Just depends on where you live :(
sorry hun didn't provide enough info.
Cheers :3
Answer: 60, 120
Step-by-step explanation:
Let one angle be x
The other angle is 2x
x + 2x = 180°
3x = 180°
x = 180/3 = 60
Other angle is 2 * 60 = 120
Hey there! I'm happy to help!
First, let's find the slope of the two lines. To find the slope, you divide the difference in the y-values by the difference in the x-values.
LINE M
7-12/3-6=-5/-3= <u>5/3</u>
LINE N
1-6/-5+2=-5/-3=<u>5/3</u>
If lines have the same slopes, they are parallel because they are always moving at the same incline and therefore will never meet. This matches what answer A says.
Therefore, the correct answer is A) Lines m and n have the same slope so they are parallel.
I hope that this helps! Have a wonderful day!
Answer:
(1.1155 ; 1.1245)
Step-by-step explanation:
Given that :
Sample mean, xbar = 1.12
Sample standard deviation, s = 0.011
Sample size, n = 25
Since we are using the sample standard deviation, we use the T distribution ;
The confidence interval is defined as :
C. I = Xbar ± Tcritical * s/√(n)
Degree of freedom, df = n - 1 = 24
Tcritical(0.05, 24) = 2.064
C. I = 1.12 ± (2.064 * 0.011 / √25)
C.I = 1.12 ± 0.0045408
Lower boundary = (1.12 - 0.0045408) = 1.1155
Upper boundary = (1.12 + 0.0045408) = 1.1245
(1.1155 ; 1.1245)
