When evaluating a survey. Jody saw that 549% of the respondents think that the minimum age of those awarded a driver's license should be raised, while 469% think it should remain the same. The margin of error was +59%6. Which statement is true?
OA
The population proportion of those who think the driving age should be rased is definitely greater than the proportion who
think it should remain the same.
OB.
The population proportion of those who think the driving age should be raised is definitely less than the proportion who think
it should remain the same.
OC
The population proportion of those who think the driving age should be raised may or may not be greater than the
proportion who think it should remain the same.
OD.
The population proportion of those who think the driving age should be raised is definitely equal to the proportion who think it
should remain the same.

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
