Answer:
Mean =sum of fx ÷ sum of f
meaning that frequency multiplied by number of visits all added together divided by the sum of the frequency will give you the mean
Y = -3x-3 has one real solution.
Y= x^2 -3x + 5 has no real solutions because b^2 - 4ac, the discriminant, is less than zero.
I think its 7 not 100% good luck tho
- two consecutive integers
<u>-4 and -3</u>
