Answer:
a) The modal average is 3 bedrooms
b) The mean number of bedrooms is 2.825, or 3 rounded.
Step-by-step explanation:
If you lay out all the numbers from lowest to highest, and find the one in the middle, it is 3 bedrooms.
For the mean, if you add up all the number of bedrooms then divide by the total frequency, you get 2.825. This would be 113 ÷ 40.
The expression is an illustration of mathematical statements.
The equation that represents the statement is: 60 = 5 + b
The statement is given as:
<em>60 is 5 more than b.</em>
In equations, "is" represents equals to (=)
So, we have:
60 = 5 more than b.
In equations, "more than" represents addition (+)
So, we have:
60 = 5 + b
Hence, the equation that represents the statement is:
60 = 5 + b

Perimeter of triangle = 3×side
Perimeter of square = 4× side
Side of triangle = 5cm
Perimeter of triangle = 3×5
=15 cm
Perimeter of triangle =Perimeter of square
15cm = 4× side of square
Side of square = 15÷4
=3.75 cm
Therefore ,Side of square is 3.75 cm .
