Answer:
P ( 1.2 < X < 2.1 ) = 0.3
Step-by-step explanation:
Given:
Uniform distribution over interval (0,3) can be modeled by a probability density function f(x)
f(x) = 1 / (b - a)
Where a < x < b is the domain at which function is defined:
f(x) = 1 / (3) = 1 / 3
Where, X - U ( u , δ )
u = ( a + b ) / 2 = (0 +3) / 2 = 1.5
δ = ( b - a ) / sqrt (12) = (3 - 0) / sqrt (12) = 0.866
Hence,
X - U ( 1.5 , 0.866 )
There-fore calculating P ( 1.2 < X < 2.1 ):

Where, a = 1.2 and b = 2.1
P ( 1.2 < X < 2.1 ) = x / 3 |
P ( 1.2 < X < 2.1 ) = 2.1 /3 - 1.2 / 3 = 0.3
Answer: P ( 1.2 < X < 2.1 ) = 0.3
First you must add up all of the numbers. Then divide the sum by the number of students in the class. You will get 2.65 as your answer. Then round to the nearest number. Your final answer is 3.
Answer:
1. Yes
2. No
Step-by-step explanation:
You can have a case such as 26,30,30,30,30 and another case : of 4,40,40,32,8 satisfying the 2 statements at the same time but in the 2nd case, the average that is less than 28.
From the given statements combined together, to get e-a=4. So once you get this information, you can have a big range of values that may or may not have average >28.
X=72 cause 180-(51+57) so 180-108 and the triangle is acute cause all of the angle measures are below 90 degrees.
So your answer is
x=72
Acute Triangle
