Select all of the following equation(s) that are quadratic in form. x4 – 6x2 – 27 = 0 3x4 = 2x 2(x + 5)4 + 2x2 + 5 = 0 6(2x + 4)2 = (2x + 4) + 2 6x4 = -x2 + 5 8x4 + 2x2 – 4x = 0

um consider it serious or don't :)​

The quadratic equations, or the equations that are quadratic in form, for this problem is given as follows:

The degree of a function is given by the highest exponent that appears in the definition of the function.

A quadratic function is a function that has a degree of 2.

The standard format of a quadratic function is given as follows:

y = ax² + bx + c.

(in which the coefficient a must assume a value different of zero).

The quadratic function in this problem is given as follows:

6(2x + 4)² = 2x + 4 + 2.

As (2x + 4)² = 4x² + 16x + 16, meaning that the highest exponent would be of 2.

However, equations of the fourth degree can also be quadratic in form, as long as the exponents go as follows: 4, 2 and 0.

Hence these following equations are also quadratic in form:

They are classified as quadratic in form because a transformation such as y = x² can make them quadratic.

Using traditional methods it takes 101 hours to receive an advanced driving license. A new training technique using Computer Aided Instruction (CAI) has been proposed. A researcher believes the new technique may reduce training time and decides to perform a hypothesis test. After performing the test on 280 students, the researcher decides to reject the null hypothesis at a 0.05 level of significance.

What is the conclusion?
a. There is sufficient evidence at the 0.02level of significance that the new technique reduces training time.
b. There is not sufficient evidence at the 0.02 level of significance that the new technique reduces training time.
