Answer:
The probability of selecting two democrats is 1/380
Step-by-step explanation:
- Probability is the branch of mathematics that deals with numerical descriptions of how likely an event is to occur.
- Probability of an event = Number of favourable outcomes / Total number of outcomes.
Here we are given the people as,
8 democrats, 8 republicans and 6 independent.
So total number of people are: 8+6+6=20
Probability of choosing first democrat = 1/20
Probability of choosing first democrat = 1/19
Thus P( two democrats in succession ) = 1/20 ×1/19
= 1/380

In the way you asked the question, the answer is already there but I am going to assume u are asking how many bracelets you can make which would then put the answer at almost 9 bracelets.
The best answer is C) y=4.75 * cos(0.52x - 2.08) + 7.65
Unfortunately, the two only ways to solve this problem are to either graph all the options or plug in time values for x and see which agrees the most with the tide chart. Both are time-consuming, but I chose to graph each one with a graphing application.
Plugging in a few values for x confirms that C is the best function.
12pm (x=0)
y = 4.75 * cos(0 - 2.08) + 7.65
y = 5.334
2pm (x=2)
y= 6.5
4pm (x=4)
y=12.4
It is not a perfect representation, but the shape of the graph and closeness to the points given is the best of the four options provided.
