Answer:
1. x= 3 - y, y= 3 - x
2. x= 5/6 + y/6, y= -5 + 6x
Step-by-step explanation:
To solve for x, move all terms that dont contain x to the right side and solve
To solve for y, move all terms that dont contain y to the right side and solve
Answer:
a) 39
b) 64
Step-by-step explanation:
a) in order to know how many residents of the country that are 25 years old or older do you expect to randomly select? we say ;
Let the number of residents be x
0.26*x >=10
x >= 10/0.26 = 38.46
~ 39
b) in order to know How many residents of the country 25 years old or older do you have to randomly select to have a probability 0.985 that the sample contains at least 10 who have earned at least a bachelor's degree we say;
P(at least 10 out of 9) =1-P(at most 9 ) =0.983
solving above : number of randomly selected residents = 64
