Answer:
The answer is (d)= Selecting a simple random sample from each of a given number of strata formed from the elements in the population.
Stratified random sampling is a sampling method where the population has a number of distinct categories. The population can be organized into separate strata and each stratum is then sampled as an independent sub-population out of which individual elements can be randomly selected. In this case, each unit in a stratum, that is, each element in a group has the chance of being selected into the sample and there is adequate representation of minority sub-groups. With Stratified sampling, the best result occurs when elements within strata are internally homogeneous.
Step-by-step explanation:
7.750 and 7.7500 are 2 equivalent fractions.
37.6*9.25=$<span>347.8 without deductions</span>
The most reasonable estimate for the height of a two-story house is "15 meters".
The 15 centimeters is not reasonable, it is too small. While the 15 kilometers is not also reasonable since it is too big. Kilometers is used for long distance.
ANSWER
B. 310°
EXPLANATION
The sum of angles in a circle is 360°
From the diagram, the measure of arc SY is 50°
The measure of arc STY plus the measure of arc SY is 360°
To find the measure of arc STY, we subtract 50° from 360° to get:
Measure of arc STY
This simplifies to
The correct answer is B 310°
