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 = 12.5% = 0.125
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 12.5% of U.S. workers belong to union and the alternate hypothesis states that there is a increase in union membership.
This is a one-tailed(right) test.
Formula:
Putting the values, we get,
Now, we calculate the p-value from the table.
P-value = 0.3812
Since the p-value is greater than the significance level, we fail to reject the null hypothesis and accept the null hypothesis.
Conclusion:
Thus, there is not enough evidence to support the claim that union membership increased.
Answer:
-1/7
Step-by-step explanation:
Divide the first expression by the second expression.
Multiply each term by a^2b^2:-
b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2 = a^2b^2 - a^2x^2
Now divide both sides by b^2
y^2 = a^2 - a^2x^2 / b^2 = a^2 (1 - x^2/b^2)
take positive square root ( because y > 0)
y = a sqrt(1 - x^2/b^2)
Answer:
The Width of the Rectangle =
Step-by-step explanation:
The area of the rectangle 
We are told that the width of the rectangle is equal to the greatest common monomial factor of 
Let us determine the greatest common monomial factor of
Express each term as a product to pick out the common factors:
In the two terms, the common terms are 10 and 
. Therefore their greatest monomial factor =
The Width of the Rectangle =
Recall: Area of a Rectangle =Length X Width
Answer:
B. 
Hope this helped. A brainliest would be very much appreciated. (I need 4 brainliest so I can level up) :)
