Question

the pie chart shows the information about the favourite ice cream flavour of each student in a school there are 720 students in a school complete the table​

Answer 1

last 2 figures are 240 and 240

Explanation:

given the pie chart

the sum of the angles in the chart is 360°

chocolate has 90° , that is

`(90)/(360)` =
`(1)/(4)` , then

`(1)/(4)` × 720 = 720 ÷ 4 = 180

------------------------------------

vanilla has 30° , that is

`(30)/(360)` =
`(1)/(12)` , then

`(1)/(12)` × 720 = 720 ÷ 12 = 60

--------------------------------------

strawberry and mango have the same number of students

the value of x° is

x = 360° - (90 + 30)° ÷ 2 = 360° - 120° ÷ 2 = 240° ÷ 2 = 120°

strawberry has 120° , that is

`(120)/(360)` =
`(1)/(3)` , then

`(1)/(3)` × 720 = 720 ÷ 3 = 240

mango is the same as strawberry , that is 240 students

--------------------------------------------

Entries in table should be

chocolate → 180

vanilla → 60

strawberry → 240

mango → 240
