A CPU manufacturer is interested in studying the relationship between clock speed and the operating temperature that results at

that clock speed for a particular CPU model. Let x be the clock speed in MHz and let Y be the temperature in ^{\circ}C . The following data was collected:i xi yi1 350 31.42 360 35.63 370 41.84 380 51.05 390 56.86 400 62.87 410 67.4a) Find the equation of the regression line.b) Estimate the temperature for clock speed x = 430 MHz.c) Find the 95% confidence interval for \beta .d) Compute the coefficient of determination R^{2} ?. Is this a high quality fit?

Find the co-ordinates of the vertex of the function y=x²-12x+2 and show your work
nataly862011 [7]

Answer:

(6,-34)

Step-by-step explanation:

You can use the vertex formula to find the x of the vertex and then plugin the x value into the formula to find the y value.

x = -\frac{b}{2a}

x = -\frac{b}{2a}

x = -\frac{-12}{2(1)}

x = 6}

Now plugin 6 into  y=x²-12x+2

y=x²-12x+2

y=6²-12(6)+2

y=36-72+2

y=36-72+2

y = -34

Vertex = (6,-34)

Please please help please
il63 [147K]

Answer:

6 times larger

Step-by-step explanation:

First, find the area of both.

Mary: 4*5.5=22

Lisa: 24*5.5=132

Then find what multiplied by 22 would equal 132. This is easy because it's a multiple-choice question.

22*20=440, so A is incorrect

We already know they are not equal, so then B can be crossed out

22*3=66, C would be incorrect

Leaving the only choice left to be the correct answer

22*6=132
