Answer:
You would subtract -12 from both sides!
Explanation:
The eqaution will become like this:
- 16x + 12 = 0
Then you would solve it with the <u>Quadratic Equation formula.</u>
43 as you substitute 6 in place of x, and then get 36+6+1=43

Answer:
23 students expected to have scores greater than 60.
Step-by-step explanation:
60 is 2 standard deviations above the mean. This translates into a z-score of +2. According to a table of z-scores, the area under the standard normal curve to the left of z = 2 is 0.9772; that to the right of z = 2 is 1.0000 - 0.9772, or 0.0228. This 0.0228 represents the probability that a given score is greater than 60.
This fraction (0.0228) of 1000 students comes out to 23 (rounded up from 22.75).
