0.75 degrees Celsius

Step-by-step explanation:

The first step is to add all the numbers:

-3 + (-1) + 0 + 2 + 4 + (-4) + 2 (-3) + 8 + (-2) + 5 + 1 = ?

Simplify:

-3 - 1 + 0 + 2 + 4 - 4 + 2 - 3 + 8 - 2 + 5 + 1

= -4 + 2 + 2 + 5 - 2 + 6

= -2 + 2 + 3 + 6

= 3 + 6

= 9

Then divide by the number of numbers you added. Since there are 12 numbers, you divide by 12:

9/12 = 0.75

Therefore, the answer is 0.75.

I hope I helped and have a great day! ^-^

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

the answer will be b x² +x-1
