The radius is 2.5 all you had to do was divide 5 by 2 lol
Answer:
- <em>B) 41 − 45; 46 − 50; 51 − 55; 56 − 60 </em>
Explanation:
When you build a <em>histogram </em>the intervals must be of the same size. About 4 to 8 intervals is good but it also depends on the number of data and the range of those data.
Option D has only two intervals. That is too few. Thus, this is discarded. Three intervals also seems few. Thus, option C, is not good.
The option A shows intervals of different size:
- 46 - 41 = 4
- 49 - 46 = 3
- 52 - 49 = 3
- 56 - 53 = 3
Thus, this is not good either.
The optio B seems good:
Interval Frequency
- 45 - 41 = 4 3
- 50 - 46 = 4 4
- 55 - 51 = 4 4
- 60 - 56 = 4 1
Hence, the correct answer is B) 41 − 45; 46 − 50; 51 − 55; 56 − 60
Answer:
x(t) = –5 + 6t; y(t) = 3 – 9t
Step-by-step explanation:
In your graphing calculator, you can press 2nd then cos to create cos^-1 and then press 0.5967.
You’re basically doing arccos(0.5967) or cos^-1(0.5967)
Remember to put your calculator into radian mode first.
Your answer will be 0.9314138684 in radian
For degrees it would be 53.36608364
