A contractor records the areas, in square feet, of a small sample of houses in a neighborhood to
determine data about the neighborhood. They are:
2,400; 1,750; 1,900; 2,500; 2,250; 2,100
Which of the following represents the numerator in the calculation of variance and standard deviati
(225)2 + (-425)2 + (-275)2 + (325)2 + (75)2 + (-75)2 = 423,750
(650)2 + (-150)2 + (-600)2 + (250)2 + (150)2 + (-300)2 = 980,000
✓ (250)2 + (-400)2 + (-250)2 + (350)2 + (100)2 + (-50)2 = 420,000
COMPLETE
What is the variance?
What is the standard deviation, rounded to the nearest whole number?

69.64%

step-by-step explanation:

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

the answer is b.
