I dont know all of them bur i think question 6 is choice C
A score of 85 would be 1 standard deviation from the mean, 74. Using the 68-95-99.7 rule, we know that 68% of normally distributed data falls within 1 standard deviation of the mean. This means that 100%-68% = 32% of the data is either higher or lower. 32/2 = 16% of the data will be higher than 1 standard deviation from the mean and 16% of the data will be lower than 1 standard deviation from the mean. This means that 16% of the graduating seniors should have a score above 85%.

Answer:
2+3y=21
x=2y
Step-by-step explanation:
Each two point shot scores 2 points, so xx two point shots would score 2x points. Each three point shot scores 3 points, so y three point shots would score 3y points. Therefore, the total number of points scored 2x+3yy equals 21
Since Easton scored twice as many two point shots as three point shots, he made more two point shots, so if we multiply 2 by the number of three point shots made, we will get the number of two point shots made, meaning x equals 2y
