The true quadratic regression function is e{y}=15+20x+3x2. the fitted linear regression function is y^=13+40x, for which e{b0}=10 and e{b1}=45. what are the bias and sampling error components of the mean squared error for xi=10 and xi=20?

it would rotate about 180 degrees.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

idk what the heck he answer is, i’m just putting this here so i finish my account

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
