According to the described situation, it is found that:
1. 
, 
.
2. Since the interval does not include 32, hence you can reject the null hypothesis and there is enough evidence to conclude that the actual mean flight time of all balloons differ from the advertised 32 hours.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if the mean flight time is of 32 minutes, that is:
At the alternative hypothesis, it is tested if it differs of 32 minutes, hence:
<h3>What is the decision?</h3>
The confidence interval is of (28.5, 31.4), that is, is does not include 32, hence you can reject the null hypothesis and there is enough evidence to conclude that the actual mean flight time of all balloons differ from the advertised 32 hours.

Answer:
<em>x = 32</em>
Step-by-step explanation:
This is an isosceles triangle since two sides have length 10. The angles opposite the congruent sides are congruent. There is an angle measuring 116 deg, and two angles measuring x. The sum of the measures of the angles of a triangle is 180.
x + x + 116 = 180
2x + 116 = 180
2x = 64
x = 32
Given Ratio
-------------------
16 : 4
16 ÷ 4 : 4 ÷ 4 ← Divide by 4 on both sides
4 : 1
------------------------------------------------------------------------
Answer: Yes, 16: 4 and 4: 1 are proportional.

Answer:
i really donr know
Step-by-step explanation:
im so sorry
The bottom of the ladder is 10.5 feet away from the wall
Step-by-step explanation:
The given scenario forms a right triangle.
Where
The length of ladder will be the hypotenuse
The wall on which the window is situated will ebt he perpendicular and
The distance between the foot of ladder and the wall will be the base
So,
Hypotenuse = H = 20 foot
Perpendicular = P = 17 feet
Base = B = ?
Using the Pythagoras theorem
The bottom of the ladder is 10.5 feet away from the wall
