Please help, i cant seem to get this right!!

7ft

Step-by-step explanation:

The shape is a trapezium

Area of Trapezium= (1/2)(a+b)(h)

Area of Trapezium= 40sqft

a= x

b= 9ft

h= 5ft

40= (1/2)(x+9)(5)

40= (5(x+9)/2)

Cross multiply

80= 5(x+9)

80= 5x + 45

5x= 80-45

5x= 35

Divide both sides by 5

x= 7

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
