Answer:
A or 2
Step-by-step explanation:
Answer:
k=5
Step-by-step explanation:
0.96-1 = -1/k^2
-1/-0.04 = k^2
25=k^2
k=√25
k=5
The equation that best models this situation would be: y=40+30x
Answer:
A: 171.75
B: 170
Step-by-step explanation:
The mean (or average) can be found by...
- add all the numbers together (we will call this y)
- divide the total sum (or y) by the total amount of numbers used to add
Formula:
(x₁ + x₂ + x₃ + ... + xₙ) ÷ n
For A:
(172 + 130 + 173 + 212) ÷ 4 = 171.75
For B:
(136 + 184 + 168 + 192) ÷ 4 = 170
X+16/x=4. x^2+16-4x=0. x=8+-^17
