Answer:

Hi there!

The correct answer to this question is: 56.55

Step-by-step explanation:

A semicircle is another way of saying half a circle, if we know the area of a circle is A= π * r^2   then all we have to do is take this equation and divide it by  two to get the area of a semicircle. Additionally since we are given the diameter we need to divide that by 2 to get the radius which is six.

Now we can plug all the components into the equation: A= (1/2)(π)(6^2)

you get 56.55

Which of these numbers is irrational?<br> -3.5<br> 3.5<br> ОО<br> 35<br> √5 help
Molodets [167]

Answer:

  √5 is irrational

Step-by-step explanation:

A rational number is one that can be written exactly as an integer or ratio of integers. Written as a decimal number, it will have a finite number of digits, or a repeating decimal fraction.

<h3>Application</h3>

Usually, a number that can <em>only</em> be expressed <em>exactly</em> using a <em>symbol</em> will be irrational. For square roots, any root of an integer other than a perfect square will be irrational.

The integer 5 is not a perfect square. It is between the squares 2²=4 and 3²=9. The square root of 5 is irrational.

__

<em>Additional comment</em>

A reduced fraction whose denominator has factors other than 2 or 5 will translate to a repeating decimal. The number of repeating digits may be as many as 1 less than the denominator. For example, 1/19 has an 18-digit repeating decimal equivalent.

6.338 rounded to the nearest thousand
ANTONII [103]

Answer:

6.338

this is the same because thousandths means 3 decimal places and it already has only 3 places, so it is already rounded to the thousandths. Rounded to hundredths place would be 6.34 and tenths would be 6.3.

The picture of the stem plot National  and American League is shown on the first uploaded image

Answer:

The value is \= x  = 50.14

Step-by-step explanation:

From the question we are told that

The stem plot for National League is

            2\ \ \ \ \ 9\\3\ \ \ \ \ 1 \\4\ \ \ \ \ 2\  6\  7\  8\  8\\5 \ \ \ \ \ 3\  5\  5\  5\\6 \ \ \ \ \ 3\  3\  7\\7

The  sample size is  n =  14

Generally the stem plot is interpreted in this manner

   The numbers on the first column represents the tens of a two digit number while the second column holds the possible unit number the tens in the first column can be combined with

  for example 4th row

 5           3 5 5 5

is equivalent to

53 55 55 55

Generally the mean for the national league is mathematically represented as

           \= x  = \frac{29 + 31 + \cdots + 67}{14}

=>         \= x  = \frac{702}{14}

=>         \= x  = 50.14
