PLZ HELP ME :(

Mathematics
1 answer:
Zanzabum3 years ago
4 0

Answer:

A. The stratified sample assures that the opinions of employees from both locations will be represented.

Explanation:

This option is correct, because it ensures that the results of the survey represent employees' opinions from both rural and urban locations. Gathering employees' opinions from both locations will furthermore ensure that any policy dependent on the results of this survey not only represent urban employees' interests (as they are the majority), but also the rural employees' interests.

Option B is incorrect as a stratified sample will be <em>more </em>expensive to implement than a simple random sample and will <em>not necessarily help to</em> save money over time.

Option C does not apply as it is simply an assumption that has no evidence to support it.

Option D is incorrect as a stratified sample in this case is better than a random sample in generating results that are more representative of the store's employees from both locations.

The sum of all the angles in a triangle is 180°.
There is a right angle -> a 90° angle on the hypotenuse of the largest triangle (the largest being the one that contains both smaller triangles)

To solve this problem, you don't really need to solve y.
Next to the 48° angle, you have two of the same angles, both x variables.
The sum of these three angles has to be 180°48 + 2x = 180 \\ 2x = 180 - 48 \\ 2x = 132 \\ x = 66

Now that we have x, we can calculate the value of z.
We add the value of x and the 90° angle, we later subtract it from 180°

Calculating the value of z:
66 + 90 = 156 \\ 180 - 156 = 24 \\ z = 24

If you really want to know the value of y, you just add up the 90° angle and the 48°, then subtract that from 180°
90 + 48 = 138 \\ 180 - 138 = 42 \\ y = 42
