Answer:
b
Step-by-step explanation:
The top vertex of the triangle on the right is 51° ( alternate angle to 51°
The sum of the 3 angles in a triangle = 180° thus
51 + 72 + y - 6 = 180 , that is
y + 117 = 180 ( subtract 117 from both sides )
y = 63 , then
y - 6 = 63 - 6 = 57
------------------------------
x - 5 , 51 and y - 6 lie on a straight line , therefore
x - 5 + 51 + y - 6 = 180
x - 5 + 51 + 57 = 180
x + 103 = 180 ( subtract 103 from both sides )
x = 77
Thus x = 77 , y = 63 → b
You need to use a diagram at least if your a beginner
The answer would be 10 because anything under 4 rounds down (including 4 itself, unlike 5, which rounds up.
Answer:
Easy! The cool thing about correlations is you can easily determine them by reading your graph, no hard brain work involved!
It should be A.
Step-by-step explanation:
By looking at the graph, you can already determine that the correlation is negative, since it's going down, not up.
Now, you need to read what is happening on the graph. As the price (X-Axis) is increasing, less people are spending their money, presumably because it's not priced affordably. So as you can see according to your Y-Axis, the amount of people buying is lowered.
Hopefully this isn't confusing!
