A is describing either a rectangle, rhombus, or square, so that's not it. B is the same, C is also a possible rhombus, and so D is the correct answer as a square.

Answer:

Out of 450 phones 18 of them will have a defect.

Step-by-step explanation:

As we know that out of 75 phones 3 of them will have a defect, this means that we are able to calculate how many defects there will be from 450 phones. You can do this by first dividing 450 by 75, this gives you 6. This means that 75 will go into 450 6 times.

From this we are able to work out the number that will have defects. This is because we know that 75 goes into 450 6 times and that for each 75 phones there will be 3 defects. So to work out the number of phones out of 450 that would be defects you would simply multiply 3 by 6, this gives you 18. This shows that out of 450 phones 18 of them will have a defect.

1) Divide 450 by 75.

$450/75=6$
