Answer:
3. 
Step-by-step explanation:
All the polynomials in the given option are quadratic.
By the fundamental theorem of algebra, the quadratic polynomial has two roots.
Since the solution set is given as {5}, the quadratic has a repeated root.
In other words the root has a multiplicity of 2.
Hence we have the equation:
, multiplicity 2
This implies that;
We expand to obtain;
The correct choice is the third option.
Answer: False
Step-by-step explanation: To find the mean time add all the times and divide by the amount of times you have, which is 9.
0 + 15 + 30 + 90 + 105 + 120 + 45 + 60 + 75 = 540 total minutes spent.
Now divide 540 by 9 to get the mean time. 540 divided by 9 = 60.
So the mean is 60 minutes, not 75 minutes.
Therefore the statement below is False.
The answer would be a.figure a
Answer:
About 30 if you want it really specific 29.3
Take 1,760 and divide by 60 which is 29.3
