With rational coefficients (a, b and c), if one zero is rational, that means the discriminant is rational. We can conclude that the other is also rational.
Answer:
We can conclude that this statement is False. Because the Empirical Rule does not apply to data sets with severely asymmetric distributions, since by definition the use of the rule is satisfied just for symmetric distributions like the normal distribution.
And if the distribution is not bell shaped or symmetric then we can't use it.
Step-by-step explanation:
Previous concepts
The empirical rule, also referred to as the three-sigma rule or 68-95-99.7 rule, is a statistical rule which states that for a normal distribution, almost all data falls within three standard deviations (denoted by σ) of the mean (denoted by µ). "Broken down, the empirical rule shows that 68% falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ)".

Answer:
$500=$4c × $3p
because $4 each is 4 times c. and the same for the popcorn
p(x) = 2x2 – 4x and q(x) = x – 3, what is (p•q)(x)
Solution:
Here we have to find p(q(x))
q(x) =x -3
we will plug value of q(x) in x of p(x)
p(x) =2x2-4x
p(q(x)) = 2(x-3)2-4(x-3)
= 2(x2-6x+9)-4(x-3)
=2x2-12x+18 -4x+12
=2x2-16x+30
Sorry if I am wrong I really am
