Rule: Adding up the three angles of any triangle always results in 180 degrees
F+U+N = 180
(x+21) + (x+23)+(x+61) = 180
x+21+x+23+x+61 = 180
(x+x+x)+(21+23+61) = 180
3x+105 = 180
3x+105-105 = 180-105
3x = 75
3x/3 = 75/3
x = 25
If x = 25, then angle N is...
N = x+61
N = 25+61
N = 86

Answer: 86 degrees
Answer:
1. There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.
Step-by-step explanation:
A p - value less than 0.05 means that the test hypothesis is false or rejected.
In this question the test hypothesis is H 0 : mu=79 which is false as p-value is 0.035.
Whenever the p- value is less than the significance level H0 is rejected.
Hence the null hypothesis is rejected.
Therefore only choice 1 is correct.
There is sufficient evidence to conclude that listening to soothing sounds increases the mean test score.
There is sufficient evidence to support the claim.
The answer I think should be right would be 3.
It’s odd because you need to round it. But anyway I hope this helped. Rate my answer if I was wrong or correct
- 12. What do you mean by that question? -12 itself is an integer.
What are the 7 & 9 for? Obviously, you had info from somewhere else for the 9 & 7 if they are THE ONLY NUMBERS here
