Joey is asked to find the mean of this set of data: 4, 6, 7, 7, 7, 8, 12, 13, 15, 15, 17. what doe that mean

111 divided by 11 is your mean. your mean will be 10.09

Step-by-step explanation: add together all of the numbers to get the sum then divide the sum by the number of data entries(numbers) you have.

the probability is 0

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
