Answer:
3/2
Step-by-step explanation:
First, you find the mean (((4 + 5 + 6 + 1)/4) = 4)
Find the absolute difference between each data value and the mean: 0, 1, 2, 3
Add the differences (in the previous step) and divide by number of terms: (0+1+2+3)/4 = 6/4 = 3/2
Answer:
Inverse = (arcos x) / 2.
Step-by-step explanation:
y = cos 2x
2x= arcos y
x = (arcos y) / 2.
Inverse = (arcos x) / 2.
The large box is 45 pounds and the small is 20 pounds
For On call = 10/3.5 = $2.85 for per hour
For talk time 1.25/1/2= $2.5 for per hour
Answer:
It is 40 degrees.
Step-by-step explanation:
You can start off by understanding this is not a right angle (exactly 90 degrees, think of a corner of a room) or and obtuse angle (more than 90 degrees, bigger than a right angle). With that information we know that it is an acute angle (less than 90 degrees, smaller than a right angle). With that we have 40 and 50 degrees left. When you compare the angle with the 40 degrees one, it is the same size. The angle 1 is a reflection of the triangle with the 40 degrees angle. Hope this helps :)
