Step-by-step explanation:
Y=-8 so any x with the coordinate -8 for y i guess.
Answer:
254 cm² (to 3 s.f.)
Step-by-step explanation:
Area of shaded region
= area of large circle -area of smaller circle
Radius of large circle= 15cm
Radius of smaller circle= 12cm
Area of shaded region
= π(15²) -π(12²)
= 225π -144π
= 81π
= 81(3.14)
= 254.34
= 254 cm² (3 s.f.)
The relationships that could have a negative correlation are as follows:
- the speed of a train and the length of time to reach the destination
- number of hours worked and free time
- speed of a car and minimum stopping distance
<h3>What is negative correlation?</h3>
Correlation between two variables shows the relationship between the two variables.
A positive correlation means that both variables move in the same direction i.e. as one increases, the other increases.
However, a negative correlation means that both variables are inversely related i.e. one increases as the other decreases.
Therefore, the relationships that could have a negative correlation i.e. inversely related are as follows:
- the speed of a train and the length of time to reach the destination
- number of hours worked and free time
- speed of a car and minimum stopping distance
