Lady bird [3.3K]

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%

Help!!!!
ipn [44]

Answer:

The answer to your question is: letter A

Step-by-step explanation:

See the picture below

When we divide the polynomial by the factor the result is zero, that's why letter A is the factor.

When we divide the polynomial by B, C or D the residue is not zero, then they are not factors.
