Answer:
l = (S - 2wh)/(2w + 2h)
Step-by-step explanation:
S = 2lw + 2wh + 2hl
S - 2wh = 2lw + 2hl
S - 2wh = l (2w + 2h)
(S - 2wh)/(2w + 2h) = l
Answer:
8
Step-by-step explanation:
Vertical angles are congruent, so 9n=8n+8. It follows that n=8.
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.
Seconds because one second is less than one minute
X time 0.8 (or 80 percent)= 15
so 15/0.8=X
18.75
