A random sample of records of sales of homes in the NRV gives the price (in thousands of dollars) and size (in square feet) of the homes yielded the following regression equation: y=48.82 +0.061*x Which of the following statements is true about the slope of this regression line?
1. We predict that for every dollar price increase, the size of the house will increase by 61 feet.
2. This is an example of extrapolation so any prediction will not be a useful one.
3. We predict that for every square foot increase in the size of a house, the price will increase by .061.
4. We predict that for every square foot increase in the size of a house, the price will increase by $61.00

step-by-step explanation:

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
