The Median for this is 220.5
Bumek [7]3 years ago
5 0

Answer:

The median is 220.5

Step-by-step explanation:

Given a sample of numbers, the median of the sample represents the number which is in the middle of the sample. It's always convenient to have the sample ordered from the least to the greatest number.

For example, for the sample :

1,7,5

The first step is to order the sample :

1,5,7

For this sample, the number 5 is in the middle.

It's important to know that given a sample that has an odd number of numbers (we called this number i) and we have already ordered the sample, the median will be the \frac{i+1}{2} element.

For example, for a sample of 15 numbers which are already ordered, the element \frac{15+1}{2} = 8 (eighth element) is the median.

Also, with a sample containing an even number of numbers (already ordered), for example x1 , x2 , ... , xi, the median of the sample is calculated as \frac{1}{2}(x_{\frac{i}{2}}+x_{\frac{i}{2}+1})

For example, for a sample of 10 numbers which are already ordered, the median is ( i = 10 ) :

\frac{1}{2}(x_{5}+x_{6})

In the exercise, there is an even number of numbers ⇒

208,220,221,302

the median is the middle value between 220 and 221 = \frac{220+221}{2}=220.5

Which two values of x are roots of the polynomial below?
Julli [10]

Answer:

B. and C.

Step-by-step explanation:

1. Set the polynomial equal to zero:

x² + 5x + 7 = 0

2. Plug the given values of a, b, and c into the quadratic formula:

x=\frac{-5+-\sqrt{5^{2}-4(1)(7) } }{2(1)}

3. Solve the square root:

x=\frac{-5+-\sqrt{25-4(1)(7)} }{2(1)}

x=\frac{-5+-\sqrt{25-28} }{2(1)}

x=\frac{-5+-\sqrt{-3} }{2(1)}

4. Simplify the rest:

x=\frac{-5+-\sqrt{-3} }{2}

5. Separate the solutions:

x=\frac{-5+\sqrt{-3} }{2}  , x=\frac{-5-\sqrt{-3} }{2}

Thus, options B and C are the answers.

hope this helps!

A rectangular parking lot has a perimeter of 232 feet. the length of the parking lot is 36 feet less then the width. find the le
Troyanec [42]

Answer:

Length: 40  Width: 76

Step-by-step explanation:

W is width, and L is length.

We know that the length is 36 less than the width, so L = w - 36.  Two times the width plus two times the length equals the perimeter, so set up the equation for the perimeter as:

232 = 2w + 2(w-36)

Now solve for w:

232 = 2w + 2w - 72

304 = 4w

w = 76

we now know that the width is 76, so solve for the length:

L= 76-36

L = 40
