The diameter of the circle is 8 cm, as
shown. the sum of the top two shaded
areas is the area of half the circle minus
the area of the triangle. the shaded
area below is a 60° sector of the circle.
find the sum of the three shaded areas.

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
