Answer:
B. f(x) = 7000x + 4000
Step-by-step explanation:
To find the best function for this situation, we need to list down all the things that we know first.
We currently have:
35000 total seats
4000 fans
11000 fans after an hour
So that means that after an hour, we had:
11000 fans - 4000 fans = 7000 fans
At one o'clock we had 7000 more fans arrive.
So we can assume that:
x = number of hours
f(x) = 7000x + 4000 will be the best function to use to find out if there that 90% of the stadium will be filled by game time.
To test this function let's use it:
f(1) = 7000(1) + 4000
f(1) = 11000
This is after hour 1.
Now let's see after hour 4 since the game starts at 4.
f(4) = 7000(4) + 4000
f(4) = 28000 + 4000
f(4) = 32000
So 90% of 35000 is:
35000 x 0.90 = 31500
By game time we have 32000 fans which is above 90% of the total number of seats.
So the stadium owners estimate is correct.
Answer:
x=1
Step-by-step explanation:
8+2x-7x=5(x-3)-2(6x-8)
8+2x+7x=5x-15-12x+16
8+15-16=5x-12x-3x-7x
23-16=-7x-3x-7x
17=-17x
x=1
Answer:
6.3
Step-by-step explanation:
The 1st number is odd, less than 5, so it might be 1 or 3, the probability is 2/10
But if the sum has to less than 5, than *when 1st number is 1, the second number can only be 1.2.3
and *when 1st number is 3, 2nd can only be 1
*1: 3/100
*2: 1/100
3/100+1/100=4/100
so the answer should be (4/100)/(2/10)=2/10=1/5
