Answer:
in -5y+8x=-18 and 5y+2x=58
x = 4
in -5y+8x=-18 and 5y+2x=58
y = 10
f(x) = x³ - 2x² - 24x
x³ - 2x² - 24x = 0
x(x² - 2x - 24) = 0
x = 0
x² - 2x - 24 = 0
a = 1, b = -2, c = -24
Delta = (-2)² - 4 * 1 * (-24) = 4 + 96 = 100
x = (-(-2) - 10)/(2 * 1) = -8/2 = -4
x = (-(-2) + 10)/(2 * 1) = 12/2 = 6
Answer: 2)
Probability that the questions are answered corectly1/4 = 0.25
probability that they are answered wrong 3/4 = 0.75
probability that 4 out of 7 are corect 7C4(0.25)4(0.75)3 which equals 0.0577
