Idk what deviation set is but im guessing B because each term went up by 1
28,000 x 25% = 7,000
28,000 + 7,000 = 35,000
The answer is probably 590,000 because isn't it subtraction
Answer:
142
Step-by-step explanation:
Answer:
84
Step-by-step explanation:
Given a quadratic equation in standard form, ax² + bx + c = 0 : a ≠ 0
Then the discriminant is Δ = b² - 4ac
2k² = 10k - 2 ( subtract 10k - 2 from both sides )
2k² - 10k + 2 = 0 ← in standard form
with a = 2, b = - 10 and c = 2, thus
b² - 4ac = (- 10)² - (4 × 2 × 2) = 100 - 16 = 84
