Answer:
In this section, we discuss box-and-whisker plots and the five key values. The key values are called a five-number summary, which consists of the minimum, first quartile, the set is put into increasing order, divides the data into two equal parts. First, we put the values in the data set into increasing order: 3, 5, 7, 8, 12, 13, the middle score for a set of data that has been arranged in order from least to greatest. A box-and-whisker plot shows the distribution of a set of data along with... Quartiles are values that divide a set of data into four equal parts. The second Quartile ( designated Q2) also called the median or the 50th percentile (cuts data set in half ).
Step-by-step explanation:
Please don't post a set of problems with no work of your own shown.
I would gladly involve you in answering these questions, but will not do the problems and hand you direct answers. Start with #1. What do you understand about this problem, and what do you think you need to know to be able to solve it?
we know that
the standard form of the equation of the circle is
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem we have
<u>Convert to standard form</u>
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square twice. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
the center of the circle is 
the radius of the circle is 
therefore
<u>the answer is</u>
the radius of the circle is
Answer:
81
Step-by-step explanation:
To evaluate substitute x = - 2 into the expression
4( - 2)² - 20(- 2) + 25
= (4 × 4) + 40 + 25 = 16 + 40 + 25 = 81
