Step-by-step explanation:
Answer:
There are total 12 outfit combinations.
Step-by-step explanation:
Number of hat are: 2
1 red hat and 1 black hat
Number of shirt are: 3
1 white shirt , 1 black shirt , 1 black-and-white striped shirt.
Number of pants are: 2
1 black and 1 blue
Now, the total number of combinations could be seen with the help of a tree diagram.
We observe that total 12 combinations are possible.
If it's parallel to that equation, then that means the slope must be the same
Using the equation they gave us, we find the slope:
3+4x=2y-9
12+4x=2y
y=2x+6 (I just rearranged it after dividing both sides by 2)
Therefore, the slope of the equation is 2
So y=2x+b
Then they gave us the point (4,-4) and we can use that to find the intercept by plugging the values in for x and y:
-4=2(4)+b
-4=8+b
b=-12
So the equation is y=2x-12
Answer:
A) It is 8 below the mean.
Step-by-step explanation:
Let x be the mean
Value 1 is x+3
Value 2 = x+4
Value 3 = x+1
Value 4 = y
The means is found by adding all the values together and dividing by the number of values
Mean = (Value 1 + value 2 + value 3 + value 4 )/4
x = (x+3 + x+4+x+1 + y)/4
Multiply each side by 4
4x = (x+3 + x+4+x+1 + y)
Combine like terms
4x = 3x +8 + y
Subtract 3x from each side
4x-3x =3x-3x y+8
x = y+8
Subtract 8 from each side
x-8 = y+8-8
x-8 =y
The 4th number is 8 below the mean since x is the mean
