Answer:
P(X=0) = 0.7158
P(X=1) = 0.2684
P(X=2) =0.0158
Step-by-step explanation:
Number of defective laptops = 3
Number of normal laptops = 17
If the school chooses 2 laptops from this lot, the number of defectives (X) could be 0, 1, or 2.
For zero defectives:
For one defective:
For two defectives:
Answer:
y-intercept (0,1)
multiplicative rate of change: b
Step-by-step explanation:
If a table represents an exponential function of the form , then the y-value that corresponds to x=0 is 1.
In other words, the y-intercept (0,1) must be present in the table.
Also the ratio of a subsequent y-value to the previous y-value should give a value of b.
In other words the multiplicative rate of change from the table must be equal to b.
