Answer:
a) tex] \bar X = \frac{\sum_{i=1}^n X_i}{n}[/tex]
And replacing we got:
b) 
And replacing we got:
Step-by-step explanation:
Part a
For this case we can calculate the the unweigthed with the following formula:
And replacing we got:
Part b
For this case the weigthed mena is given :
And replacing we got:
Answer:
Step-by-step explanation:
(-13u^6 x^6 + 4ux^6) / (-2u^2 x^5) can be rewritten as:
(-13u^6 x^6 + 4ux^6)
-------------------------------
(-2u^2 x^5)
Note that u is common to all terms here. Factoring out u, we get:
(u) [ (-13u^5)(x^6) + 4x^6 ]
--------------------------------------
(u) [-2u (x^5) ]
Reducing this leaves us with:
(-13u^5)(x^6) + 4x^6
--------------------------------------
[-2u (x^5)
Now note that x^5 is common to all terms here. Factoring out x^5, we get:
( -13u^5)(x) + 4x
-------------------------
-2u
This cannot be reduced further, since the 4x term has no u factor.
Do 3 times the length. Suppose the width is 12 centimeters, 3 times that is 36 centimeters plus 4 centimeters is 40 centimers so then you do 2w+2l
Answer:
2/15 cups of cheese
Step-by-step explanation:
Because you are eating 2/5 of the recipe you have to multiply the values
2/5*1/3 = 2/15
7x^2 + 3
7(4)^2 + 3
7(16) + 3
112 + 3
115.
