Answer:
X=15
Step-by-step explanation:
A +B + C = 180
2x +4x+ 6x = 180
12x =180
X= 15
Answer:
n=4
Step-by-step explanation:
Given equation: \[\frac{1}{n-4}-\frac{2}{n}=\frac{3}{4-n}\]
Simplifying the Left Hand Side of the equation by taking the LCM of the denominator terms:
\[\frac{n}{n*(n-4)}-\frac{2*(n-4)}{n*(n-4)}=\frac{3}{4-n}\]
=> \[\frac{n - 2*(n-4)}{n*(n-4)}=\frac{3}{4-n}\]
=> \[\frac{n - 2n + 8}{n*(n-4)}=\frac{3}{4-n}\]
=> \[\frac{8 - n}{n*(n-4)}=\frac{3}{4-n}\]
=> \[(8-n)*(4-n) =n*(n-4)*3\]
=> \[n-8 =3n\]
=> \[2n =8\]
=> n = 4
By definition a counting number is all non-negative integers.
Answer:
14/50 or 7/25 or 0.28 or 28%
Step-by-step explanation:
The spinner is spun 50 times. (8+6+9+11+9+7=50)
It lands on 1 or 2 a total of 14 times. (8+6=14)
So the experimental probability is 14 out of 50. There are several ways this can be represented. It depends on what your teacher wants. it could be as a fraction or a decimal or a percentage.
14/50 or 7/25 or 0.28 or 28%
Answer:
The conclusions apply only to the sample.
Step-by-step explanation:
Since the sample size is small, it's not likely to be representative of any larger population.
I hope this helps!
