Answer:
The highest value of X that is consistent with the belief that the tree died due to natural causes is:
1.5
Step-by-step explanation:
a) Data and Calculations:
Proportion of trees planted last year that died within a month = 1/10 or 10% (1/10 * 100)
Number of new trees planted by a new landscaping firm = 15
Let X = number of trees planted (out of 15) that died
Since it is believed that the earlier trees died out of natural causes,
Therefore, X = 10% of 15
= 1.5
The associative property has been used in step 3
Step-by-step explanation:
There are multiple properties that are used to solve the equations
One of them is associative property.
Associative property states that the order of three terms which are being added doesn't matter the result will be same.
![a + (b+c) = (a+b)+c](https://tex.z-dn.net/?f=a%20%2B%20%28b%2Bc%29%20%3D%20%28a%2Bb%29%2Bc)
In step 2:
![2 + 2x + 10 + (-10 + 11x)](https://tex.z-dn.net/?f=2%20%2B%202x%20%2B%2010%20%2B%20%28-10%20%2B%2011x%29)
As we can see that the last three terms are being added
The solver has used the associative property to solve the expression.
![2 + 2x + [10 + (-10)] + 11x](https://tex.z-dn.net/?f=2%20%2B%202x%20%2B%20%5B10%20%2B%20%28-10%29%5D%20%2B%2011x)
The brackets have been changed from
using associative property
The associative property has been used in step 3

For each of the problems, twice the angle formed by the chords is equal to half the sum of the angles of the arcs.
So, for the first problem, we have
![94 \cdot 2 = x+103](https://tex.z-dn.net/?f=94%20%5Ccdot%202%20%3D%20x%2B103)
, so
![x = 188 - 103 = 85](https://tex.z-dn.net/?f=x%20%3D%20188%20-%20103%20%3D%2085)
.
For the second,
![102 \cdot 2 = x + 118](https://tex.z-dn.net/?f=102%20%5Ccdot%202%20%3D%20x%20%2B%20118)
, so
![x = 204 - 118 = 86](https://tex.z-dn.net/?f=x%20%3D%20204%20-%20118%20%3D%2086)
.
For the last problem,
![106 \cdot 2 = x + 88](https://tex.z-dn.net/?f=106%20%5Ccdot%202%20%3D%20x%20%2B%2088)
, so
![x = 212 - 88 = 124](https://tex.z-dn.net/?f=x%20%3D%20212%20-%2088%20%3D%20124)
.

Answer:
£72
Step-by-step explanation:
Firstly, if half of 96 coins are £1 coins then:
96/2 * 1 = value of half the coins = £48
Now, we simply need to multiply 96/2 by 0.5 to find the value of these coins:
48 * 0.5 = 24
Now we can add the two:
48 + 24 = 72
So the value of the 96 coins are £72.
