Answer:
Well the slope would be 0 because the y doesn't change. So if y is same it is 0, if x remains the same Slope is undefined, and then there is normal slope.
Step-by-step explanation:
Answer:
about 8.8×10⁻⁵
Step-by-step explanation:
This probability is best found using a probability calculator of some sort. The z-score is ...
... (464-479)/4 = -3.75
You will have to search a bit to find a probability table that lists probability values for z-scores beyond ±3.00.
Answer:
the common difference is plus 3
Answer:

Step-by-step explanation:

Which is a trinomial and has a constant term
The highest degree of a trinomial is 2;
So, (b) and (d) are trinomial.
However, (b) has a constant term of -7 alongside the trinomial
while (d) has a constant term and also have a term with coefficient of x
Hence, (b) is correct
