By using the summation notation we can write the above statement is Σx²
Subtract 2 point from each score and then add the resulting values.
By using the summation notation we can write the above statement is Σ(x-2)
Subtract 1 point from each score and square the resulting values. Then add the squared values.
By using the summation notation we can write the above statement is Σ(x-1)²
Hello there,
Lucy watched more TV on Tuesday.
This is because 1 hour = 60 minutes.
so, 25% of 60 min = 15 min on Monday
and, 79% of 60 min = 47.7 min rounded gives 48 minutes on Tuesday...
Hope this answer helps. Good luck.
