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:

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.

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

Work out 5/8−2/5 Give your answer in its simplest form.

Answers

(5)/(8) - (2)/(5)

First, find the LCD (least common denominator) of the two fractions.
List the multiples of each denominator and find the one that is common.
Multiples of 8: 8, 16, 24, 32, 40
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40
40 is your LCD.

Second, what can you divide by to make the denominators of each fraction '40'? Whatever you do to the bottom you must do to the top.
(5*5)/(8*5) - (2*8)/(5*8)

Third, multiply.
(25)/(40) - (16)/(40)

Fourth, since the denominators are the same now, we can combine them.
(25-16)/(40)

Fifth, subtract '25 - 16' to get 9.
(9)/(40)

Since (9)/(40) is already in the simplest form, it is your answer.

Answer as fraction: (9)/(40)
Answer as decimal: 0.225

PLEASE HELP MEEEENelson went to the Taste of Tacos, a festival where people come to taste a variety of tacos. The festival charges an admissions fee to attend and then charges $3 per taco. By the end of the festival, Nelson spent a total, y, of $30 and purchased 6 tacos, x. Write an equation in slope-intercept form to represent this.

Answers

Answer:

\sf y = 3x + 12

Step-by-step explanation:

Definition:

The slope-intercept form of a linear equation is a way of writing a linear equation in which the y-intercept and the slope of the equation are explicitly represented. The y-intercept is the point where the line crosses the y-axis, and the slope is the rate of change of the line.

The slope-intercept form of a linear equation is:

\boxed{\sf y = mx + b}

where:

  • m is the slope of the line
  • b is the y-intercept of the line

In this case, the slope of the line is $3, because Nelson pays $3 for each taco he purchases.

The y-intercept of the line is the admission fee, which we do not know. Therefore, we can write the equation as follows:

\sf y = 3x + b

To find the value of b, we can use the fact that Nelson spent a total of $30 and purchased 6 tacos. This means that the point (6, 30) is on the line.

We can substitute these values into the equation and solve for b:

30 = 3(6) + b

30 = 18 + b

b = 30 - 18

b = 12

Therefore, the equation that represents the total amount of money Nelson spent, y, in terms of the number of tacos he purchased, x, is:

\sf y = 3x + 12

Step-by-step explanation:

To represent Nelson's expenses at the Taste of Tacos festival with an equation in slope-intercept form (y = mx + b), where y is the total cost and x is the number of tacos purchased, we can break down the cost into two components:

  1. The admission fee, which is a fixed cost (b).
  2. The cost per taco, which is $3 (the slope or rate, m).

Given that Nelson spent a total of $30 and purchased 6 tacos, we can set up the equation as follows:

Total Cost (y) = Cost of Admission Fee + Cost of Tacos

y = b + 3x

Now, we know that the total cost (y) is $30, and the number of tacos (x) is 6. Substituting these values into the equation, we get:

30 = b + 3(6)

Now, solve for b:

30 = b + 18

To isolate b, subtract 18 from both sides of the equation:

b = 30 - 18

b = 12

So, the equation in slope-intercept form representing Nelson's expenses at the festival is:

y = 3x + 12
