Answer: the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
Step-by-step explanation:
Given data;
lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min
hence, height = 1 / ( 52.0 - 50.0) = 1 / 2
now the probability that the class length is between 50.8 and 51 min = ?
P( 50.8 < X < 51 ) = base × height
= ( 51 - 50.8) × 1/2
= 0.2 × 0.5
= 0.1 ≈ 10%
therefore the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
Answer:
Answer: The statements are numbers 1, 3, 4
The non statements are 2, 5, 6
Step-by-step explanation:
(20*30)/2 = 300
300 km is the area of the triangle
Answer:
D) 2
Step-by-step explanation:
A Triangle two sides added together must always be greater than the other side.
It can not be 2 because the two sides of a triangle added are not greater than the other side.
Here 5 + 2 = 7 which is not greater than 7 on the other side, so 2 fails.
Answer:
If x + 1 is odd, then x is even.
Step-by-step explanation:
The converse of the statement ...
if P, then Q.
is ...
if Q, then P.
Here, we have P="x is even" and Q="x+1 is odd". The converse statement is ...
if x+1 is odd, then x is even.
