Answer:
population parameter
Step-by-step explanation:
A population is said to be category of individuals under study.
A population parameter is a numerical value which provides a summary to a measure of an average or percentage which describes the entire population under a study.
In a Normal Curve, the population parameter can be a population mean or population standard deviation , population proportion which represent the population.
∴
The average SAT score of 1356 in the given study is a population parameter
Answer:
Step-by-step explanation:
The answer is 4.
Once you add 4, you get:
x^2 -2x + 4 = 7.
The left side is factorable:
(x-2)^2 = 7.
There is your perfect square.
Answer:
since the unknown amount can buy 100 pencils
he bought 70 pencils
therefore $4.50 can buy 30 pencils
so 1 pencils cost $4.50 /30=0.15

Step-by-step explanation:
This question requires a list of options.
Since, there are none; I'll give a general explanation to answer this.
We have that:
The general format of an equation in terms of f and c is:
Where
and
A true statement about the function above is:
The slope of the equation is 14
This means that at every minute, there's an additional 14 chirps from the cricket.
Another true statement about the function is that:
The y intercept is 40.
This means that the initial number of chirps by the cricket is 40
i.e. At time, c = 0 minutes.
There are 40 chirps.
A likely question could be to determine the number of chirps in (say) 5 minutes.
This means that:
Substitute 5 for c in
This implies there are 110 chirps in 5 minutes
