d) in grade 8, 10 students liked sandwiches.

C) In Grade 8, 40% of students liked noodles.

Step-by-step explanation:

Given is the table as follows

Grade            Burger    Sandwich        NOodles   Total

8                      0.50        0.10                       0.40     1.00

9                      0.53         0.20                     0.27     1.00

The entries are showing the relative frequencies of gradewise favourite food

We have to check which one is right from the given 4 statements

A)  In Grade 9, 53 students liked burgers.

This is incorrect because 0.53 means 53% and need not equal to 53 students always.

B) In Grade 9, 73% of students liked noodles.

This is incorrect as from table we find that 27% of grade 9 liked noodles

C) In Grade 8, 40% of students liked noodles.

This is correct from the given table.

D)  In Grade 8, 10 students liked sandwiches

This is incorrect since number of students cannot be calculated from the relative frequency unless total students are given.

C) In Grade 8, 40% of students liked noodles.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
