The regression equation for predicting the number of speeding tickets (y) from information about a driver's age (x) is y = -0.065(x) + 5.57. how many tickets would you predict for a twenty-year-old?

Put 20 in the equation where x is, then do the arithmetic.

... y = -0.065·20 +5.57 = 4.27

The equation predicts 4.27 tickets for a 20-year-old.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
