Step-by-step explanation:
Answer:
The relationship between the two is that they are equal.
Step-by-step explanation:
Since y = cosx is a even function, that means that cosx = cos(-x). Therefore, cos 90 degrees = cos -90 degrees.
We can also test this out:
cos 90 = 0
cos -90 = cos 270 = 0
Therefore, this came to the same conclusion as our first solution.
I hope this helps! :)
5 milk choc and 8 dark choc....total of 13 chocolates
P(1st pick is milk choc) = 5/13
do not replace
P(2nd pick is milk choc) = 4/12 which reduces to 1/3
P(both picks are milk choc) = 5/13 * 1/3 = 5/39 <== or 12.8%
100/2 = 50 pies per hour
350/50 = 7 hours
