Answer:
(C) 0.27 × 9 = 2.43
Step-by-step explanation:
Each colored section is 27 small squares, so is 27/100 = 0.27 of the whole. There are 9 colored sections, together totalling 2 wholes plus 43 small squares, or 2.43.
The equation this represents could be ...
0.27 × 9 = 2.43 . . . . . matches choice C

The theoretical probability is what is expected based on using math. Since there is only one card that is number 1, and there are 400 possible outcomes, then the theoretical probability is 1/400 which is 0.25%.
Now find the experimental probability by find the number of times card 1 is picked, and the number of cards in total. 128/400 = 0.32 which is 32 percent.
The experimental probability is higher than the theoretical probability.
Hope this helps
Factor a square root of 14 out of every expression to get:
Thus, the expression is equal to four times the square-root of 14. The second answer is correct.
