Hey there! :)
In order to the find the missing side length of this triangle, we'll need to use the Pythagorean Theorem!
That equation is : a² + b² = c²
a = adjacent side
b = long side of rectangle
c = hypotenuse
We're already given the values of both a & c, so let's plug everything in!
a² + b² = c² → a = 10 , b = ? , c = 20
(10²) + b² = (20²)
Simplify.
100 + b² = 400
Subtract 100 from both sides.
b² = 400 - 100
Simplify.
b² = 300
Get the square root of b² & 300.
Simplify!
b = 17.3
So, the missing side length is the first answer choice : 17.3
~Hope I helped!~

Answer: 0.1797
Step-by-step explanation:
Given :
Let x be the random variable that represents BMI for adults in this country.
We assume that BMI for adults in this country is normally distributed.
Then, z-score for x=25.6 ,
Using z-value table , we have
The probability that the person's BMI is more than 25.6 :
Hence, the probability that the person's BMI is more than 25.6 = 0.1797
Hence, the probability that the person's BMI is more than 25.6 = 0.1796
Hence, the probability of the stick's weight being 2.23 oz or greater = 0.0174
