I hate Time4Learning. I took that back in middle school.
Here's how these expressions work together. First, you need to remember WZY is a right angle (90 degrees). Now, keep that in mind when we add both equation.
3c + 2c + 2 - 7 = 90
5c - 5 = 90
5c - 5 + 5 = 90 + 5
5c = 95
5c/5 = 95/5
c = 19. Now, put 19 in the place of c and solve.
3(19) + 2 = 57 + 2 =
59 degrees.
The measurement of angle WZX is equal to 59 degrees, B.
Answer:
His 95% confidence interval is (0.065, 0.155).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
His 95% confidence interval is (0.065, 0.155).
The following information will help us with this problem:
When we use that information in the context of this problem, we can find:
Thus, a = 15, b = 7, and c = 4.
Answer:
6
Step-by-step explanation:
Since the x coordinate is the same, we only have to look at the y coordinate
3 - -3 = 3 +3 = 6
The distance is 6
Answer:
parallel
Step-by-step explanation:
Solve both equations for y to make it easier to compare them.
2x - 5y = 0 ↔ 5y = 2x, or y = (5/2)x.
y = (5/2)x - 3
Since the slopes are the same, the two lines are parallel.
