The empirical rule states that approximately 68/95/99.7% of a normal distribution lies within 1/2/3 standard deviations. So the answer is 68%.
Answer: = ( 0.0384, 0.1216)
Therefore at 95% confidence interval the difference between teenage female and male depression rates is between ( 0.0384, 0.1216)
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 0.08
Standard deviation r = 0.03
Number of samples n = 2
Confidence interval = 95%
z(at 95% confidence) = 1.96
Substituting the values we have;
0.08+/-1.96(0.03/√2)
0.08+/-1.96(0.021213203435)
0.08+/-0.0416
= ( 0.0384, 0.1216)
Therefore at 95% confidence interval= ( 0.0384, 0.1216)
we are given
we can select any values of x
but the values of f(x) depends only on values of x
so, x is independent variable
f(x) is dependent variable
so, x is a input
and
f(x) is output variable or quantity............Answer

Answer:
Given
For the Δ ACB
AC≅BC
∠ADB≅∠BEA
To prove AE≅BD
Solution:
Proof:
Statement Reason
1) AC≅BC Given
2) Δ ACB is an isosceles triangle By definition of isosceles triangle (Triangle with two sides congruent)
3) ∠CAB≅∠CBA By isosceles triangle theorem (The angles opposite to the
congruent sides are congruent.
4) ∠DAB≅∠EBA Angles with same measures
5) ∠ADB≅∠BEA Given
6) AB≅AB Reflexive property (the segment is congruent to itself.
7) ΔADB≅ΔBEA A.A.S.(Angle Angle Side)
8) AE≅BD Corresponding parts of congruent triangles are congruent.
Hence proved.
