Medain of 38,42,77,47,74,51,48,41,82,72,74,129

uranmaximum [27]

Answer:

The median of 38, 42, 77, 47, 74, 51, 48, 41, 82, 72, 74, and 129 is 61.5.

Step-by-step explanation:

First, rearrange the data set in order.

38, 42, 77, 47, 74, 51, 48, 41, 82, 72, 74, 129

38, 41, 42, 47, 48, 51, 72, 74, 74, 77, 82, 129

Identify how many numbers are in the set. This will make it easier to infer the median.

Counting will show that this is a 12 number data set.

To find the median:

If there are an ODD amount of numbers in a data set, take the middle number. That is your median.

If there are an EVEN amount of numbers in a data set, take the middle two numbers, add them, then divide that by 2. That is your median.

Knowing this, take your middle two numbers, 51 and 72, and add them and divide by 2.

51 + 72 = 123

123/2 = 61.5

The median of this data set is 61.5.

A right triangle, DEF, is shown below.<br><br> What is sin FDE?

RoseWind [281]

Answer:

22.6°

Step-by-step explanation:

Reference angle = <FDE

Side opposite to <FDE = 5

Hypotenuse = 13

The trigonometric ratios to apply is:

$sin(\theta) = \frac{opp}{hyp}$

Plug in the values

$sin(\angle FDE) = \frac{5}{13}$

$sin(\angle FDE) = 0.3846$

$\angle FDE = sin^{-1}(0.3846)$

$\angle FDE = 22.6$ (nearest tenth)

Explain the steps needed to determine the value of the expression shown below be sure to provide the correct value of the expres

inn [45]

Answer:

-3/2

Step-by-step explanation:

In the picture attached, the complete question is shown.

The expression is:

$\frac{ \frac{1}{2} }{ \frac{-2}{5}} + \frac{-1}{4}$

You can rewrite the first term, expressing the division as a multiplication, that is, inverting the fraction in the denominator, as follows:

$\frac{1}{2} \times \frac{-5}{2}+ \frac{-1}{4}$

$\frac{-5}{4} + \frac{-1}{4}$

The addition of a negative fraction is simply the subtraction by that fraction:

$\frac{-5}{4} - \frac{1}{4}$

$\frac{-5 - 1}{4}$

$\frac{-6}{4}$

Which can be simplified dividing by two both numerator and denominator:

$\frac{-3}{2}$

At what ordered pair is "Parking Lot B" located at?

Arlecino [84]

The ordered pair of the parking lot is the coordinates of the lot in the coordinate plane

Parking lot B is located in the ordered pair (-3,4)

<h3>How to determine the ordered pair of lot B</h3>

From the figure, we have the following highlights

Parking lot B is located at x = -3 on the horizontal axis, and it is located at y = 4 on the vertical axis.

So, we have:

(x,y) = (-3,4)

Hence, parking lot B is located in the ordered pair (-3,4)
