Answer:

Step-by-step explanation:

probabilty distribution= interval of x/total area of the distribution

OR P(x)= frequency of x/total frequency(N)*the interval of x(w)

x f probabilty f/N*w

16 10 0.2

17 16 0.32

18 20 0.4

19 4 0.08

w is the width of the bar( interval) 17-16=1

N=10+16+20+4=50

( only need to draw histogram)

Answer:

x = 1 or x = -4 or x = -6 thus d: is your answer

Step-by-step explanation:

Solve for x over the real numbers:

x^3 + 9 x^2 + 14 x - 24 = 0

The left hand side factors into a product with three terms:

(x - 1) (x + 4) (x + 6) = 0

Split into three equations:

x - 1 = 0 or x + 4 = 0 or x + 6 = 0

Add 1 to both sides:

x = 1 or x + 4 = 0 or x + 6 = 0

Subtract 4 from both sides:

x = 1 or x = -4 or x + 6 = 0

Subtract 6 from both sides:

Answer: x = 1 or x = -4 or x = -6
