It’d be 12.458 , rounded to the nearest tenth makes it 12.5. Hopefully, I helped.
Answer:
Option D) The data are continuous because the data can take on any value in an interval
Step-by-step explanation:
We are given the following in the question:
Data: The heights (in feet) of different buildings
Discrete and continuous data:
- Discrete data is the data that cannot take values in decimals and continuous data can take values in decimals.
- Continuous data can take any value within an interval.
- Discrete data cannot take all the value within an interval.
- Discrete data is counted where as continuous data is measured.
Thus, height is a continuous data since it can take any values within an interval and is measured.
Thus, the correct answer is
Option D) The data are continuous because the data can take on any value in an interval

Answer:
306
Step-by-step explanation:
6*9=54
54*4=216
216+90=306
<span>Think of arcsin (-1/3) as an angle, and call it "theta." The the original problem becomes "find sec [ 2 theta ]"
1 1
which is the same as "find ------------------ " or --------------------------------------
cos[2 theta] (cos theta)^2 - (sin theta)^2
Recall that theta = the angle whose sine is -1/3. Thus, sin theta = -1/3 and cos theta = 2sqrt(2) / 3.
So we now have:
1
-------------------------------------------
2 sqrt(2) -1
[------------------- ]^ 2 - [ ------- ]^2
3 3
which boils down to:
1 1
----------------- = ---------------- = 9/7 (answer)
8 1 7/9
------ - --------
9 9
