The correct answer to your question is (6)!! hope its correct
It means 25 divided by 0.2
Answer:
Variance = 3.6 voteres
Step-by-step explanation:
Probability of favour voters, P = 0.22
Total number of voters, n = 21
The probability of voters who are in not favour of new hospital construction = 1 - P
The probability of voters who are in not favour of new hospital construction = 1 - 0.22
The probability of voters who are in not favour of new hospital construction, P* = 0.78
Variance = n x p* x (1 - p*)
Variance = 21 x 0.78 x 0.22
Variance = 3.6 voters
X= -9y+32
3(-9y+32)+4y = 4
-27y+96+4y= 4
-23y+96 =4
-23y= —92
y= 4
x= -9(4)+32
x=-36+32
x= -4
