Answer:
The correct option is stratified sampling
Step-by-step explanation:
Stratified sampling is a sampling techniques that divide a population into strata which is homogeneous and then simple random sampling (SRS) is then applied in each stratum to get the required samples.
Looking at the question, the population has been divided into strata I.e those majoring in communication, those majoring in business, and those majoring in history, then simple random sampling is then applied to pick the required samples.
Answer:
tan x = 5/12
Step-by-step explanation:
given:
- sin x = 5/13
- cos x = 12/13
to find
- tan x
solving
tan x = sin x / cos x
tan x = (5 / 13) / (12 / 13)
tan x = 5 / 12
Answer:
As you may know, the addition of all the interior angles of a triangle always adds up to 180°.
So if we know two angles of the triangle, A1, and A2, we can find the third angle as:
A1 + A2 + X = 180°
X = 180° - A1 - A2.
Se with only knowing two angles, we can find the third angle.
So aaa is a criteria equivalent to aa.
Now, the problem with this criteria is that also works for finding similar triangles (for example, an equilateral triangle of sides 10 and an equilateral triangle of sides 20 are similar, as the angles are the same, but are not congruent, as the length of the sides is different) and this happens because we only have information of the angles and know nothing of the sides.
X = 7 + staci since 7 more cats added to x is stacis amount
