Some students investigated the size of a population of dandelion plants in a field. The diagram below shows the field. The students: • placed a 1 m × 1 m square quadrat at 10 random positions in the field • counted the number of dandelion plants in each quadrat. The table below shows the students’ results. Estimate the total number of dandelion plants in the field. Calculate your answer using information from the diagram and the table above. Give your answer in standard form. Total number of dandelion plants – 7083

1. The mean number of dandelions per square meter is 6. The total field area is 55,000 m². To find the total number of dandelions in the field, multiply the mean by the area:
   6 × 55,000 = 330,000
   written in standard form as 3.3 × 10⁵.
