How could you graph an inequality like this x>3?
1 answer:
Answer:
see below
Step-by-step explanation:
The graph of it on a number line is an open circle at x=3 with a line extending to the right through larger numbers.
When the inequality does not include the "or equal to" case, the boundary is graphed as a dashed line (on an x-y plane) or open circle (on a number line). The shaded area covers values of the variable that meet the condition of the inequality. Here, those are values of x that are more than 3.

Step-by-step explanation:
From the question we are told that:
Population mean
Population standard deviation
Sample size
Generally the equation for Standard error is mathematically given by
We know the opposite side (10) and the adjacent side (7), so we can use tangent to find angle B. Since tan = opposite side/adjacent side, we can set up this equation: tan(B) = 10/7. We can get B on its own by making the equation this: 
Now, we plug this into our calculator to get:
B = 55°, so angle B is 55°.
