Hello!

The answer to your question is false.

1/3 is not equal to 1/6 because of the numberator. 1/3 will be equal to 2/6,3/9, and 4/12. The denominator multiplies by 3 and the numerator multiplies by the next fraction. so how to get 2/6 multiply 1*2 to get 2 and 3*2 to get 6. Your answer will be 2/6.

Hope This Helps!

Answer: No, 1/3 is equal to 2/6

Step-by-step explanation: If you multiply the bottom number, the denominator, and the top number, the numerator, by 2, you will get 2/6 which is equal to 1/3.

Answer:

range °° heights - lowest = 22-12 = 10

mean °° average number = sum of all numbers÷ number of digits = 173÷ 11 =15.727

A study found that, in 2005, 12.5% of U.S. workers belonged to unions (The Wall Street Journal, January 21, 2006). Suppose a sam

Julli [10]

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

$H_{0}: p = 0.125\\H_A: p > 0.125$

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:

$\hat{p} = \dfrac{x}{n} = \dfrac{52}{400} = 0.13$

$z = \dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

Putting the values, we get,

$z = \displaystyle\frac{0.13-0.125}{\sqrt{\frac{0.125(1-0.125)}{400}}} = 0.3023$

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.

Among all pairs of numbers with a sum 57 find the pair whose product is maximum

GarryVolchara [31]

We know that

comparing the problem with the geometry, the rectangle with the largest area (maximum product of two numbers) is the square.
therefore
The pair of numbers, for 57, is 57/2 or 28.5
so
28.5+28.5----------> 57
28.5*28.5-----------> 812.25

the answer is
the pair is 28.5 and 28.5
