yuradex [85]

Answer:

a) The mean of the data set is $33,691.13 and can be calculated by finding the average of the sum of the eight salaries.

b) The five number of the data set is {27,274; 30,421; 32,941.5; 35,682; 44,166} and can be calculated by finding the minimum, maximum, median, and interquartile range values.

c) The standard deviation of the data set is 4773.50 and can be calculated by finding the square root of the average of the sum of the differences from the mean squared.

Solve the system of equations by graphing. Look at the picture. Will Mark Brainliest​
aleksandr82 [10.1K]

Answer:

See below

Step-by-step explanation:

<h3>Graphing:</h3>

we are given two functions

\displaystyle \begin{cases}f(x) =  - x + 5 \\ g(x) =  {x}^{2}   - 3x + 2\end{cases}

where f(x) is a <em>linear</em><em> </em><em>function</em> and g(x) is a <em>q</em><em>uadratic </em>function

we want to figure out the solutions of the function

let's graph f(x):

the Black-table is attached

let's graph g(x):

the picture is attached

hence, the graph should be

the graph is attached

<h3>solutions stating:</h3>

so we need solution(s) which satisfy(ies) the both functions

in this case the solution (s) the x coordinate(s) where both functions intercept we get from the graph that both functions intercept at <u>(</u><u>-</u><u>1</u><u>,</u><u>6</u><u>)</u> and <u>(</u><u>3</u><u>,</u><u>2</u><u>)</u>

hence,

x={-1,3}
