500 because in a normal distribution 50% of the total falls below the mean
Answer:the answer is 9.3
Step-by-step explanation:
Answer:
First choice
-∞ < y< ∞
Step-by-step explanation:
In this function,we need to use graph in order to find out the range.
Graph is attached.
Consider the example
(3x+5) - (x-10)
When we subtract off the (x-10), we are basically subtracting off x and also subtracting off -10. This is the same as adding on 10 because -(-10) = 10
So we would have these steps
(3x+5)-(x-10)
3x+5-x+10
2x+15
Often students forget to distribute the negative all the way through and would have 3x+5-x-10 as an incorrect step. You need to multiply that -1 through to each term, so that's why the distributive property is used.
