PLEASE HELP! I WILL GIVE BRAINLIEST!!!! (no trolls) PLEASE SHOW WORK OR GIVE EXPLANATION!!!!!!
IgorLugansk [536]

explanation:

The fastest way to find the missing endpoint is to determine the distance from the known endpoint to the midpoint and then performing the same transformation on the midpoint.  In this case, the x-coordinate moves from 4 to 2, or down by 2, so the new x-coordinate must be 2-2 = 0.  The y-coordinate moves from 4 to -5, or down by 9, so the new y-coordinate must be -5-9 = -14.

 

An alternate solution would be to substitute (4,4) for (x1,y1) and (2,-5) for (x,y) into the midpoint formula:

x=(x1+x2)/2

y=(y1+y2)/2

Solving each equation for (x2,y2) yields the solution (0,-14).

The probability that a lab specimen contains high levels of contamination is 0.15. A group of 4 independent samples are checked.
Lady bird [3.3K]

Answer:

0.5220

Step-by-step explanation:

Since the probability of contamination is 0.15, the probability of no contamination is 1 - 0.15 = 0.85

The probability that they are all contaminated will be 0.85 * 0.85 0.85 * 0.85 = 0.52200625

This is 0.5220 to four decimal
