Answer:
The smaller number is 5
Step-by-step explanation:
Let the smaller number be x
the other number is (17 -x) (we know they add up to 17)
2/3 of the bigger number is written as 2/3 (17 - x)
The smaller number is 3 less than that. (so subtract 3 to get x)
x= 2/3 (17 -x) - 3 <-- We have an equation, solve for x
Check 2/3 x 12 - 3 = 8 - 3 = 5
F(x) = x^2 - 3x - 7
f(-3) = (-3)^ 2 - 3(-3) - 7
f(-3) = 9 + 9 - 7
f(-3) = 18 - 7
f(-3) = 11

Answer:

Step-by-step explanation:
We are given the following in the question:
The owner of a football team claims that the average attendance at games is over 63,500.
He wants to justify that the team needs to be moved to a larger stadium outside the city.
If the attendance is larger than 63,500 the team would be moved to a larger stadium and if it is less than or equal to 63,500 that it would not.
Thus, the null and alternate hypothesis will be designed as:

The null hypothesis says that the average attenders is equal to or less than 63,500 and alternate supports the claim that the attenders average is greater than 63,500.
