We calculate for the dimensions (the length of the sides) of both the poster and the cube. If the length of the side of the poster is shorter compared to that of the box then, the poster will lie flat in the cube. However, if the poster has a length that is longer than that of the cube then, it will not lie flat in the cube.
length of the poster = sqrt (9 ft^2) = 3 ft
length of the cube = cbrt (30 ft^3) = 3.11 ft
Since, the length of the cube is longer compared to the length of the poster then, the poster will lie flat on the cube.
Answer:
<h2>Biased.</h2>
Step-by-step explanation:
The research is aimed to find if students would choose engineering as their profession.
So, according to the problem, the researcher chose the same number of male students and female students. In that case, the research would be biased. If the researcher chooses the same number of boys and girls, one group will be overrepresented, because in a school, there aren't the same number of male students and females students, that would be a perfect case which doesn't happen in real life.
So, the equivalence of the sample will bias the study, because it would misrepresented the real situation.
Therefore, the sample is biased.

Answer:
• discriminant: 73
• # of real solutions: 2
Step-by-step explanation:
Comparing the equation ...
2x^2 -9x +1 = 0
to the generic form ...
ax^2 +bx +c = 0
we find the coefficient values to be ...
a = 2; b = -9; c = 1
That makes the value of the discriminant, (b^2 -4ac), be ...
(-9)^2 -4(2)(1) = 81 -8 = 73
Since the discriminant is positive, the number of real solutions is 2.
