Answer:
Find the hypotenuse of the triangle on the bottom:
a^2+b^2=c^2
6^2+8^2=10
then use x=square root of a2+b2 to find side x
x=6.63
Step-by-step explanation:
C. ABCD is a trapezoid, but it is not an isosceles trapezoid.
Step-by-step explanation:
ABCD is a trapezoid not an isosceles trapezoid. Because opposite sides of isosceles trapezoid are parallel.
The characteristics of trapezoid are legs, lower base angles, upper base angles diagonals are congruent.
The characteristics of isosceles trapezoid are bases are parallel, opposite sides are same length.
From the above mentioned characteristics of an Trapezoid and Isosceles trapezoid the given is trapezoid.
Given data clearly mentioned in diagram ABCD, where a≠b, a≠0 and b≠0 So, it is trapezoid.
Result:
So, the given is Trapezoid not an isosceles trapezoid . Because ABCD, where a≠b, a≠0 and b≠0.
The answer is A. 0.0000805

The percentage of runners that have times less than 14.4 seconds that is P(x<14.4) is 0.0013499 which is approximately = 0.15%.
<h2>What is standard deviation?</h2>
The standard deviation of a data set is defined as how the data is dispersed in relation to the mean.
From the question,
The raw time given (X) = 14.4 sec
The mean value(m) = 18sec
The standard deviation(d) = 1.2 sec
Using the formula,
z = X - m/ d
z= 14.4- 18/1.2
z = -3.6/1.2
z= -3
Using a Z table to find the percentage equivalent of P(x<14.4) is 0.0013499 which is approximately = 0.15%.
Therefore, the percentage of runners that have times less than 14.4 seconds that is P(x<14.4) is 0.0013499 which is approximately = 0.15%.
