Part l:find the x-intercepts of the parabola and write them as ordered pairs. Hint: the x-intercepts are the points at which the function crosses the x-axis and y=0. Show your workPart ll:Write the equation y=(x-4)(x+2) in standard form. Show your work.Part lll:with the standard form of the equation from part ll, use the quadratic formula to identify the x-value of the vertex. Hint: the x-value of the vertex is -b/2a. Show your workPart lV:substitute the x-value of the vertex from part lll into the original equation to find the y-value of the vertex. Then, write the coordinates of the vertex

To encourage efficiency at a drive through window, a fast food restaurant chain specifies, as a guideline, that at least half of all drive through orders should be taken, prepared, and delivered in 3 minutes or less. Subsequently, a random sample of 64 drive through orders was taken and it was found that 24 of them were taken, prepared and delivered in 3 minutes or less. The remaining orders from the sample took longer than 3 minutes. The fast food company would like to know if they are meeting the specified guideline. Which test should be used?Single sample test of means with unknown variance (standard deviation)Two sample test of proportionsSingle sample test of proportionsTwo sample test of means with unknown variance (standard deviation)
