Julio is running a 13.1 mile race there are water stops every 2.75 miles along the route from the beginning of the race. What is

Gemiola [76]

If you divide 13.1 by 2.75 you'll get 4 plus a remainder so we know there are 4 stops at 2.75 intervals. 4*2.75=11. Subtract 11 from 13.1 and the last stretch would be 2.1 miles.
I hope this helped!

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -3.75)

Point (-1, 4.5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$

vladimir1956 [14]

If $X$ is a random variable representing test scores, then the 41st percentile is the score $x$ such that $P(X\le x)=0.41$ . Transform $X$ to the random variable $Z$ that follows the standard normal distribution via $X=31.5+7.3Z$ :
