Step-by-step explanation:
It is given the average cost of the flight nationwide is $ 445.99
I wanted to 
to determine that the true average is greater than $ 445.99
Let the hypothesis that the true average is actually greater than $445.99
Therefore,
the 
for the test is :

The properties of a Circle with their definitions are; As highlighted below
<h3>How to identify Properties of a Circle?</h3>
1) The distance around a circle is called; Circumference
2) A portion of the circumference of a circle is called; Arc Length
3) The distance from the center to any point on a circle is called; Radius.
4) The distance through the center between points on a circle is called; Diameter
5) The degree measurement of an arc (in reference to its central
angle) is called; Arc Measure
6) An arc which measures less than 180° is called; Minor arc
7) An arc which measures exactly 180° is called; Semi Circle

Answer:
f(0) = 0.25 = 1/4
f(x) = f(x-1) × 2/3
Step-by-step explanation:
a0 = 0.25×(2/3)⁰ = 0.25×1 = 0.25 = 1/4
a1 = 0.25×(2/3)¹ = 0.25×(2/3) = 1/4 × 2/3 = 2/12 = 1/6 =
= a0 × 2/3
a2 = 0.25×(2/3)² = 0.25×(4/9) = 1/4 × 4/9 = 4/36 = 1/9 =
= a1 × 2/3
=>
an = an-1 × 2/3, n >= 1
but what about negative x ?
is a0 = a-1 × 2/3 ?
so, yes, a0 = a-1 × (2/3)
and a-1 = a-2 × (2/3)

Answer:
A=20 degrees
D=70 degrees
E=110 degrees
Step-by-step explanation:
A=20 because a right angle always = 90 so 90-70=20
D=70 because I believe that angles C and D make a right angle, and C = 20 degrees, so we now subtract. 90-20=70
E=110 because D and E = a straight line, which is 180, and sense D is 70 degrees, all we need to do is subtract. 180-70 is 110, so our answer is 110
Hoped this helped, and let me know if I messed up somewhere.
The answer is -1/3, -5/12, 0.66
