Answer is C. Mean is the mid-point value and one standard deviation on either side. (100-85=15 and 115-100=15)
Question 1:
Let X be the number of miles you can drive.
you need to multiply the price per mile by the number of miles and add that to the rental fee.
The total cost has to be less than or equal to the total amount of money you can spend.
The equation is : 0.35X + 26.20 ≤ 200
Question 2:
The cost of the six drinks and the cost of X hot dogs need to be equal to or less than the 18 dollars they gave you.
The cost for the 6 drinks can be simplified to be 6.00
The equation would be:
6.00 + 1.75x ≤ 18
This can be simplified by subtracting the cost of the drinks from both sides:
1.75x ≤ 12

Answer:
The Nikes cost $125.
The Adidas cost $100
Step-by-step explanation:
Let :
- a = # of adidas shoes
- n = # of nike shoes
Solve the bottom equation for a:
Now substitute this for a in the top equation:
- 3a + 4n = 800
- 3(350 - 2n) + 4n = 800
- 1050 - 6n + 4n = 800
- 1050 - 2n = 800
- -2n = -250
- n = 125
The Nikes costs $125.
We can also solve for the Adidas:
Use the previous equation we made:
- a = 350 - 2n
- a = 350 - 2(125)
- a = 350 - 250
- a = 100
The Adidas costs $100

Answer:
√20
Step-by-step explanation:
d = √(x₂-x₁)²+(y₂-y₁)²
d = √(1-5)²+(-4+2)²
d = √(-4)²+(-2)²
d = √16+4
d = √20
