It will be c. 2x because x+2x = 3x, and if you add that by 2x it will give you 5x.

7,500,000,000,000 it think
Step-by-step explanation:
Answer:
36
Step-by-step explanation:
it is given that there are total of 80 students
in German language there are 25 students
in French language there are 15 students
13 studying Spanish language
in German and French language there are 3 students
in French and Spanish language there are 4 students
in German and Spanish language there are 2 students
3 are studying all three languages
from the given bellow ven diagram
it is clear that the number of students that are not studying any languages are =80- (20+3+8+4+2+7)=36
Find slope: (y2-y1)/(x2-x1)
(-7-1)/(0-2) = -8/-2 = 4
Slope int form: y = mx + b
Y = 4x + b
Plug in a point
1 = 4(2) + b, b = -7
Equation: y = 4x - 7
Answer:
D. It is the method that is most likely to give a true representative sample.
Step-by-step explanation:
The advantage of selecting a random sample is that is without bias, so being a true representative sample.
For example, if you want to estimate the proportion of the population of a certain city that is going to vote for a candidate in the elections, you must select at a place where different people passes, not one uniform place like a school, just a simple example.
So the correct answer is:
D. It is the method that is most likely to give a true representative sample.
