Final answer:
Without the pictures, we cannot verify whether Yvette's statement about the ratio of triangles to hearts being 3:5 is correct. The correctness depends on the actual count of the shapes and correctly simplifying the ratio if necessary.
Step-by-step explanation:
The question presents a scenario where Yvette must determine the ratio of triangles to hearts. However, the actual pictures are not displayed here, so to give an accurate answer, it is assumed that one would count the number of triangles and the number of hearts and then form a ratio. The ratio of triangles to hearts is expressed as the number of triangles compared to the number of hearts, usually in simplest form.
If Yvette says the ratio is 3:5 but it was given as an alternative that the actual ratio could be 5:3 or 5:8, this implies a discrepancy in the counting or simplification process.
Without seeing the pictures, we cannot definitively say whether Yvette is correct or not. However, Yvette could be incorrect if she has miscounted the shapes or has not simplified the ratio correctly
