Solve the system of equations
using Cramer’s Rule.
1. Find the determinants:
2. Now find unknown variables:
Answer: the minimum number of determinants that are needed to solve for all unknowns in the system of linear equations is 3.
Answer:
89.44%.
Step-by-step explanation:
Let's work out the probability he misses both throws:
Prob( he misses both throws) = (1-0.78) * ( 1 - 0.52)
= 0.22*0.48
= 0.1056.
So the probability he makes at least one free throw = 1 - 0.1056
= 0.8944.
(It is 1 - 0.1056 because the default of missing both throws is either making one throw on first or second attempt, or making both throws).
The answer is going to be 9,420,000
Answer:
i think 1,000,000,000
Step-by-step explanation:
Answer: C. (-7x+9)(x-2)
Step-by-step explanation:
1. Factor out the negative sign.
−(7x^2+5x−18)
2. Split the second term in 7x2+5x−18 into two terms.
−(7x^2+14x−9x−18)
3, Factor out common terms in the first two terms, then in the last two terms.
−(7x(x+2)−9(x+2))
4. Factor out the common term x+2x+2x+2.
−(x+2)(7x−9) or (-7x+9)(x-2)
