Answer:
The speed of one plane = 257.5 miles per hour
And speed of second plane = 332.5 miles per hour
Step-by-step explanation:
We have given,
Distance between two cities = 960 miles
Two planes are flying towards each other.
Let the speed of one plane be x.
Then,
Speed of second plane = x+75 {Following this "one of the planes' speed exceeds the other by 75 mph"]
After 1.5 hours they are still 75 miles apart.
i.e Relative distance between two planes = Relative speed of plane × Time
Here
relative speed = x + (x+75) , and relative distance left to cover = 960-75.
i.e
(960 - 75) = {x+(x+75)}×1.5
885 = (2x+75)×1.5
or 
or 590-75 = 2x
or 515 = 2x
or x = 
= 257.5
Hence the speed of one plane = x = 257.5 miles per hour
And speed of second plane = (x+75) = 257.5 + 75 = 332.5 miles per hour
Answer:
The sampling technique used is convenience sampling.
Step-by-step explanation:
Convenience sampling technique is a method of non-probability sampling that is done using the most easiest sample or the most convenient sample.
For instance, sampling the people of our neighborhood, or school or company, etc.
This type of sampling is known as non-probability sampling because each individual\participant does not have a specific probability of selection. Whereas in case of probability sampling each participant has an equal probability of being selected.
Survey that are conducted through online portals or online survey use samples that are quite easy to collect. The sample collected through online surveys is convenience sample.
The survey conducted to determine how many people were in favor of stricter gun control uses a convenience sampling technique. As it uses the most easy source to collect the sample.
Thus, the sampling technique used is convenience sampling.
Answer:
Make use of GCF Calculator to quickly find the Greatest Common Factor of numbers 90, 104 i.e. 2 largest integer by which both the numbers can be divided. Greatest common factor (GCF) of 90 and 104 is 2
Answer:
≈
Step-by-step explanation:
Find the distance between the three pairs first using the distance formula:
Take the first two points, 
and insert the values:
Simplify parentheses (two negatives makes a positive):
The distance between the first two points is 5. Use the nest two points, 
and insert values:
Simplify parentheses:
The distance between the nest two point is about 4.5. Use the remaining two points, 
and insert values:
Simplify parentheses (two negatives makes a positive):
The distance between the last points is 5. Add the distances together to find the perimeter of the triangle:
The perimeter is about 14.5.
The volume of the rectangular prism is 160. You just multiply the width by the height by the length in order to get the volume of a rectangular prism.
