Make a number line and draw the 5 points if the five Dots
Answer:
answer is 2/6
becoz 2/6=0.3333333333 which is repeating or recurring decimal
Step-by-step explanation:
You need to see what factors can divide into both problems
By Pythagoras AB^2 = 12^2 - 6^2 = 108
AB = sqrt 108 = 10.39 to nearest hundredth
The perpendicular from M to DC will be parallel and equal to AB so it = 10.39.
Also AB^2 = CB * DB
108 = 6 * DB
DB = 108/6 = 18
so DC = 18-6 = 12
MD^2 = (1/2*12)^2 + 108 = 144
so MD = 12
Point estimate is the method of looking for an approximate value of some parameter - example: the mean (average) and it could be also the sample standard deviation of a population from random samples of the population.
To get the point estimate: 20 (people wearing hearing aids) / 304 (total random sample) = 0.0657894 or 0.066
