Answer:

  164 square inches

Step-by-step explanation:

You can compute the area by adding the areas of the 4 corner triangles, the 4 side rectangles and the central square.

The area of the triangle is ...

  A = (1/2)bh = (1/2)(4 in)(4 in) = 8 in²

The area of a rectangle is ...

  A = LW = (6 in)(4 in) = 24 in²

The area of the central square is ...

  A = s² = (6 in)² = 36 in²

Then the total area is ...

  4(8 in²) +4(24 in²) +36 in² = (32 +96 +36) in² = 164 in²

__

Alternatively, you can draw a 14-inch square around the whole figure, then subtract the areas of the four corner triangles that are not part of the octagon. The area computed that way would be ...

  (14 in)² - 4((1/2)(4 in)(4 in)) = 196 in² -32 in² = 164 in²

A regression equation that predicts the price of homes in thousands of dollars is t = 24.6 + 0.055x1 - 3.6x2, where x2 is a dumm
AveGali [126]

Answer:

a) On average, homes that are on busy streets are worth $3600 less than homes that are not on busy streets.

Step-by-step explanation:

For the same home (x1 is the same), x2 = 1 if it is on a busy street and x2 = 0 if it is not on a busy street. If x2 = 1, the value of 't' decreases by 3.6 when compared to the value of 't' for x2=0. Since 't' is given in thousands of dollars, when a home is on a busy street, its value decreases by 3.6 thousand dollars.

t(x1, 0)= 24.6 + 0.055x1\\t(x1, 1) = 24.6 + 0.055x1 - 3.6\\t(x1, 1) = t(x1, 0) - 3.6

Therefore, the answer is a) On average, homes that are on busy streets are worth $3600 less than homes that are not on busy streets.

<em>Independent variables are variables of a quantity that are not affected by any conditions. </em>

<em>Dependent variables are variables  of a quantity that change if conditions relative to that variable changes.</em>

For example, we generally we take x as independent variable by x variable and dependent variable by y variable.

To find the rate of change we get two values of independent variable (x's) and two values of dependent variables (y's) to get two coordinates in form of

(x,1,y1) and (x2,y2).

<h3>And we can find the rate of change by applying slope formula</h3>

m= \frac{y_2-y_1}{x_2-x_1}.

The cost of a banquet can be calculated using the function
kotykmax [81]

Answer:

3 people attended the banquet

Step-by-step explanation:

The function is given as:

b = 75 + 15n where

b represents the total = 122

n represents the number of people attending = ??

If the total cost of the banquet is 122, how many people attended the banquet?

Hence,

122 = 75 + 15n

122 - 75 = 15n

47 = 15n

Divide both sides by 15

n = 47/15

n = 3.1333333333

Approximately to the nearest whole number = 3

Therefore, 3 people attended the banquet.
