Calculate the area of this trapezium

= 72 cm²

Step-by-step explanation:

A = (b + B)×h/2

= (9cm + 15cm)×6cm/2

= 24cm×3cm

= 72 cm²

72 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = h (a + b)

where h is the perpendicular height and a, b the parallel bases

Here h = 6 , a = 15, b = 9 , thus

A = × 6 × (15 + 9) = 3 × 24 = 72 cm²

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

30005

yes ok
