Answer:
Step-by-step explanation:
5 red
3 blue
6 white
2 green
total 16 marbles.
Note: P(E) = probability of event E happening
P(~E) = probability of event E NOT happening.
We usually leave probabilities in fractions whenever possible because they will not be subject to round-off errors.
A. choose one marble at random.
P(W) = 6 white / 16 total = 3/8
B. choose one marble at random.
P(~R) = (16-5)/16 = 11/16
C. choose one marble at random, then a second one without replacement,
there will be 3 blue out of 16 at the beginning, then if successful, there will be 2 blue out of 15.
P(BB) = (3/16)*(2/15) = 1 / 40
D. choose two with replacement
5 red out of 16 for first draw, still 5 red out of 16 for second draw.
P(RR) = (5/16)^2 = 25/256
Hello!
The five-number summary is the lowest number, highest number, median, quartile 1 and quartile 3
First you should order the numbers from least to greatest.
65, 78, 80, 90, 92, 92, 98, 101,106, 112, 116, 119
The lowest number is 65
The highest number is 119
Next you can find the median
The median is the number in the middle
The two numbers in the middle are 92 and 98
Since there are two numbers you take the average
92 + 98 = 190
190/2 = 95
The median is 95
Now we know the answer is either A or B
Next you can find the lower quartile
The lower quartile is the median of the numbers under the median
So we list all the numbers under 95
65, 78, 80, 90, 92, 92
The numbers in the middle are 80 and 90
The average between these two is 85
So the lower quartile is 85
From this we know the answer is B
The answer is B
Hope this helps!

Answer:
x = 7, y = -5
Step-by-step explanation:
<u><em>Given~:</em></u>
<em>Solve the system below using elimination</em>
<em>{5x+9y= -10}</em>
