The centers for disease control and prevention reports that 25% of baby boys 6-8 months old in the united states weigh more than 20 pounds. a sample of 16 babies is studied. what is the probability that more than 6 weigh more than 20 pounds?

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.
