The answer is -8

I found my answer by using desmos. It is the best app for graphing. I wrote the equation and then I looked for the point 18 on the y axis and then I looked where it was on the x axis

that is how I found my answer.

Triangle QRS is a right triangle.

olasank [31]

Answer:

5.3

Step-by-step explanation:

a² + b² =² c² the Pythagorean theorem

RQ² + RS² = QS² Solve RS

6² + RS² = 8²

RS² = 64 -36

RS² = 28

RS = √28 28 is slightly > 25 and since √25 =5

RS = 5.3 actually 5.2915 to a few more significant digits

A data analyst has spreadsheets numbered

algol [13]

Answer:

$\frac{2}{9}$

Step-by-step explanation:

${\textrm}{Total number of objects here} = 9$

(2 spreadsheets, 3 databases and 4 presentations,

${\textrm}({Total} = 2+3+4 = 9)$

${\textrm}{No. of databases with an odd number} = 2 {\textrm}{(databases with number 1 and 3})$

As not mentioned other wise equal chances of all the outcomes is assumed so, by the classical definition of probability,

P(The chosen item is a odd numbered database)

= $\frac{2}{9}$
