Answer:
(x²+x-12)(x²-5x-6)= x².x²+ x².(-5x)+x²(-6)+ x.x²+x.(-5x)+x.(-6)
(-12).x²+(-12)(-5x)+(-12)(-6)
= x⁴-5x³-6x²+x³-5x²-6x-12x²+60x+72
=x⁴-4x³-23x²+54x+72
Answer:
H0: μ ≤ 68,800
H1: μ > 68,800
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (H1) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
For the case above;
The Null hypothesis is that the average attendance at games is less than or equal to 68,800.
H0: μ ≤ 68,800
The alternative hypothesis is that the average attendance at games is over 68,800.
H1: μ > 68,800
Answer:
10:6, 15:9, 20:12
Step-by-step explanation:
just add 10:3 to the number
-1/3
-2/2
-2/3
I think is this correct guess
