Apoll showed that 48 out of 120 randomly chosen graduates of california medical schools last year intended to specialize in family practice. what is the margin of error for a 90 percent confidence interval for the proportion that plan to specialize in family practice?

+-4.8

Step-by-step explanation:

4.8 is 10% of 48, so it can up or down by that much.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

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
