- The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.
Step-by-step explanation:
According to the graph, the line passes the y-axis at 3. Therefore, our y-int is (0, 3).

Step-by-step explanation:
Let x be the wait times before a call is answered in phone calls.
The claim is x bar <3.3 minutes
Sample size n =62
Sample mean - x bar = 3.24 minutes
Population std dev =
Since population std dev is known and also sample size is sufficiently large, we can use Z test.
(one tailed test)
Mean difference = 3.24-3.3 = -0.06 min
Std error of sample =
Z = tset statistic = 
p value = 0.119
Since p value > alpha, we accept null hypothesis.
There is no evidence to support the claim at alpha = 0.08

Answer:
Supplement to ∠ABC: ∠DAB acts as a possible supplement
Step-by-step explanation:
There are two approaches to this problem:
1. We can identify an angle by it's measure such that it adds to 180° when added to the m∠ABC
2. As this shape is a quadrilateral, we can tell that two adjacent angles are supplementary to one another, and thus can be identified as the supplement to ∠ABC
For the simplicity, lets take the second method into consideration. We see that ∠ABC is adjacent to the two angles - ∠BCD, ∠BAD. These angles can be rewritten as such: ∠DCB, ∠DAB. And, as we can see from the options, ∠DAB is one of them that may act as a supplement. Shall we check?
The m∠ABC is 110° (degrees) so that it's claimed supplement, ∠DAB should be 70° as to satisfy the first condition of adding to 180°. And, we can see from the diagram that 40° + 30° = 70° so that both "approaches" are met!
