The corresponding sides of the model and the actual bridge are in proportion because the two solids are similar.
The scale factor from the model to the actual bridge is 5/25 = 6/30 = 8/40 = 1/5.
Answer: 1/5
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!
Well to solve these type of question it is very easy to make a tree diagram and then solve them. How ever i have done it here for you.
So basically we have to get a pen from the first box so its probability is 7 / 10.
Similarly, we have to get a crayon from the second box so its probability is 2 / 8.
Now by counting principle we can multiply the two probabilities so 7/10 * 1/4 which becomes equal to 7/40.
Answer:
-20/-8
