y<span> = 12x+76 is the answer to your question i know it was a little late but at least other people who would like to know can see it.</span>
Answer:
About 30%
Step-by-step explanation:
1) figure out how many people didn't respond: 1334-931=403
2) divide small number by big number(nearest tenth): 403/1334=.30
3) move decimal to the right two times: 20%
Hi there! With equations like this we want to get our variable on one side and and our constant on the other.
So with 2x + 3 = -7 you'd subtract the constant 3 from both sides of the equal sign to get 2x = -10, then you'd divide both sides by 2 to get x = -5. If you double check your work by replacing x in the original equation with our answer we'd find that 2(-5) + 3 = -7 is correct.
Hope you find this helpful :)

Z-scores are expressed in terms of standard deviations from their means. <span>The standard score is simply the score, minus the mean score, divided by the standard deviation. It is calculated as follows:
z = X- mean / standard deviation
z = 2.7 - 2.4 / 1.5
z = 0.2</span>
