Answer:

c = 24

Step-by-step explanation:

The given equation is :

\dfrac{c}{2}-5=7

Adding both sides by 5 both sides,

\dfrac{c}{2}-5+5=7+5\\\\\dfrac{c}{2}=12

Cross multiplying both sides,

c=2\times 12

c = 24

So, the value of c is 24.

Triangle XYZ, X equals 27 cm, Y equals 79 cm and angle C equals 142Degrees. Find the length of Z, to the nearest centimeter.
Oksi-84 [34.3K]

Given:

In triangle XYZ, x = 27 cm, y = 79 cm and \angle C=142^\circ.

To find:

The length of z.

Solution:

In triangle XYZ, using the Law of cosine, we get

z^2=x^2+y^2-2xy\cos Z

Putting the given values in the above formula, we get

z^2=(27)^2+(79)^2-2(27)(79)\cos (142^\circ)

z^2=729+6241-4266(-0.788)

z^2=6970+3361.608

z^2=10331.608

Taking square root on both sides.

z=\pm \sqrt{10331.608}

z=\pm 101.6445178

Approx the above value to the nearest number and side length cannot be negative. So,

z\approx \pm 102\text{ cm}

Therefore, the length of z is about 102 cm.

Ghella [55]

The difference between the median of the data, including the possible outlier, and excluding the possible outlier is 2.

<h2>Given that</h2>

The number of lattes sold daily for two coffee shops is shown in the table: Lattes 55 52 50 47 68 48 53 53 Based on the data.

<h3>We have to determine</h3>

What is the difference between the median of the data, including the possible outlier, and excluding the possible outlier?

<h3>According to the question</h3>

The number of lattes sold daily for two coffee shops is shown in the table: Lattes 55 52 50 47 68 48 53 53 Based on the data.

The data set with the outlier is 20, 41, 45, 48, 52, 55, 56, 57; Meaning the median falls in between 48 and 52, which is 50.

Then the data set without the outlier is  41, 45, 48, 52, 55, 56, 57;  Making the median here 52.

Therefore,

The difference between the median of the data, including the possible outlier, and excluding the possible outlier is

= 52 -50 = 2

Hence, The difference between the median of the data, including the possible outlier, and excluding the possible outlier is 2.
