Answer:
<h2>C</h2>
Step-by-step explanation:
using the pythagorian theorem, we know that a^2+b^2=c^2. inputting the numbers into this equation, we get
8^2+23^2=c^2
then, using our big math brains, we get 64+529=c^2
adding together the numbers, we end up with 593
just take the sqyare root of that and bada bing bada boom! you get 24.35, or 24.4, therefore the answer is C

Answer:
D. The students are not part of the population
Step-by-step explanation:
The first three options are true of this sample. D is the only option that is not true.
Let x and y be the 2 parts of 15 ==> x + y=15 (given)
Reciprocal of x and y ==> 1/x +1/y ==> 1/x + 1/y = 3/10 (given)
Let's solve 1/x + 1/y = 3/10 . Common denominator = 10.x.y (reduce to same denominator)
==> (10y+10x)/10xy = 3xy/10xy ==> 10x+10y =3xy
But x+y = 15 , then 10x+10y =150 ==> 150=3xy and xy = 50
Now we have the sum S of the 2 parts that is S = 15 and
their Product = xy =50
Let's use the quadratic equation for S and P==> X² -SX +P =0
Or X² - 15X + 50=0, Solve for X & you will find:
The 1st part of 15 is 10 & the 2nd part is 5
