16 because 25% of 20 is 4 so 4 question were choice B. Then, I subtracted 20 by 4 and got 16. I hope that helped! :)
Answer:
Graph B
Step-by-step explanation:
we know that
The graph that represent the situation
As x increases, y increases
Is the graph B or the graph C
but
Graph B represent a moderate coefficient of correlation r (-0.5 to -0.3 or 0.3 to 0.5)
Graph C represent a strong coefficient of correlation r (-1.0 to -0.5 or 1.0 to 0.5)
In this problem we have r=0.42
so
The coefficient of correlation is Moderate
therefore
The answer is the Graph B
Answer:
A. √16
Step-by-step explanation:
A perfect square is any number that can be expressed as a product of an integer and itself. i.e. 4 can be represented as 2 × 2. Therefore, 4 is a perfect square.
From the options given, the only radical expression that has two perfect square is √16.
√16 consists of two perfect squares, which are 4 and 4.
4 can be expressed as 2 × 2.
Thus: √16 = √(2 × 2)(2 × 2).
Therefore, √16 consists of two perfect squares.
You need to solve for x (get x by itself)
x - 18 = -5 Add 18 on both sides
x - 18 + 18 = -5 + 18
x = 13
A. It falls to the left and falls to the right and has an axis symmetry at x= -5
