Answer:
A. 40%
Step-by-step explanation:
Model with an equation
50x = 20
Isolate x
x = 20/50
Simplify
x = 2/5
x = 0.4
Convert the decimal to a percentage (move decimal two places to the left)
0.4 = 40%
Step 1: Distribute
5x + 10 - 3x > 7 - 4x + 12
Step 2: Combine like terms
2x + 10 > -4x + 19
Step 3: Move all variable terms to one side, and all constants to the other
6x + 10 > 19
6x > 9
Step 4: Divide
x > 9 / 6
x > 1.5
Hope this helps!
Answer:
As in explanation.
Step-by-step explanation:
A) SSE means "Error Sum of Squares". The source of it is the sum of squared deviations within groups.
B) SSTR means "Treatment Sum of Squares". It's source is the weighted sum of squared deviations of group means from grand mean. It's the sum of squares between groups.
C) SST means "Total Sum of Squares''. It's source is total sum of squared deviations from the grand mean. It is a sum of SSE and SSTR.
Answer:
(x + 1)(x + 9) = 0
Step-by-step explanation:
After you subtract 16 from both sides, you get ...
x² +10x +9 = 0
When you factor this equation, it becomes ...
(x +1)(x +9) = 0
_____
For the zero product property to be of any use, the form of the equation must be a product that equals zero.
___
<em>Comment on the other answer choice</em>
(x -1)(x -9) = 0 = x² -10x +9 . . . . . the x term is different from that in the given equation. It has the wrong sign.
There is no picture to show me the graph. I am sorry
