A manufacturer tests a certain number of headsets that are produced each day. There is a 2% chance of finding a defective headset. If 280 units of that model are tested, the manufacturer would expect to find approximately how many head sets without any defects

Correct headsets= 274.4 = 274

Step-by-step explanation:

Giving the following information:

Number of units= 280

There is a 2% chance of finding a defective headset.

To calculate the number of headsets without any defect, we need to use the following formula:

Correct headsets= 280*0.98

Correct headsets= 274.4 = 274

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
