Answer:

A. Determine the average number of leaves for 10 randomly selected maple trees.

Step-by-step explanation:

By randomizing and selecting 10 trees you can have a very close estimate on how many leaves there are per tree in the whole forest in a relatively little amount of time, this can help the scientists advance easier with their study rather than sending a team to count every single leaf in the forests and they dividing it by the number of trees.

Answer:

  (6, 2), (0, -2), (-3, -4)

Step-by-step explanation:

The intercepts are clearly (0, -2) and (3, 0). This eliminates the bottom two choices.

Both of these are listed in the upper left choice, but the third point there, (-6, -5), is not on the graph. This leaves only the upper right choice. Checking the remaining two points in that choice, (6, 2) and (-3, -4), confirms they are both on the graph.

Lisa sold 11 shirts for every 7 shirts Becky sold. If the girls sold 72 shirts in all, how many shirts did Becky sell?
Eva8 [605]

Answer: 28 shirts

Step-by-step explanation:

From the question, we are informed that Lisa sold 11 shirts for every 7 shirts Becky sold. This can be expressed in a fraction as:

Lisa = 11/(11 + 7) = 11/18

Becky = 7/(11 + 7) = 7/18

If the girls sold 72 shirts in all, the number of shirts sold by Becky will be:

= 7/18 × 72

= 7 × 4

= 28
