Answer:
52.........................
since r is positive, the correlation is also positive also, since r is closer to 0 than 1, the correlation is weak
Answer:
60 push-ups
Step-by-step explanation:
Set up a ratio to represent the problem:
Molly : Liza
10 : 15
40 : ?
How did we get from 10 to 40?
You multiply by 4. Therefore, multiply by 4 on both sides of the ratio.
10 : 15
x4 x4
40 : 60
So, Liza does 60 push-ups while Molly does 40.
Answer:
x = 3; y = 6; z =4
Step-by-step explanation:
The point J is the circumcentre of the triangle.
It is equidistant from the vertices. So
2x + 2 = 8
2x = 6
x = 3
2y - 4 = 8
2y = 12
y = 6
If FI = 9, HI = 9. Then,
3z - 3 = 9
3z = 12
z = 4
So, x = 3; y = 6; z =4.
