15n > 12n + 18
3n > 18
n > 6
To get percent error you take actual-predicted and divide by the actual then multiply by 100 to get the percent.
65-50=15
15/60=0.25
0.25 times 100 =25%
Use substitution
-x + 4 = 1/3x + 8
4 = 4/3x + 8
-4 = 4/3x
x = -4 * 3/4
x = -3
Then plug x into one of the original equations. In this case y = -x + 4 is the easiest.
y = -(-3) + 4
y = 7
Do 25 divided by 1/2 to get your answer. Thanks! Brainly Team
Answer:
38.18%
Step-by-step explanation:
Experimental probability is probability that is determined on the basis of the results of repeated experiments.
Experimental Probability = The number of times a result happens / The number of times the experiment is carried out *100%
In this problem, The number of times a result happens is the number of times Pedro sees heads, which is 21. The number of time the experiment is carried out is 55.
So the result is 55/21 *100% = 38.181818... * 100%= 38.18%
Hope you learn with joy and high grades !
