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.
You will want to divide the shape up into different parts to solve this. For example, first I would take the top rectangle (24x5=120) and add the answer of that to the rectangle in the middle section (120+(11x10)=230). Then, I would add the very last rectangle at the very bottom of the total we have so far (230+(7x3)=251). Lastly, I would take the semi-circle and find its area ((3.14x2)^2)/2=19.7192). Then, add all of the totals together and get your answer of
= 250.7192km^2
*note, only put the number of decimals needed.

Not the correct answer
I tried my best
<h3><u>Part A</u></h3>
To show the total capacity of container B is 132 cm³
volume = unit rate × time taken
volume = 6 cm³ × 22
volume = 132 cm³ ∴ Hence proved.
<h3 /><h3><u>Find radius</u></h3>

===================

<em>simplify</em>

<em>change sides</em>

<em>square root both sides</em>
∴ Hence the radius of cone (Shape B is 3 cm)
<h3><u>To show the time taken</u></h3>
volume = unit rate × time taken

=========================

<em>Insert values</em>

<em>exchange sides</em>

<em>simplify following</em>

A) 2.0+3.4n
b)90-5n
c)33 1/2+5n
