Answer:

1/12

Step-by-step explanation:

1/6 x 1/2 = 1/12

The answer would be 1/6 IF you took 1/6 of the full sheet of paper, but if you are taking 1/6th of half of the paper, then you are taking half the amount. Basically, you would need two 1/6 pieces of one half to be equivalent to one 1/6th piece on the full sheet.

Answers

Answer:

x = √149

Step-by-step explanation:

Compartmentalize the odd figure into a rectangle (with sides 3 and 7) and a triangle (with sides 10 and x). Now, that you have a triangle, you can use the rectangle underneath to find the bottom side of the triangle--it is 7. The triangle that has been formed is a right triangle, so we can use the Pythagorean Theorem to find x, which is the hypotenuse.

10² + 7² = x²

100 + 49 = x²

149 = x²

√149 = x

Answer:

7√2

Step-by-step explanation:

Remark

Draw another line parallel to 7.

Move to the other end of 3

that makes the vertical leg on the left 10 - 3 = 7

You now have a smaller right triangle.

Equation

a = 7

b = 7

c = x

Solution

x^2 = 7^2 + 7^2

x^2 = 49 + 49

x^2 = 98

x^2 = 7 * 7 *2

sqrt(x^2) = sqrt(7 * 7 * 2)

The rule about square roots is for every pair of factors you can take one out of the square root sign and throw the other one away.

x = 7 sqrt(2)

The box plots show the data distributions for the number of customers who used a coupon each hour during a two-day sale.



Which measure of variability can be compared using the box plots?



interquartile range



standard deviation



mean



median

Answers

Answer:

Interquartile age

Step-by-step explanation:

The box plots that is being referred to are missing, however, we can still answer this without the box plots.

The appropriate measure of variability that can be easily determined by a box plot is the interquartile range. Which is the difference between the 3rd quartile and the 1st quartile.

On a box plot, the first quartile is the data value ta the beginning of the edge of the rectangular box while the third quartile is at the end of the edge of the rectangle box. So, this makes is easy for use interquartile range as a measure of variability when comparing both.

Answer:

Interquartile range (IQR)

explanation:

Mean and median are both measures of center so it can't be those two, and the standard deviation is a measure of variability but only when the graph, box plot or any other type of graph is symmetric

99-40 =59

Step-by-step explanation:

Given that

We write the expression i.e. half of the sum of $9 and a number

Here we need to write the two expression that is different from each other

So,

Let us assume the number be x.

Now The first equation depend on the information given will be:

= 1 ÷ 2(9 + x)

And, The second equation is

= (9 + x) ÷ 2

Read the excerpt from Votes for Women:Taking a more aggressive approach to women's suffrage was arguably more impactful in the short term. Alice Paul learned how to use this aggressive approach in England and brought it to the United States. For a while, she held a leadership position with the National American Woman Suffrage Association. She helped organize the March on Washington held on March 2, 1913, the day before President Wilson's inauguration. The parade was led by a human rights lawyer riding a white horse, and behind her women marched in costumes reflecting the nations that had already given women the vote. Multiple floats, bands, brigades, and costumed women paraded on through Washington, D.C. However, during the parade of protest, some men attacked the women and behaved poorly, and the police did nothing to stop it. The actions of the men led to an inquiry, which brought women's suffrage significant public awareness. However, some women did not agree with Paul's methods. Paul ultimately formed a separate group, which became known as the National Woman's Party. This group of women held marches and hunger strikes. They were also the first organization to organize a picket of the White House in January 1917. While their choice to picket during World War I angered some, their methods did make an impact and paved the way for women's suffrage to become law.Both peaceful and aggressive approaches contributed to the ratification of the 19th Amendment on August 18, 1920. On November 2, women across the nation voted, which marked the beginning of the ongoing struggle to reform the rights of women in the United States.Which sentence gives a point made by the author of Votes for Women?a. Alice Paul formed a group called the National Women's party.Selected:b. Alice Paul organized a women's March on Washington.This answer is incorrect.c.
