Answer:


Step-by-step explanation:
We know that ,
Null hypothesis
is a statement that contains the population parameter to represent claim or against claim statement along with = , ≤ and ≥ signs.
Where as Alternative hypothesis
is also a statement that contains the population parameter but against the null hypothesis . It contains ≠ , < and > signs.
In the given situation, the population parameter is population mean
.
Claim: The mean pulse rate (in beats per minute, or bpm) of adult males is equal to 69 bpm.
i.e. 
and
[Against
]
5 hours
715/11 = 65
325/65 = 5
Answer:
I thin B -7 cause its negative and negative goes down.
Step-by-step explanation:
Hello there.
To answer this question, we need to remember some properties about the vertex of quadratic functions.
Let
. Its vertex can be found on the coordinates
such that
and
, in which
.
Using the coefficients given by the question, we get that:

Thus, we have:

So the statement is true, because the
coordinate of the vertex of the function is equal to 

\oint is what you're looking for
