Sophia's steps to evaluate the expression on
- 9 ÷ 9 when n = 3 are shown below.
gn
- 9 ÷ 9 when n = 3
9 × 3 = 27
27
- 9 = 18
18 ÷ 9 = 2
What should Sophia have done differently to evaluate the
expression correctly?
A
subtracted 9 from (27 ÷ 9)
B
subtracted (9 ÷ 9) from 27
C
divided
(27
9) by
(27 - 9)
) D
divided (27 - 9) by (27 × 9)

Find the x coordinate of the point.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

The american academy of pediatrics wants to conduct a survey of recently graduated family practitioners to assess why they did not choose pediatrics for their specialization. provide a definition of the population, suggest a sampling frame, and indicate the appropriate sampling unit.
