Answer: C) y ≥ 3x - 2; ![y\leq \dfrac{1}{2}x+3](https://tex.z-dn.net/?f=y%5Cleq%20%5Cdfrac%7B1%7D%7B2%7Dx%2B3)
<u>Step-by-step explanation:</u>
Blue line:
y-intercept (b) = -2
slope (m) is 3 up, 1 right = 3
shading is above
⇒ y ≥ 3x - 2
Yellow line:
y-intercept (b) = 3
slope (m) is 1 up, 2 right = ![\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D)
shading is below
![\implies \bold{y\leq \dfrac{1}{2}x+3}](https://tex.z-dn.net/?f=%5Cimplies%20%5Cbold%7By%5Cleq%20%5Cdfrac%7B1%7D%7B2%7Dx%2B3%7D)
Answer:
its b
Step-by-step explanation:
You can simplify that answer. So, 24 and 30 are both multiples of 6 so divide them by six and you have your first ratio. 4/5. You can also multiply both sides by the same number and it'll still be equivalent. So, let's say you multiplied it by two, your next ratio would be 48/60 and it would be equivalent. Did this help?

Answer:
64.6
Step-by-step explanation:
One standard deviation is 4.3. Then +2 standard deviations is ...
(+2)(4.3) = +8.6
This amount added to the mean gives ...
56 +8.6 = 64.6 . . . . +2σ from the mean
