According to a study conducted in one city, 34% of adults in the city have credit card debts of more than $2000. A simple random sample of n = 400 adults is obtained from the city.

Describe the sampling distribution of p^ with caret, the sample proportion of adults who have credit card debts of more than $2000. Round to three decimal places when necessary.

answer: 414,377,008

step-by-step explanation:

just multiply it

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

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
