Answer:
Value of x = 16
Step-by-step explanation:
Given:
Mean value = 10
Numbers; 4, 8, x, 12
Find:
Value of x
Computation:
Mean = Sum of all numbers / Total Number
10 = (4 + 8 + x + 12) / 4
40 = 24 + x
x = 16
Value of x = 16
Answer:
X has an element of empty set
just know that it is always true to some extent.
Step-by-step explanation:
To Sketch a graph of each of the four angles of 30°, 150°, 210°, 330°, one can follow the example that is given in the image.
<h3>What is a sketch?</h3>
In the mathematics, a sketch is known to be a given category that tells what a thing is all about.
Note that in sketching, one need to take not of the key points and angles and as such, To Sketch a graph of each of the four angles of 30°, 150°, 210°, 330°, one can follow the example that is given in the image.

Answer: Choice D</h3>
==================================================
Explanation:
We can rule out choice A because the given equation has a negative slope, but the graph in choice A shows a line sloping uphill as you read from left to right (the slope here is positive).
We can rule out choice C because x = 0 should map to y = -4, but instead it maps to y = 4.
Let's see what happens when we plug in x = -2
y = (-3/2)*x - 4
y = (-3/2)*(-2) - 4
y = 3 - 4
y = -1
We can see that x = -2 maps to y = -1. The table in choice B shows x = -2 and y = 1 pairing up, which contradicts what we just found after plugging in x = -2. Therefore, we can rule out choice B.
The only thing left is choice D, which is the final answer. To graph a line like this, all you need are two points. Each point is found by plugging in an x value to get a corresponding paired y value. One point we know is on this line is (0,-4) which is the y intercept. Another point is (-2,-1) which we found earlier above.
