Answer: Hello your question is incomplete attached below is the complete question
answer:
i) 0.8 , standard error = 0.0516
ii) 0.39, standard error = 0.0425
Step-by-step explanation:
i) proportion of Juveniles reference for females ( f )
= x₁ / n₁ = 48 / 60 = 0.8
standard error =
= 0.0516
ii) Proportion of Juveniles reference for males ( m )
= x₂ / n₂ = 52 / 132 = 0.39
standard error =
= 0.0425
The quadratic formula is (-b+-sqrt(b^2-4ac))/(2a)
In your equation,
A=2
B=-10
C=7
Plugging these in we get
(10+-sqrt(100-4(2)(7)))/(2*2)
=(10+-sqrt(44))/4
=(10+-6.633)/4
=16.633/4 or -3.366/4
=4.158 or -0.841
Final Answer:
x=4.158 or x=-0.841
Hope I helped :)

<h2>Step-by-step explanation :</h2>
Total shared part:
1/4 + 1/8
Taking LCM and adding:
2/8+1/8
Adding gives:
3/8
