The graph of this parabola is shown below. From this graph we know that:
VERTEX:
DIRECTIX:
Since the vertex lies on the origin and the parabola opens upward, then the standard form of this parabola is:
So:
Then the directrix is:
Answer: Its simple! (2)
Step-by-step explanation:
We found the factors and prime factorization of 8 and 6. The biggest common factor number is the GCF number. So the greatest common factor 8 and 6 is 2.
Answer:
Step-by-step explanation:
from the question,
the mean 14
the standard deviation is 3
and sample size is 10.
since the n which is the sample size is 10, then the distribution is mound shaped.
why?
this is due to the fact that the random variable from which we took the sample is mound shaped.
The sampling distribution of the mean is normally distributed although the question says the random variable is not normally distributed. so the shape is bell shaped and normally distributed.
the standard deviation of the mean is
3/√10
= 0.948
Answer:
169
Step-by-step explanation:
divided = divisior * quotient + remainder
so d = 13*13
= 169
