1. The sample life insurance premium table illustrates the monthly premium for every $25,000 of coverage.

Vlad1618 [11]

Answer:

A. $23
B. 0.997359

Step-by-step explanation:

1. The policy rates in the table are for $25000 of insurance. Lydia wants $100,000 of insurance, which is 4 times the amount quoted in the table. Hence her premium will be 4 times the quoted premium. Her spot in the table is in the age 24–30 row and the Female Non-Smoker column. Lydia's premium will be 4×$3.50, or $14 per month.

She wants 2 times the amount quoted in the table ($50,000) of insurance for her spouse, so the premium will be 2 times that quoted in the table. His spot in the table is in the age Under 24 row and the Male Smoker column. The premium for his insurance will be 2×$4.50, or $9 per month.

The total of the two premiums will be $14 = 9 = $23 per month.

2. The probability of living another year is the complement of the probability of dying. For a 35–44 year-old male, the probability of dying is 264.1/100,000, about 2.641×10^-3. The complement of that is ...

1 - 0.002641 = 0.997359

Vertex (0,1) x intercepts is - 1 and 1 what is the equation of the parabola?

MrRa [10]

$\bf y=a(x-{{ h}})^2+{{ k}}\\
x=a(y-{{ k}})^2+{{ h}}\qquad\qquad vertex\ ({{ h}},{{ k}})$

those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below

that means, the squared variable is the "x", thus the form is $\bf y=a(x-{{ h}})^2+{{ k}}$

now, we know the vertex is at 0,1, and two x-intercepts of $\pm 1,0$

thus $\bf y=a(x-{{ h}})^2+{{ k}}\qquad 
\begin{cases}
h=0\\
k=1\\
when
\\
x=\pm 1\\
y=0
\end{cases}
\\\\\\
\textit{so.. hmmm let us use the point ... say hmmm 1,0}
\\\\
y=a(x-{{ h}})^2+{{ k}}\implies 0=a(1-0)^2+1$

solve for "a", to see what that coefficient is, then plug it back in the vertex form equation
