This too pls pls pls

0.333n + 28 ; 33.3 ; $41.653

Step-by-step explanation:

For the best fit line :

The slope of the graph :

Drawing a right angled triangle at any point on the best fit line :

Gradient = (y2 - y1) / (x2 - x1)

Gradient = (45 - 30) / (50 - 5)

Gradient = 15 / 45

Gradient = 0.333

Intercept :

Where best fit line crosses the y - axis = 28

b = 0.333n + 28

The extra cost of each extra call made made is the slope of the graph :

$0.333 = 33.3 cents

Estimated cost of 41 calls

b = 0.333(41) + 28

b = $41.653

Kindly note that, the values used were obtained from a graph which isn't lined, therefore values taken may not be very accurate.

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
