Answer:
5320$
Step-by-step explanation:
A = 0 (or) B = 0
Solution:
The zero product principle is most probably used to solve a quadratic equation by factoring the factors.
Let us know the definition of zero product principle.
Zero product principle:
The zero product principle states that if the product of two factors is zero then at least one of the factors must be zero.
This means that if AB = 0, then A = 0 (or) B = 0.
Hence, The zero-product principle states that
if AB = 0, then A = 0 (or) B = 0.
Answer:
$720
Step-by-step explanation:
Given :
Mean, m = 600
Standard deviation, s = 120
Z = (x - m) / s
P(Z > x) = 84%
P(Z > x) = 0.84
Zscore corresponding to P(Z > x) = 0.84 will be -0.994
Hence,
-0.994 = (x - 600) / 120
120 * -0.994 = x - 600
119.28 = x - 600
119.28 + 600 = x
719.28 = x
Hence,
X = $720
