Answer:
100°
Step-by-step explanation:
Since the angles om a straight line add up to 180°
10x°+8x°=180°
18x°=180°
x=10
The larger angle = 10x°
= 10(10)°
= 100°
Answer:
1/4
Step-by-step explanation:
1/2 × 2/3
= 1×3 = 1
2×2 = 4
Therefore,
1/2 × 2/3 = 1/4//
Answer:
Number 1 would be figure 2
Number 2 would be figure 1
Number 3 would be figure 3
Step-by-step explanation:
A correlation coefficient describes the relationship between two variables. A zero shows that there is no correlation while a one describes a positive correlation. A negative one describes a negative correlation. Since all of the dot in the scatter plot in figure 2 are spread out and not in a line, it has no correlation or you could say that it's coefficient is zero. Since the dots in figure 1 are going from left to right and are close together, it has a positive correlation. Since the dots in figure three are going right to left and resemble a line, the correlation coefficient is -1.
