A <em>parent function</em> is the simplest function of a family of functions. What this means is that there is typically only <em>one operation</em> being performed in this particular function, and no other modifications or transformations are being performed on it. Which of those functions only contain <em>one operation</em>?
Answer:
Tyler grouped up 6-2 and 5-4 instead of grouping up the x terms.
6-2x + 5+4x=
2x+4x= ?
6 + 5 = 11
11- 2x + 4x =
-2x + 4x = 2x
2x + 11
Step-by-step explanation:
Y=amount of money paid. (in $)
x=number of songs download.
We have this function:
y=0.25x+9.99
Then:
if y=113.74
113.74=0.25x+9.99
0.25x=113.74-9.99
0.25x=103.75
x=103.75 / 0.25
x=415
Answer: the number of songs downloaded would be 415.
Answer:
(0.6613, 8.3387)
Step-by-step explanation:
Let the heights of men be the first population and the heights of women be the second population. Then
We have 
, 
, 
and
, 
, 
. The pooled
estimate is given by
The 99% confidence interval for the true mean difference between the mean height of the men and the mean height of the women is given by (if the samples are independent)
, i.e.,
where 
is the 0.5th quantile of the t distribution with (15+7-2) = 20 degrees of freedom. So
, i.e.,
(0.6613, 8.3387)
X- intercepts is when x equals 0 and y- intercepts is when y equals 0. So, if the x is the time and the y is the height, the coordinates for the x- intercept is (0,3), and the y- intercept (7,0)
