A quadrilateral which could be used to show that Ron's claim is false is a trapezoid.
<h3>What is a
quadrilateral?</h3>
A quadrilateral can be defined as a type of polygon that has four (4) sides, four (4) vertices, four (4) edges and four (4) angles.
<h3>The types of
quadrilateral.</h3>
In Geometry, there are different types of quadrilateral and these include the following:
Generally, the opposite sides of a trapezium is not congruent unlike the other quadrilaterals. Thus, a quadrilateral which could be used to show that Ron's claim is false is a trapezoid.

Answer:
The answer is 0.9599.
Explanation:
mu (sample) = mu = 8.4
s.d. (sample) = 1.8/ sq. rt. 40
P( greater than 8.1) = (8.9-8.4)/(1.8/ sq. rt. 40)
Let x be the mean time for the 40 mechanics
Standardize the mechanics: (8.9-8.4)/(1.8/ sq. rt. 40) = 1.75 = Z
P( x > 8.9) = P(Z > 1.75), this means the area to the right of Z = 1.75.
Then you need to look in the table of the Normal distribution, Z(1.75) =0.9599
