Answer: 39.308 pounds
Step-by-step explanation:
We assume that the given population is normally distributed.
Given : Significance level :
Sample size : n= 12, which is small sample (n<30), so we use t-test.
Critical value (by using the t-value table)=
Sample mean :
Standard deviation :
The lower bound of confidence interval is given by :-
i.e.
Hence, the lower bound for the 98% confidence interval for the mean yearly sugar consumption= 39.308 pounds
These angles are supplementary, meaning that their sum should be 180.
Write an equation.
5x+110=180
5x+110-110=180-110
5x=70
x=14
To find the angle measure,
multiply 5 by 14.
5 x 14= 70
To check:
70+110=180
Therefore, the variable has a value of 14.
Answer:
18.55, lines m and n are parallel and t is the transversal. If ∠1 = 130o, find the measures of the other angles and give reasons.
