a special 8-sided die is marked with the numbers 1 to 8. it is rolled 20 times with these outcomes:
3 4 5 2 7 1 3 7 2 6 2 1 7 3 6 1 8 3 5 6

the experimental probability of rolling an odd number is
%, which is
% more than the theoretical probability.

The experimental probability of rolling an odd number is  

55%, which is  

5% more than the theoretical probability.

Step-by-step explanation:

3 4 5 2 7 1 3 7 2 6 2 1 7 3 6 1 8 3 5 6

The odd outcomes are in bold below:

3 4 5 2 7 1 3 7 2 6 2 1 7 3 6 1 8 3 5 6

There were 20 rolls of the die. 11 of the 20 rolls were odd.

experimental probability of rolling an odd number = 11/20 = 55%

The die has 4 even numbers and 4 odd numbers. The theoretical probability of rolling an odd number is

theoretical probability of rolling an odd number = 4/8 = 1/2 = 50%

The experimental probability is 5% more than the theoretical probability.

The experimental probability of rolling an odd number is  

55%, which is  

5% more than the theoretical probability.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
