SAT math scores follow a normal distribution with a mean of 511 and a standard deviation of 110. Suppose we choose a student at random. For each question, sketch the normal curve, shade the appropriate area, calculate a z. score and then answer the question.

1. What is the probability that the student scores less than 450?
2. What is the probability that the student scores greater than 600?
3. What is the probability that the student scores between 450 and 600?
4. Doc scored a 692. What is P(x > 692)?

hi how are you doing today, if you need just ask me.

step-by-step explanation:

1/6

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
