Answer:

Step-by-step explanation:

For funding out the median firstly we need to arrange the data in ascending or descending order . Here on arranging the given data in ascending order we have ,

3,4,4,4,5,7,7,8,9,12

The median is the middle most observation , in case of odd nos . And the mean of two middlemost observations in case of even nos . Here the number of data is even , and the two middlemost observations are 5 and 7 , so ,

=> Median = x₁ + x₂ / 2

=> Median = 5 + 7/2

=> Median = 12/2

=> Median = 6

<h3>Hence the median of the given data is 6 .</h3>

Answer:

The median is 6

Step-by-step explanation:

First put the numbers in order: 3,4,4,4,5,7,7,8,9,12

Here, the 5th & 6th terms are 5 &7

So, median = 5+7/2

=12/2

The angle of rotation at which point A’ coincidences point

anygoal [31]

Answer:

216 degrees

Step-by-step explanation:

Given that ABCDE is a regular pentagon.

Hence each angle would equal = {2(5)-4}/5 right angles

=6(90)/5 =108 degrees

Since regular pentagon rotation will not disturb the shape.

When counterclockwise rotated, if 108 degrees rotated A would become E.

For another 108 degrees A would come to D

Hence angle required for rotation for A to coincide with D = 2(108)

=216 degrees

In a standard normal distribution, what z value corresponds to 17% of the data between the mean and the z value?

hjlf

You're looking for a value $z$ such that

$\mathbb P(0$

Because the distribution is symmetric, the value of $z$ in either case will be the same.

Now, because the distribution is continuous, you have that

$0.17=\mathbb P(0$

The mean for the standard normal distribution is $0$ , and because the distribution is symmetric about its mean, it follows that $\mathbb P(Z$ .

$0.17=\mathbb P(Z$

You can consult a $z$ score table to find the corresponding score for this probability. It turns out to be $z\approx0.4399$ .

Put these numbers in order from least to greatest 12%, -1/2, 0, -0.22, 0.56

uysha [10]

Answer: -1/2, -0.22, 0, 12%, 0.56

Step-by-step explanation:

-1/2 is equal to -0.50, making it the number with the least value.

-0.22 is closer to 0 than -0.50, meaning it is greater then -0.50 and less than 0.

0 is between the negative and positive numbers, giving it the spot that it has.

12% is equivalent to 0.12, meaning it is more than 0, and less than 0.56, which is the greatest number.

0.56 has more value than any other number in the problem, meaning it goes last in the order.

The polynomial 3x2 is a with a degree of .

ZanzabumX [31]

To determine the degree of a polynomial, you look at every term:

if the term involves only one variable, the degree of that term is the exponent of the variable
if the term involves more than one variable, the degree of that term is the sum of the exponents of the variables.

So, for example, the degree of $7x^{55}$ is 55, while the degree of $xy^2z^4$ is $1+2+4 = 7$

Finally, the term of the degree of the polynomial is the highest degree among its terms.

So, $3x^2$ is a degree 2 polynomial (although it only has one term)

similarly, $x^2y + 3xy^2 + 1$ is a degree 3 polynomial: the first two terms have degree 3, because they have exponents 2 and 1.
