Given:
4 rows of ten students.
Probability of a head or tail in a coin toss is 1/2
head: 20 students sitting in the first two rows as your sample
1/2 * 1/20 = 1/40
tail: 20 students sitting in the last two rows as your sample.
1/2 * 1/20 = 1/40
<span>Does every student have an equal chance of being selected for the sample?
</span>
Yes, every student have an equal chance of beings elected for the sample.
The domain and range of
the function f(t)=sec[((pi)t)/4] are the following:
<span>Domain: All the real
numbers except t = 2 + 4k, where k is an integer. </span>
Range: (-∞, -1] U
[1, ∞)
I am hoping that these answers
have satisfied your queries and it will be able to help you in your endeavors, and
if you would like, feel free to ask another question.
Answer:
B) 68.91 inches
Step-by-step explanation:
To start, lets define what we are trying to find. VYX is the major arc VX, spanning from V to X crossing over Y.
We are also given that the diameter is 28 inches.
Since arc length and area are proportional to the central angle, we can create the following equality:
angle of VYX/360 = arc length of VYX/circumference
We know that the central angle of VYX = central angle of minor UV + UYX = 117 + (180-15) = 282 degrees.
282/360 * 28*pi = arc length of VYX
Thus, the length of VYX = 68.90559887 inches
Thus, the correct answer is B, 68.91 in.
