Answer:

x=3

Step-by-step explanation:

If y is 15 when x is 5, and y =f(x), then the equation is y=3x. Substitute in 9 for y, and do the algebra, and you will get 3. Hope this helped :D

1 ejemplo en donde se aplique las medidas de tendencia central (moda, media y mediana)
Mamont248 [21]

An example of a situation where the measures of central tendency can be applied is when analyzing the test scores of a Math exam taken by 11 people.

<h3>What is an example of measures of central tendency in use?</h3><h3 />

Assuming that 11 people took a Math exam that was graded out of 20 and got the results:

6, 8, 9, 10, 10, 14, 15, 15, 15, 18, 18

The median in this set would be 14. This would therefore show us what the person with the middle score got which is useful in knowing the whether people were above the middle score, or below it.

The mode in this dataset is 15 which shows that 15/20 was the score that was most acquired by people who took the exam.

The mean is:

= (6 + 8 + 9 + 10 + 10 + 14 + 15 + 15 + 15 + 18 + 18) / 11

= 12.5

On average therefore, people got a score of 12.5 in this example. This gives an overall view of the difficulty of the exam.

Find the missing side lengths. leave your answers as radicals in simplest form.
victus00 [196]

Answer:

v = 1

u = 2

Step-by-step explanation:

Given is a special right triangle with angle measures as follows:

90-60-30

The side lengths would be :

2x- x\sqrt{3}-x

in the image it shows that the second side length (the one that sees angle measure 60) is \sqrt{3} from this we can conclude x = 1 so:

v = 1 and

u = 2

Carlo is building a wooden box that is shaped like a cube. He wants the box to have a volume of 64 cubic inches.What is the area
atroni [7]
<h3>Answer:  16 square inches</h3>

Explanation:

Apply the cube root to 64 to get \sqrt[3]{64} = 64^{1/3} = 4

The exponent 1/3 is handy if your calculator doesn't have a cube root button.

This wooden cube has side lengths of 4 inches each.

Each square face will have an area of 4^2 = 4*4 = 16 square inches.
