Consider a political discussion group of 8 democrats, 8 republicans and 6 independent suppose the teo groups meme bet are random
BartSMP [9]

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

The depths of water, at the edge of a pier, at different times of day, are represented by the table below. Which of the followin
s344n2d4d5 [400]
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.
