Answer:
m ∠ W is 58.2°
Step-by-step explanation:
Given:
XY = 15
WZ = 22
∠ XZY =25°
To Find:
m ∠ W = ?
Solution:
In right angle triangle Δ XZY, by Sine identity we have
∴ XZ = 35.49
Now in right angle triangle Δ WZX, by tangent identity we have
∴m ∠W =58.2°
Answer:
There is not enough evidence to support the claim that union membership increased.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 400
p = 11.3% = 0.113
Alpha, α = 0.05
Number of women belonging to union , x = 52
First, we design the null and the alternate hypothesis
The null hypothesis sates that 11.3% of U.S. workers belong to union and the alternate hypothesis states that there is a increase in union membership.
Formula:
Putting the values, we get,
now, we calculate the p-value from the table.
P-value = 0.141636
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Thus, there is not enough evidence to support the claim that union membership increased.
just a quick note, that triangle is misleading some, since the HG side of 6 units, shows longer than GE which is 8, and of course 8 > 6.
Since GE is a perpendicular bisector, that means the angle at G is 90°.
