1. Draw the points in the coordinate axes, as in the attached picture.

2. AB and CD are parallel, (both are parallel to the x-axis)

3. A is closer to the y axis than D and C is closer to the C closer than B

4. So combining 2 and 3, we conclude that ABCD is a trapezoid.

5. The remaining thing to check is whether the trapezoid is isosceles or not. For this we drop the heights to AB from points C and D,

and see that the distances from the feets of these heights to the points A and B are not equal.

Answer: Trapezoid

ABCD is a trapezium. Since line AB and CD do not vary in y, they are parallel. Lines AD and BC are not parallel, as AD increases in x, and BC decreases in x. A quadrilateral with only one set of parallel lines is a trapezium.

Answer:

P=0.3726 or 37.26%

Step-by-step explanation:

The success, with 41% of probability of occurring, is that the employee believes the company's president possesses low ethical standards. For more than 8 and less than 12 successes, it means the probability of having 9, 10 or 11 successes (all these summed).

The formula is:

$b(x;n,p)= \ _nC_x*p^x*(1-p)^{n-x}$

Where x is the number of successes,n the number of trials, p the probability of success, $_nC_x$ refers to the combinations that can occur, and it's formula is:
