Answer:

The answer is "0.0764"

Step-by-step explanation:

Please find the complete question in the attached file.

$\to \mu = \$ \ 4064\\\\\to \sigma = \$ \ 460 \\\\\to \sigma \bar{x} = \frac{\sigma}{\sqrt{n}}\\\\$

$= \frac{460}{\sqrt{21}}\\\\ = \frac{460}{4.58257569}\\\\=100.3802$

$\to P(\bar{x}< \$ \ 3920) = \frac{P((\bar{x} - \mu \bar{x})}{\frac{\sigma \bar{x}$

$\to P(z < -1.43) = 0.0764 \\\\\to P(\bar{x}< \$ \ 3920) = 0.0764\\\\$

Answer:

The correct answer is: Option D: 26 vehicles

Step-by-step explanation:

Median is the middle value of a sorted data set.

The formula for median depends on the number of values in the dataset.

First of all we have to arrange the given data in order

So,

14 19 23 24 24 24 24 26 26 26 26 26 27 27 28 29 30 30 30 34

Counting the values in the dataset

n = 20

As the number of values is even, the formula for median will be

$M = \frac{1}{2}(\frac{n}{2}th\ value+(\frac{n}{2}+1)th\ value)$

Putting the values

$M = \frac{1}{2}(\frac{20}{2}th\ value+(\frac{20}{2}+1)th\ value)\\M=\frac{1}{2}(10th\ value +[10+1]th\ value]\\M= \frac{1}{2}(10th\ value + 11th\ value)$

The 10th value in dataset is 26 and 11th is also 26 so

$M = \frac{1}{2}(26+26)\\M = \frac{1}{2}(52)\\M = 26$

Hence,

The correct answer is: Option D: 26 vehicles

If each interior angle of a regular polygon measures 144º, how many sides does it have?

12345 [234]

Answer:

Brainliest!

Step-by-step explanation:

Since the interior angle is 144 degree, each exterior angle is 180 - 144 = 36 degrees

number of sides = 360/36 = 10

The polygon is decagon with 10 sides
