Answer:
30 degrees
Step-by-step explanation:
90 + 60 + x = 180
150 + x = 180
-150 -150
x = 30

Answer:
54 inches = 1.3716 meters
Step-by-step explanation:
Question is a bit vague. If you wish to graph this inequality, you'll need to know what the graph of the absolute value function y = |x| looks like; it's a " V " with the vertex at the origin. The slope of the right half of the graph is m=1. Draw this function.
Next, subtract 2 from both sides. We'll get <span> |x + 1| < –1 - 2
or
</span> |x + 1| < –3. We can stop here! Why! because the absolute value function is never smaller than zero, and so <span> |x + 1| is never smaller than -3.
You could, of course, graph y = |x+1|; start with your graph for y = |x| and then move the whole graph 1 unit to the left (away from the origin). If you do this properly you'll see that the entire graph is above the x-axis, except for the vertex (-1,0). Again, that tells us that the given inequality has no solution.

Answer:
Step-by-step explanation:
The missing parameters are:
--- population
--- population mean
-- population standard deviation
Required
First, calculate the sample standard deviation
Next, calculate the sample mean 
So:
So, we have:
Calculate the z score
So, we have:
From the z table
So:
