Answer: 311.5
Step-by-step explanation: 35*8.9=311.5
311.5/35=8.9
First, you have to find the median, which is the number in the middle: 25
Then cut the data in half by the median, so your new data sets are
15,29,20
and
31,38,41
Now you find the median of both of those sets, which is 29 and 38.
The interquartile range is the difference between the numbers, so 38-29 = 9.
5+10+10+12+14+7= 58
x= 70-58
x=12 ft
Answer:

Answer:
4.5 inches
Step-by-step explanation:
To find the height in inches of the model, you need to change the ration into a fraction:
Then try to figure out the value of the denominator in terms of the ratio:
In this equation we need to figure out how much the denominator of the fraction is changing by, by dividing 725 by 50. Then, multiply that by one:
