Tnemos el sisema de ecuaciones:
Podemos resolverlo por eliminación sumando ambas ecuaciones y eliminando y. Asi podemos resolver para x:
Ahora podemos resolver para y con cualquiera de las dos ecuaciones:
Respuesta: x=-3, y=0
Explanation
Part A
We can use the formula below to find the mean.
We will then have;
Mean = 6.2632
Part B
Since the data set is odd.
Answer: From the column of cumulative frequency cf, the median is 7
Answer:
Please check the explanation!
Step-by-step explanation:
Given the equation
As some of the absolute rules are:
NOW, let us solve!
Let us substitute all the table values
Putting x = -4
∵
So, when x = -4, then y = -7
Putting x = -3
when x = -3, then y = -5
Putting x = -2
when x = -2, then y = -3
Putting x = -1
when x = -1, then y = -1
Putting x = 0
when x = 0, then y = -3
Putting x = 1
when x = 1, then y = -5

Yeah that seems good. ghg
Answer:
Step-by-step explanation:
Josh has a collection of 1,200 music CDs. He considers 1/6 of his collection rock music. This means that the number of rock music CDs that he has is
1/6 × 1200 = 200
Of the rock music CDs, 20 percent are by solo artist. This means that the number of CDs by solo artist is
20/100 × 200 = 40
Of the solo artist 2/5 are by female artist. It means that the number done by female solo artists is
2/5 × 40 = 16
