Allan planted several marigold seeds in his garden and several weeks later, measured and recorded the height (in centimeters) of each plant. The histogram below shows his data. Of those planted, how many marigolds are between 4.0 and 6.9 cm. tall?

5

Step-by-step explanation:

The number of marigolds planted in each range of heights is represented by the frequency that is attached to the bar.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
