The table lists the results from a survey (of questionable accuracy) of adults and how much they spend on a night out.
the table displays the values rounded to the nearest whole number.
make a scatter plot. how would you describe the correlation between a person’s age and how much he or she spends on a night out?
does anyone know how to do

The correct answer is:

The correct scatter plot is attached.

There appears to be a negative correlation between a person's age and the amount they spend on a night out.

Explanation:

Age will be the independent variable, along the x-axis, and the cost of a night out will be the dependent variable, along the y-axis.

The ages range from a low of 20 to a high of 45. We will start our graph at 0 and use a scale of 5s along the x-axis, going to 45.

The amounts for a night out range from a low of 38 to a high of 58. We will start our graph at 0 and use a scale of 5s along the x-axis, going to 60.

We then plot each point as a coordinate of (age, amount spent).

Once we get the graph plotted, we see there is a negative trend in the data. As the age increases, the amount spent out decreases.

answer is the last option

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
