According to a survey, 2929% of residents of a country 25 years old or older had earned at least a bachelor's degree. you are performing a study and would like at least 1010 people in the study to have earned at least a bachelor's degree. (a) how many residents of the country 25 years old or older do you expect to randomly select? (b) how many residents of the country 25 years old or older do you have to randomly select to have a probability 0.9930.993 that the sample contains at least 1010 who have earned at least a bachelor's degree?

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
