Addictive property Becayse it’s adding and it’s using that type of property. D
Answer:
11x -8y = -9
Step-by-step explanation:
8x-4y=-4
-3x+4y=5
Subtract the second equation from the first
8x-4y=-4
-(-3x+4y=5)
-----------------------------
Distribute the minus sign
8x-4y=-4
+(3x-4y=-5)
-----------------------------
11x -8y = -9
Answer/Step-by-step explanation:
A. The cluster is where the 100 is to the 235. The outlier is 1,110 cause it is way out in the open alone almost 300 numbers away from its nearest number
B. For the correlation if you notice how it goes from 200... > 400...> 600...>800...it kinda like a pattern of adding 200
C. The independent variable is temperature and the dependent is sales. since the amount of money made depends on the temperature.
Answer:
The larger number is 60
The smaller number is 14
Explanation:
Assume that the larger number is x and that the smaller number id y.
We are given that:
1- The sum of the two numbers is 74. This means that:
x + y = 74
This equation can be rewritten as:
x = 74 - y .............> I
2- Four times the smaller number (4y) subtracted from the larger number (x), the result would be 4. This means that:
x - 4y = 4 ..............> II
Substitute with I in II and solve for y as follows:
x - 4y = 4
74 - y - 4y = 4
74 - 5y = 4
5y = 70
y = 70/5
y = 14
Substitute with the value of y in equation I to get x as follows:
x = 74 - y
x = 74 - 14
x = 60
Hope this helps :)
The mean is the average. Add all the numbers together, then divide by the quantity of numbers in the data set.
1040 / 13 = 80
The mean is 80
