Answer:
8
Step-by-step explanation:
Let's say the ant is walking across the floor. Then it hits the wall and starts climbing to the ceiling.
We have a right triangle, as in the diagram, so we can apply Pythagoras' Theorem.
x² + 6² = 10²
x² + 36 = 100
x² = 64
x = 8
The ant must walk eight vertical units.
Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Number of colors that the arrow can land on = 8
We need to find the degrees of freedom for a goodness of fit test of the fairness of this spinner.
As we know that degree of freedom is 1 less than the size of sample.
So, Mathematically, it is expressed as below:
So, Degree of freedom would be
Hence, Option 'c' is correct.
