PLLLLZZSSZ HELPPP i really need to finish
Andrews [41]

Answer:

Step-by-step explanation:

Equation of the function is,

f(x) = 2x² + 20x + 54

To convert the function in the form of f(x) = a(x - h)² + k

f(x) = 2(x² + 10x) + 54

     = 2[x² + 2(5x) + 25 - 25] + 54

     = 2[x² + 2(5x) + 5²] + 54 - 50

     = 2(x + 5)² + 4

     = 2[(x - (-5)]² + 4

Vertex of the quadratic equation (parabola) will be (-5, 4)

Therefore, f(x) has a minimum value at x = -5,

f(-5) = 4

"The function f(x) has a minimum value of 4, which occurs when x = 5"

According to a recent​ study, 1 in every 10 women has been a victim of domestic abuse at some point in her life. Suppose we have
Schach [20]

According to the given, 1 in every 10 women has been a victim, therefore the probability of a  victim of domestic abuse at some pint is

p=\frac{1}{10} = 0.10

We need to use Binomial distribution to take a randomly sampled of 25 women and asked each whether she has been a victim.

f(x)= ^nC_x (p)^x (1-p)^{n-x}

Where x is the event that shows a victim of domestic abuse at some point.

We need to find the probability of these victim at least 2 has been victim of abuse, so

P(x>=2) = 1- [P(x=0)+P(x=1)]

P(x>=2) = 1 - [^{25}C_0(0.10)^0(1-0.10)^{25-0}+^{25}C_1(0.10)^1(1-0.10)^{25-1}]

P(x>=2) = 1 - [0.07198+0.199]

P(x>=2) = 0.72902

So the probability is 0.729
