Independent sample design is the one in which samples are selected randomly. It is the observation which is not dependent on any other value. The statistical analysis is based on the assumption that the samples are independent. The study in this scenario is not dependent on any other variable and is based on independent sample design.

Find the polynomial with real coefficients, smallest possible degree, leading coefficient 1, such that 2 and 3+i are zeroes of t

Bezzdna [24]

f(x) = x³ - 8x² + 22x - 20

given x = a, x = b are zeros of a polynomial then

(x - a) and (x - b) are factors and the polynomial is the product of the factors

f(x) = k(x - a)(x - b) → ( k is a multiplier )

note that complex zeros occur in conjugate pairs

3 + 1 is a zero then 3 - i is a zero

zeros are x = 2, x = 3 + i and x = 3 - i, thus

(x - 2 ),(x - (3 + i )) and (x - (3 - i )) are the factors

f(x) = (x - 2)(x - 3 - i )(x - 3 + i)

= (x - 2)(x² - 6x + 10)

= x³ - 8x² + 22x - 20

If (5^2)p = 5^12, what is the value of p?

mr Goodwill [35]

Divide both sides by 5^2 (which is 25). So p = (5^12)/25. I can't be bothered to plug in into a calculator but be my guest.
