The probability that demand is greater than 1800 gallons over a 2 hour period is : 0.5

<u>Given data :</u>

Mean value of gasoline per hour = 875 gallons

Standard deviation = 55 gallons

<h3>Determine the probability of demand being greater than 1800 gallons over 2 hours </h3>

Demand for gas in 1 hour = X₁

Demand for gas in 2 hours = X₁ + X₂

Therefore ; ( X₁ + X₂) ~ N ( u₁+u₂, sd₁² + sd₂² )

In order to  calculate probabilities for normals apply the equation below

Z = ( X- u ) / sd

where : u = 1800, sd = √ ( 55² + 55² ) = 77.78

using the z-table

P( Y > 1800) = P( Z > ( 1800 - 1800 ) / 77.78)

                    = P( Z>0 ) = 0.5

Hence we can conclude that The probability that demand is greater than 1800 gallons over a 2 hour period is : 0.5.

Answer:

The correct answer is Contrast and repetition.

Explanation:

Contrast: it has to do with sensory stimuli that allow highlighting elements or areas in a composition through the opposition or difference between them, that is, in a graphic design, a contrast is generated when there is a notable difference between two elements.

Repeat: the repetition is nothing more than identical identical forms that appear more than once in the design, that is to say, it would be a question of using the same element several times and distributed throughout the composition.

It is very important to resort to repetition especially when we are designing a graphic product that consists of several pages (catalog, magazine, etc.).

The repetition gives unity to the whole design, consistency and cohesion. Sometimes even on single page products, such as a diptych or triptych, it gives the feeling of continuity and that everything is "well tied". However, it should not be exceeded in its use. Repeating one or two graphic patterns is fine, but after three it would not be correct.
