Ответ:
0.9444
Step-by-step explanation:
Given: The proportion of politicians are lawyers : p =0.56
Sample size : n = 564
Let q be th sample proportion.
The probability that the proportion of politicians who are lawyers will differ from the total politicians proportion by greater than 4% will be :-
Hence, the required probability = 0.9444
Ответ:
Option B
Step-by-step explanation:
Given the corrected equations from the comment:
Y = -1/2x - 1
Y = 1/4x - 4
(I am assuming from the answer choices that the 1/2 is negative)
Use a graphing tool to graph the given equations.
When graphed, the lines pass the point (4, -3).
See graph below.
Option B should be the correct answer.
Hope this helps.
