SAT verbal scores are normally distributed with a mean of 450 and a standard deviation of 120. Determine what percent of the scores lie between 450 and 570.

34.13%

Step-by-step explanation:

Given the mean score is 450 and the standard deviation is 120.

-The probability of scoring between 450 and 570 can be calculated as below:

Hence, 34.13% of the scores lies between 450 and 570

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
