step-by-step explanation:
a) We have the following equation:
(1)
Where 
is the time is seconds, 
is the distance in meters and 
is the acceleration due gravity
If we divide numerator and denominator inside the square root by 2:
We will have:
Hence:
b) Using the same equation (1) with thw following data:
We will have the reaction time:
Given both the distance from the tree and the height of the tree, the angle of elevation can be obtained using the tangent formula, tangent theta = opposite side / adjacent side. In this case, opposite side = the tree's height and the adjacent side is the distance of Cisco to the tree. Therefore, the angle of elevation equals 40.03 degrees.
