Answer: 
Step-by-step explanation:
Given
Vertex of the parabola 
Focus of the parabola 
As the x coordinate of vertex and focus is same and focus lie below the vertex, therefore the parabola is the type of
distance between Vertex and focus is 1 unit
Parabola becomes
The sides must be equal otherwise BC and AD wouldn't be parallel. So
12x-6 = 2x+7
10x = 13
x = 13/10 = 1.3
Answer:
<em>Null Hypothesis : </em> P = 0.73
Alternative Hypothesis : P≠ 0.73
Step-by-step explanation:
<u><em>Explanation</em></u>:-
According to a recent survey, 73% of college students did not use student loans to pay for college
Let p be the proportion of college students who did not use student loans to pay for college
Population proportion P = 73% or 0.73
<u><em>Null Hypothesis :</em></u> P = 0.73
Alternative Hypothesis : P≠ 0.73
