The angle measures of any triangle = 180
adding 27 and 63. = 90
leaving 90 degrees for the remaining angle
therefore the triangle is a right triangle
by definition if a triangle has a 90 degree angle it's a right triangle
B is your answer if you need me to explain why just ask me :) have a good day
The experiment with the least number of trials.
Experimental probability is more accurate and more close to theoretical probability by having the most trials. More trials = more accuracy. Less trials = less accuracy.
Answer: 0.2643
Step-by-step explanation:
Given : The proportion of adults are unemployed : p=0.077
The sample size = 300
By suing normal approximation to the binomial , we have
Now, using formula 
, the z-value corresponding to 26 will be :-
Using standard distribution table for z , we have
P-value=
Hence, the probability that at least 26 in the sample are unemployed =0.2643
