Answer:
B. 61%
Step-by-step explanation:
When we have the standard deviation of a sample, we use the t-distribution.
The width of an interval is related to the margin of error, which is given by the following equation:
M = T*s
In which T is related to the confidence level(and the sample size) and s is the standard deviation of the sample. Higher confidence levels have higher values of T.
A higher margin of error means that the interval is wider. To have a higher margin of error, we desire a higher value of T, which is achieved with a higher confidence level.
So the correct answer is:
B. 61%
Two lines and a point are guaranteed to be coplanar if the two lines share only a single point.

Answer:
x = 19
z = 64
Step-by-step explanation:
Angles (11x - 93)° and 116° are vertical angles, so their measures are equal.
11x - 93 = 116
11x = 209
x = 19
Angles z° and 116° are a linear pair, so they are supplementary, and their measures have a sum of 180°
z + 116 = 180
z = 64
Answer:
The table is missing in the question. The table is provided below.
Step-by-step explanation:
1. In the table, it is given the difference of high temperature. They are :
-7, -7, 2, 5, -3, -2
Now adding the differences of high temperatures and taking out its average.
-7 + (-7) + 2 + 5 + (-3) + (-2)= -12
Average : 
Thus the answer is an integer.
2. In the table, it is given the difference of high temperature. They are :
0, -3, -7, -1, 1, 0
Now adding the differences of high temperatures and taking out its average.
0 + (-3) + (-7 )+ (-1) + 1 + 0= -10
Average : 
Thus, the answer is not an integer. The answer lies between the integers -2 to -1.
