Answer:
The probability that the sample proportion will be less than 0.05 is 0.80511.
Step-by-step explanation:
We are given that a courier service company wishes to estimate the proportion of people in various states that will use its services.
Suppose the true proportion is 0.04 and 349 are sampled.
<u><em>Let </em></u>
<u><em> = sample proportion</em></u>
The z score probability distribution for sample proportion is given by;
Z = 
~ N(0,1)
where, = sample proportion
n = sample size = 349
p = population proportion = 0.04
Now, the probability that the sample proportion will be less than 0.05 is given by = P( < 0.05)
P( < 0.05) = P( < 
) = P(Z < 0.86) = 0.80511
<em>The above probability is calculated by looking at the value of x = 0.86 from the z table which has an area of 0.80511.</em>
Hence, the probability that the sample proportion will be less than 0.05 is 0.80511.
It is given that 
.
Now, know that in 180 degrees there are 
radians. This can be written as:
radians
radians (dividing both sides by 180)
Thus, to find the measure of the given angle of 
in radians, we will have to multiply the above equation by 135. Thus, we get:
radians
radians
Thus, equivalent to the radian measure of angle a is 2.356
1) 
and 
and

2) 
is a parallelogram (a quadrilateral with diagonals that bisect each other is a parallelogram)
3) is a rhombus (a parallelgoram with congruent diagonals is a rhombus)
4) 
(halves of congruent segments are congruent)
Commercial passenger flights always list the time AT THE PLACE where
the event took place. The data you gave in your question means that the
flight departed ORD at 8:00 AM Central (Chicago) Time, and arrived LAX
at 12:00 PM Pacific (Los Angeles) time.
Since the trip spanned two time zones, it was actually in the air for 6 hours.
Average speed = (distance) / (time to cover the distance)
= (1,700 miles) / (6 hours) = (283 and 1/3) miles per hour.
====================================
But that wasn't what you had in mind, was it.
You meant that the flight took 4 hours.
In that case, the average speed was
(1,700 miles) / (4 hours) = 425 miles per hour.
This is a much more reasonable average speed for a long haul
passenger jet airliner.
