A major advantage of longitudinal design over the cross-sectional design is the ability to detect change as a result of repeated

Answer:

Conclusion: The statement is true.

Step-by-step explanation:

A longitudinal design consists of the observation of one or several variables in a group of individuals during a time window, in order to record the possible changes that are generated in said characteristic in that lapse.

On the other hand, the transverse design is concerned with measuring one or several variables at a single point of time and, therefore, does not allow changes to be detected over time.

Conclusion: The statement is true.

Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less than 120.
RSB [31]

Answer:

Inequality : 4x+8 < 120

x<28

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Perimeter of a rectangle (P)= 2 length +2 width

Where:

Width = x

Length = x+4

Replacing with the values given

P = 2 (x+4) + 2x

P = 2x+8+2x

P=4x+8

Since the perimeter of the rectangle must be less than 120:

4x+8 < 120

Solving for x

4x<120-8

4x<112

x<112/4

x<28

Feel free to ask for more if needed or if you did not understand something.

when full the gas tank of a car holds 15 gallons. it now contains 12 gallons. what percent represents how full the tank is?
Masteriza [31]

Hello!

to find the percent of a whole, use this equation here:

(remaining) / (total) = X

X * 100 = %

in this case:

12 / 15 = 0.8

0.8 * 100 = 80

your answer is 80%

I hope this helps, and have a nice day!
