First re write the sequence from smallest to largest:

12.4 14.2 15.5 17.6 18 67 73 111 336

Median is the middle value of the serie, since the number of data pointa are 9, then the middle value is 18, that is ranked in the middle or in the 5th place

!50 point question! Find x and explain how you found it!

STatiana [176]

<u>Answer:</u>

$\sf x = 60^{\circ \:}$

<u>given:</u>

adjacent side: 10
hypotenuse side: 20

<u>using cosine rule:</u>

$\hookrightarrow \sf cos(x) = \dfrac{adjacent}{hypotense}$

$\hookrightarrow \sf \sf cos(x) = \dfrac{10}{20}$

$\hookrightarrow \sf \sf x = cos^{-1}(\dfrac{10}{20} )$

$\hookrightarrow \sf \sf x = 60^{\circ \:}$

Wilma is 5 times as old as yvonne. in ten years, yvonne's age will be a third of wilma's age. how old are they now?

SVEN [57.7K]

Using a system of equations, it is found that Wilma is 50 years old and Yvonne is 10 years old.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given as follows:

Variable x: Wilma's age.

Variable y: Yvonne's age.

Wilma is 5 times as old as yvonne, hence:

x = 5y.

In ten years, yvonne's age will be a third of wilma's age, hence:

$y + 10 = \frac{1}{3}(x + 10)$

Since x = 5y:

$y + 10 = \frac{1}{3}(x + 10)$

$y + 10 = \frac{1}{3}(5y + 10)$

3y + 30 = 5y + 10

2y = 20.

y = 10.

Then:

x = 5y = 5 x 10 = 50.

Wilma is 50 years old and Yvonne is 10 years old.
