Given that t<span>he
mean lifespan of a sylvania light bulb is 1600 hours with a standard
deviation of 300 hours, an iqr of 450 hours, and a range of 690 hours.
the lifespan distribution is relatively symmetric.
Since, the distribution is relatively symmetric, the measure of
spread that is the best measurement is the standard deviation.</span>

Answer:

Step-by-step explanation:
If P partitions AB in the ratio 1:1, it means AP = ½ of AB, and PB = ½ of AB.
Therefore, P can be said to be a midpoint between A and B.
To find the coordinates of P, use the midpoint formula:
Midpoint (P) of AB, for A(3, 5) and B(1, 2) is given as:

Let 

Plug the values into the formula:



32 x 15= 480
20 x 14= 280
480 + 280= 760
They will need 760 squared feet worth of sod
