The table shows the median home prices in Florida. What is the equation of a trend line that models a relationship between time

and home prices? Use the equation to predict the median home price in 2020.
Year                            Median Price($)

1940                            $20,200

1950                             $39,900

1960                            $50,400

1970                           $62,800

1980                          $89,100

1990                          $98,700

2000                        $119,000

Answer:

A) Price= 1617*Year - 3.116e+006;     B) 150340$ By 2020

Step-by-step explanation:

We have a data set of 7 x, y pairs, this data set can be modelled as line, applying a linear regression calculator we found that the trend line can be modelled as Price= 1617*Year - 3.116e+006  

Attached you will find the regression results where x is the year variable and Y is the price. If we now plug year=2020 in the equation we have:

Price=1617*2020-3.116e+006 = 150340$

Elodia [21]

Answer:

B

Step-by-step explanation:

  • He starts out with 30
  • He adds 5 coins each month
  • x represents the number of months

>60 means greater than 60

So the inequality would be 30 + 5x > 60

PLEASE PLEASE HELP! Find the measure of APB^.
Whitepunk [10]

Answer:

65°

Step-by-step explanation:

Radii CA and CB are perpendicular to tangent lines AT and BT, so

\angle CAT=\angle CBT=90^{\circ}

Since angle BAT is equal to 65°, angle CAB has measure

\angle CAB=90^{\circ}-65^{\circ}=25^{\circ}.

Consider triangle ACB. This triangle is isosceles, because CA=CB as radii of the circle. Two angles adjacent to the base are congruent, thus

\angle CBA=\angle CAB=25^{\circ}

The sum of the measures of all interior angles in triangle is always 180°, so

\angle CAB+\angle CBA+\angle ACB=180^{\circ}\\ \\25^{\circ}+25^{\circ}+\angle ACB=180^{\circ}\\ \\\angle ACB=130^{\circ}

Angle ACB is central angle subtended on the minor arc AB, angle APB is inscribed angle subtended on the same minor arc AB. The measure of inscribed angle is half the measure of central angle subtended on the same arc, so

x=\angle APB=\dfrac{1}{2}\cdot 130^{\circ}=65^{\circ}
