Answer:
The discriminant of the quadratic equation is 0
Step-by-step explanation:
Here, we want to calculate the discriminant of the given quadratic equation
Mathematically, we have the discriminant calculated by the following formula;
D = b^2 - 4ac
where;
b represents the coefficient of x which is -2
a is the coefficient of x^2 which is 1/7
c is the last number which is 7
Substituting these values;
D = (-2)^2 -4(1/7)(7)
D = 4 - 4
D = 0
64% possible that the two chips are the same colour
The volume of the square pyramid is 6 x 6 x 9/3 = 108 cubic cm.
Volume of the cube = 4 x 4 x 4 = 64 cubic cm
Number of cubes needed: 108/64 = 1 11/16 cubes (1.6875)
