Answer:No,random sampling technique will not fit this scenario.A stratified sampling technique will be more appropriate.
Step-by-step explanation:
The random sampling technique is basically used when datas to be selected such that all members of the population has an equal chances of being selected.so any random pick is taken as a representative of the sample.
When categorization is required,then stratified sampling technique is more appropriate i.e the sample are picked careful ly from the two homogeneous classes as a representative of the sample .
Answer:
60°-30°-90° right triangles

Answer: 25.9</h3>
========================================
x = length of AB
The parallel bases of the trapezoid can be added up, and divided over 2, to get the length of the midsegment. The midsegment is the line that cuts the nonparallel sides (or legs) of the trapezoid in half. The midsegment is parallel to the bases.
So,
(AB+DC)/2 = MN
(x+11.5)/2 = 18.7
x+11.5 = 2*18.7
x+11.5 = 37.4
x= 37.4-11.5
x = 25.9
AB = 25.9
Back at the city with the bar and the milkshakes
3. if there were less than 3 acute angles, the triangle would be either obtuse or right.
