<span> D) Train A by a factor of 1.1
</span>Train A: <span>17/35</span><span> = 34.6</span>
<span>Train B: </span>Rate<span> is the </span>slope<span> of the </span>equation, 31.35
Thus,<span>34.6/31.35</span><span> = 1.1036</span>
The mean is 20.7
<h3>What is Mean?</h3>
Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.
Class Frequency{f} Midpoint of frequency{x} fx
1-7 13 4 72
8-10 14 9 126
11-15 18 13 234
16-20 6 18 108
21-35 13 28 364
36-50 19 43 817
Sum 83 1721

Answer:
The tree is 28 feet in height.
Step-by-step explanation:
This is a proportion problem. You need to keep the height of the objects on one side of the ratios and the length of the shadows on the other.
74 / x = 102/39 Cross Multiply
102x = 74*39 The inches as a unit cancel out.
102x = 2886 Divide by 102
x = 2886/102
x = 28.29 feet
All probability chances equal 1.
So, subtract 1 and 7/11 to get your answer
The answer is 4/11.
