There are 5 squares of dimensions 3 x 3.
5 x (9) = 45 sq. in.

There are 4 right triangles of leg lengths of 6.
4 x (18) = 72 sq. in.

45 + 72 = 117 sq. in.

Solve the following inequality <br> -2x+12&lt;36
Anestetic [448]
Answer: x > -12

-2x + 12 < 36
Subtract 12 from both sides
-2x < 24
Divide both sides by -2
Because you divided by a negative number, flip the sign
x > -12

Check
Choose a value for x
-11 > -12
-2(-11) + 12 < 36
22 + 12
34 < 36; is True

The following table gives projections of the U.S. population from 2000 to 2100.
PSYCHO15rus [73]

The equation of best fit is f(X) = 2.91964X + 265.86364.

f(65) = 455.64024. It means that the population, in millions, after 65 years from 2000 is 455.64024.

The slope of the line is 2.91964 which means population is increasing at the rate of 2.91964 per year.

Sum of X = 550

Sum of Y = 4530.3

Mean X = 50

Mean Y = 411.8455

Sum of squares (SSX) = 11000

Sum of products (SP) = 32116

Regression Equation = y = bX + a

b = \frac{SP}{SSX} = \frac{32116}{11000} = 2.91964

a = MY - bMX = 411.85 - (2.92*50) = 265.86364

y = 2.91964X + 265.86364

f(X) = 2.91964X + 265.86364

f(65) = 2.91964\times 65 + 265.86364

f(65) = 189.7766 + 265.86364

f(65) = 189.7766 + 265.86364

f(65) = 455.64024

It means that the population, in millions, after 65 years from 2000 is 455.64024.

From the equation, f(X) = 2.91964X + 265.86364

the slope of the line is 2.91964 which means population is increasing at the rate of 2.91964 per year.
