Answer:
Can't answer this
Step-by-step explanation:
For this question, I think you need to read more informations, find out the function
After you find out the function,
Replace f(x) as 12 and replace x with n
After that, try to solve it.
Good luck.
Answer:
C. The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
Step-by-step explanation:
If data is normally distributed we use Standard deviation otherwise we use Interquartile Range (IQR) for measuring the spread.
Further, data is said to be normally distributed if Mean = Median = Mode.
So, High School data is normally distributed but College data is not.
So, We measure the spread of College data by IQR and High School data by Standard Deviation.
Thus, Option C is the only correct option.
Step-by-step explanation:
y = 4x²+ 40x+112 (:4)
x²+ 10x+ 28.
<u>28</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>
1. |. 28
2. |. 14
4. |. 7
(x+4)(x+7)=0
x= -4. V. x= -7
Now fill in the x= -4 in y so you get the Y-coordinate and do the same for x= -7
Anseer should be like: 'The coordinates are (x, y) and (x, y)
Y=.25x +700 ; 200 miles
I think the inequality is right
Answer:
<h2>
</h2>
Step-by-step explanation:
f(x) = x - 5
g(x) = 3x² - 1
To find (fºg)(x) substitute g(x) into f(x) that's for every x in f (x) replace it with g (x)
That's

We have the final answer as
