It is found that there is a relationship between the weight of an airplane and the maximum speed it can travel. The results were published claiming that a lighter airplane can travel faster. What is the problem with reporting the result this way?

Answers

Answer 1

Answer:

Answer:

Missing data or correlation and causality

Step-by-step explanation:

The results of a hypothesis should always be very accurate and display the research data that allowed us to reach the presented result. The lack of data, correlation and causality do not give the search result credibility because it does not show the factors and variables that show that the result is correct. This is the problem of the result stated in the question. The result is that lighter aircraft can travel faster, but it does not say the data, nor the variables and situations that led to this conclusion.

Answer 2

Answer: planes could not go if the airplane is to heavy or slow so that is why they both matter

A restaurant sells only two desserts,pie and cake.A piece of pie cost $4.A piece of cake cost $5.The restaurant sells 100 desserts,which cost a total of $473.How many pieces of pie did they sell (HELP NEEDED FAST)

Answers

Let p and c be the pieces of pie and cake respectively.

We have p+ c= 100 (because the total number of pieces of pie and cake is 100).

On the other hand, we have $4p+ $5c= $473
or 4p+ 5c= 473

p+c=100
4p+5c=473

Solving the set of equations above, we have: p= 27, c=73.

They sold 27 pieces of pie~

pie = x
cake = y

x + y = 100
4x + 5y = 473
4x + 4y = 400
substract it
y = 73

x + y = 100
x + 73 = 100
x = 100 - 73 = 27
