Based on the construction, the length of the bridge deck is given by r = √(x² + y²) units.
<h3>What is a deck?</h3>A deck is also referred to as the roadway and it can be defined as the functional area which is designed and developed to allow automobile vehicles and pedestrians to cross highways, valleys, and water bodies.
In order to determine the length of the bridge deck, we would apply Pythagorean's theorem as follows:
r² = x² + y²
<u>Where:</u>
- r is the length of the bridge deck.
- a is the adjacent side (horizontal distance).
- b is the opposite side (rise of the bridge).
Making r the subject of formula, we have:
r = √(x² + y²)

Answer:
0.67038
Explanation:
One z-value is negative and the other is positive.
This means we are looking for area between the two given z-values on opposite sides of the mean.
From z-table attached, the area at z = -2.31 is 0.98956
Also, from the second z-table attached, the area at z = 0.47 is 0.68082
But since we are looking for the area between both z-scores, we will now have;
P(-2.31 < x < 0.47) = (0.98956 + 0.68082) - 1
P(-2.31 < x < 0.47) = 0.67038
