High school statistical reasoning ( my teacher is awful)

metabolic rate metabolic rate, the rate at which the body consumes energy, is important in studies of weight gain, dieting, and exercise. we have data on the lean body mass and resting metabolic rate for 12 women who are subjects in a study of dieting. lean body mass, given in kilograms, is a person’s weight leaving out all fat. metabolic rate is measured in calories burned per 24 hours. the correlation is = 0.88

a.) what would happen to the correlation is metabolic rate was plotted on the horizontal axis and lean body mass was plotted on the vertical axis? explain

b.) what would happen to the correlation is lean body mass was measured in pounds instead of kilograms? explain.

c.) howard claims that the correlation between metabolic rate and lean body mass is = 0.88 cal/kg. is this correct? explain.

step-by-step explanation:

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
